Roads connect people. Good roads are absolutely vital for a country and a continent’seconomy and welfare. As the world population grows, the world becomes “flat,” andhumanity pushes its frontier into the far corners of the globe, the need for transporting

goods and people faced with new technical challenges such as accommodating heavyvehicles, increased number of load repetitions, use of new materials for increased andimproved pavement life and building through difficult terrain grow significantly. At no time inthe history, the need has ever been so great to build and maintain long lasting and goodperforming pavements. The developing countries of the world have embarked on the task ofbuilding new roads in an unprecedented scale, while developed countries are facing aHerculean task of maintaining and rehabilitating their existing road assets.

At the same time, building, maintaining, and rehabilitation of roads pose a tremendouschallenge to the society – in the form of their adverse impact on our environment. And thisdichotomy – need versus harmful effect – offers a grave challenge. Stated simply, thechallenge is how do we design and construct good pavements so that they perform well,last longer and the construction has a minimum or no impact on our environment?

Before delving into books full of equations and complex theories, we need to take a stepback and ponder on three very basic issues: One—how do we effectively utilize theadvances in modern science and technology in building better and long lasting pavements?Two—how do we properly consider the pavement network as part of our overall builtenvironment in which we live? and three—whose responsibility is it to face the abovechallenge - the government or the private enterprise or the public?

The building of better performing and long lasting pavements is itself a sustainablepractice – it provides a safe and functional mode of transportation to all and helps usprolong the maintenance and rehabilitation cycles and thus helps us reduce the use of newmaterials and energy. Thus, it provides social, economic, and environmental sustainability.Advanced concepts and practices of utilizing materials, mix design, construction techniquesand proper specifications can help us achieve this goal. While Professor Kandhal’scomprehensive article on advances in bituminous road construction provides an overview ofall relevant topics, Sehgal and Abele’s article gives a perfect example of the application ofadvanced concepts in the form of stone mastic asphalt. Since pavements are not isolatedsystems, their construction, maintenance and rehabilitation must be considered in conjunctionwith the other parts of our natural and built environment. Proper layout design, selection oftype of pavement and construction practices can effectively reduce or eliminate the harmfuleffect on our environment, as discussed in an article on sustainable pavements byMr. Mallick and Mr. Veeraragavan.

The answer to the last question lies in the concept of shared responsibility. We, asworld citizens, are all responsible for the construction of an efficient infrastructure that hasminimum impact on our environment. Shared responsibilities, partnership and cooperationbetween private and public organizations, and the availability of properly trained personnelare the key factors to ensure the most efficient construction process that can result in asignificant improvement in the transportation infrastructure – as evident from Mather’s andKumar’s excellent article on the East Link project in Australia.

Industry NewsADB’s AssistanceADB has announced its $7.4 billionassistance to India. Bank’scommunication said that the ADBand the Union Government haveagreed to a new three-yearbusiness plan that will providelending assistance of $7.4 billion to support inclusive andenvironmentally sustainable growthin the country. A major thrust ofADB’s India Country OperationsBusiness Plan (COBP) for 2011-13,the communication said will be tosupport infrastructure development,particularly through PPPprogrammes. The Bank has notedthat supporting the government‘sefforts to redress inter-statedevelopment and economicdisparities is also the keycornerstone of the COBP which isaligned to the country’s XI Plan(2007-12). Continued assistance fordevelopment of the vital energysector by means of programmesinvolving clean and renewableenergy is another key focus area.The assistance is aimed at initiatingprojects in different states of energy,urban development. We are lookingforward to work closely with India inimplementing the programmes inCOBP to help promote inclusivegrowth and reduce poverty in thecountry, said ADB Country Director(India) Hun Kim.

Indian Firms Keenon Hajigak MinesLeading private and public sectorfirms including Tata, Essar, Sail,NMDC, and RINL are among the15 Indian companies who haveshown their interest in developingthe Hajigak mines in Afghanistan.These companies may bid for theassets to offer in consortia, or maygo alone in the upcoming auction.Afghanistan has invited EOI’s for

multiple exploration concessionsfalling within the Hajigak mines. TheAfghan government is very excitedwith the participation of Indian firmsin this deal and also expects thatthe Indian companies should setup steel and mines processingplants near Hajigak. The country isreported to be sitting on over $2.5trillion worth of untapped mineraldeposits with huge copper reserves.

Global ProductivityTrendsGlobal economic productivity whichrallied strongly last year due toeconomic recovery, is likely to dropdown in 2011 in advancedeconomies. However, the Indianproductivity is increasing faster thanChina, says a report. ThoughChina’s productivity has driven itsgrowth story, the wheel could soonbe turning. With investment surgingin India, its productivity is set togrow over four percent compared tothree percent of China. An ICRIER study report states that between2004 to 2009, India’s productivityhas grown by 3.9 percent perannum while in China it has beenmuch less. But sustaining thisgrowth for long is not an easy taskunless the manufacturing chips in to overtake productivity trends seenin telecom, which is pushingproductivity graph in India higher. Ifresources become more productive

and unorganized manufacturinggets organized, productivity in theentire manufacturing could go up.At present, manufacturing lags dueto high share of unorganized sector.This holds good for other sectorswith mushroom growth ofunorganized players in every sectorsfrom textiles to transport and relatedactivities.

DDA Urges to Ropein Private BuildersThe new minister of UD, Mr. KamalNath in a review meeting on theworking of DDA said that DDAshould go in for public partnershipmodel and shift its focus from beingland-owning agency. Though theproposed model for DDA is yet tobe firmed up, various options areunder consideration. In case of LIGprojects, private sector could beroped in to develop malls, hospitalsand schools along with theapartments. Another option is torope in the private sector to buildon DDA's land bank. PPP modelhas been tried in the case of theCWG Village where Emaar MGFbuilt the complex on the banks ofYamuna, where DDA incurredlosses in the transaction. The newminister is also reviewing theschemes under JNNURM andcalled for required reforms inmunicipal bodies.

NHBFhas asked the Finance Minister toallow usage of duty-free importedcapital goods for road constructionbusiness rather road projects. It hasalso asked the term for tax holidayto be defined with greater clarity. A10-year tax holiday is available toenterprises developing newinfrastructure facility, but the term isnot well defined, said the Federationin its Budget memorandum.

Realtors on the other hand,want tax holiday to stay and sosops for buyers in the housingmarket. The Confederation of Real

Estate Developers Association ofIndia (Credai) has sought extentionof tax holiday to industry parks upto March 2015, and amendmentsto help townships of 10 acres andabove to qualify for tax deductionunder infrastructure facility. This isin addition to tax sops for the firsttime home-buyers from 2011,besides enhanced income taxdeduction limits. It has askedservice tax abatement to beincreased from 75% to 90%.

The construction equipmentsector too wants rationalization intax regime, excise duty cut,clarifications on multi-tax regimeand uniformity in state taxes andlevies.

Targeting a double digit growth forthe 2011-12 fiscal the governmentin its Budget proposals has injectedthe biggest ever hike in infraspending by 23 per cent to`2,14,000 crore and ensuring freeflow of funds to achieve the growthtarget. It has also pushed the limitfor FIIs investors in five yearstradable infra bonds from the current$5 billion to 25 billion per annum.Alongside the domestic investorshave also been allowed to invest`30,000 crore in tax free bondsensuring sufficient funds for keyinfrastructure segments includingrailways, ports, highways andhousing sector. In addition, thegovernment in its Budget proposalshas allowed National HighwayAuthority of India (NHAI) to increaseits fund raising limit from the current`4,000 crore to `10,000 crore perannum by way of selling tax freebonds. Ensuring sufficient funds forthe infra spending, the governmentapart from allowing the purchase oftax free bonds and extendingincome tax exemption on tax savingin infrastructure bonds up to `20,000for one year, it is also setting up aninfra debt fund to promote foreigninvestment in the infrastructure

sector.Pushing affordable housing

sector to new high, the governmenthas increased the interest subsidyon a home loan up to `15 lakh fromthe current `10,000 to `15,000 perannum, which will in turn boost lowcost housing across the country.Similarly, the government in itsBudgetary proposals has also

extended the tax holiday by a yeartill 2011-12 in the form of exciseexemption on domestic powerequipment and reduction inwithholding tax and the initiative isall set to boost to the power sector.Extending an open invitation toforeign companies engaged in portand logistics business, thegovernment in its Budget proposalshas allowed them to invest ` 5,000crore in tax free bonds. It has alsoprovided full exemption from importduty on spares and capital goodsrequired for ship repairing units.However, steel and cement pricesmay go northward as the Budgetproposed a 2 per cent increase inexcise duties on steel products andin regard to cement it is proposingto replace the existing dual exciserates on cement, based on sellingprice with a single rate, which willresult in pushing the retail price ofthe product. So far so good, theBudget gives a well deserved leg-up to infrastructure and housingsector. How these proposalsimplemented in a timely manner toboost infrastructure development arethe concern, hope and expectationacross the board.

We Need PavementsThe need for safe, durable andsmooth riding pavements onhighways and in airports cannot becontended. Construction andmaintenance of pavements costmoney – which is mostly providedthrough taxes that are collected fromthe citizens. The money is spent onemploying workers, quarrying andmanufacturing usable products,transporting them, and laying downand compacting the materials. Inthis whole process, which getsrepeated to different extents duringthe maintenance and rehabilitationcycles, man-made material is laiddown to cover virgin (most likelyarable) ground (making it un-arablefrom that point onwards), asignificant amount of naturalresources is uti l ized, (nonrenewable) energy is consumed,landfills are created, and differenttypes of chemicals (in the form ofgases) are emitted to theenvironment (all of these processes

are irreversible). Thus, pavementengineering is a destructive andhigh impact activity. But rememberthe first sentence of this paragraph– and herein lies the dichotomy ofmodern civilization – you buildsomething that you need but in theprocess you affect the earth in anirreversible harmful way. So what isthe solution?

There is most likely not “a”solution, but multiple ones. In fact,they are more like “tools” that existin the pavement engineer’s toolbox,which could be used, as the needarises. It is the intent of this articleto describe a few of such importanttools and their impacts.

First ConsiderationFirst and foremost, the pavementinfrastructure should be viewed aspart of a larger “system,” and notviewed alone. Buildings, pavementsand natural ground/water bodies(nature) form the built environmentin which we live and breathe.Hence, pavements need to be

compatible and if possible,complementary to the other twocomponents – buildings and nature.This means construction andmaintenance of pavements shouldnot be taxing the natural resources,energy util ization should beminimized, byproducts in the formof emissions should not be harmfulto the environment, and the layoutof the pavement should not besignificantly impacting the naturalenvironment. Broadly speaking, thisincludes layout and type, designand construction of pavement. It isonly through this process we canensure that our future generationswill have no/less problem ofcontinuing the work of building ormaintaining/rehabilitating thepavement infrastructure. And, this isthe very essence of sustainability.True sustainability consists of threeaspects - social, economic andenvironmental sustainability. Thediscussions in the followingparagraphs refer to either one or

more of these three different typesof sustainability.

Design of Layout ofPavementsSome of the more important issueswith the layout/geometric design ofa pavement can be summarized asfollows:1. Protection of forests: forests

provide a home to many speciesof plants and animals and at thesame time serve as a source ofeconomic products such astimber and enjoyment for tourists.Roads should be preferablydesigned away from forests, or ina way that creates minimumimpact on them.

2. Protection of wild l ife:Considerations must be made toprovide features that wouldminimize the effect of roadconstruction on animals andsubsequent vehicle-animalcollisions (such as protectedcross overs).

3. Consideration of uniquegeological conditions, such assteep slopes with vegetation orcaves/landforms should be made.Precaution should be taken toavoid such areas where a slightdisturbance of the landscapewould lead to a significantirreversible disturbance of thelocal environment.

4. Context-sensitive design shouldbe adopted: the layout of the roadshould conform to the values ofthe communities through which itis passing, by making sure that itis integrated with the localcharacter – such as flora andfauna in rural areas.

5. Access to critical areas, such ashospitals and police stationsshould be provided, such that theroad helps the local communitiesand in return the people valuethe road.

6. Consideration of the impact ofdiversion routes on the localenvironment, during the

construction of new pavementshould be made. Properforecasting methods andmitigation procedures should beadopted.

7. Consideration of traffic growthand providing adequate room forfurther growth should be made,such that traffic saturation doesnot lead to a drastic change inthe character of the communityand significant construction activitycould be avoided for a longerperiod of time.

The issues listed above canbe represented in terms ofproblems such as deforestation,noise pollution, crossing of habitatareas, flooding/storm watermanagement, creation of wastage,urban heat island effect, drinkingwater pollution, air pollution, trafficjams, soil erosion, and use ofnatural resources and energy.

The above problems could besolved with the use of one or moreof a variety of methods, whichinclude habitat connection acrossroadways through underpasses oroverpasses, fencing along the roadfor animal protection, amphibianrescue fences, storm water pollutionprevention plan, pedestrian, bicycle,and transit access, noise barriers,buffer zones, or specially plantedslopes/embankments to reducenoise pollution, intersections withinterchanges, use of pervioussurfaces in pavement or shoulders,runoff treatment practices to cleanrunoff water, avoidingsensitive aquifers,making the locations ofservice connectionseasily accessible,providing easy access toemergency services, anddefining animplementation strategyto be followed duringconstruction.

Some of thesedesirable features areshown in Figure 1.

Construction ofPavementsFor construction of asphaltpavements the key factors that needto be considered are using localmaterials (to reduce transportationrelated energy expenses), loweringthe need for new materials,reducing production andconstruction temperature, usingmore environment-friendly products(such as bio-asphalt), andenvironment-friendly layers/mixes(such as those that would allowthe percolation of water into thesoil layers and hence facilitaterecharging of aquifer, and those thathave reduced noise levels), utilizingmixes that would allow recycling orreuse of discarded materials, andlonger lasting pavements, andconducting a proper life cycleanalysis.

The favorable impact of usingsustainable pavements is farreaching. For example, if a recyclingprocedure is used to rehabilitatean existing pavement, then thefollowing benefits can be ensured:1. Less use of new natural

resources such as mineralaggregates

2. Significant reduction intransportation cost of newmaterials

3. Less amount of energy use inobtaining and processing newmaterials (aggregates)

4. Less amount of energy use in

manufacturing new materials(asphalt binder, cement)

5. Less emission and pollution ofthe environment

6. Reduction or avoiding of fillingup precious landfill space

7. Significant reduction in overalltransportation energy, specificallyif an in-place recycling process isutilized.

There is a variety of recyclingtechniques that are available today,each having its applicability underspecific conditions, as shown inTable 1.

A pervious layer in roads wouldallow the percolation of rain waterto the lower layers, and offer thefollowing benefits, that are relatedto both groundwater as well asstorm water/flood control:1. Recharge of ground water, and

hence a reduction in the potentialof lowering of groundwater andthe related problems.

2. Detention of rain water and hencea lowering of the storm watervolume that ends up in roadsewer system;

3. Filtering of storm water that iscontaminated by different methodson the road; studies show that asignificant amount of suspendedsolids, phosphorous, zinc andhydrocarbons are removed.

For asphalt pavements, a typicalpervious pavement is obtained byusing asphalt treated permeablebase over a layer of pervious stonelayer over the subgrade (with filtermaterial) as shown in Figure 2. Forconcrete pervious pavements, there

is the option of using interlocking/segmented concrete pavers. Evenif not used in mainline, storm watertree trenches can allow thedetention of a significant amount ofstorm water for sufficient timebefore releasing it into the sewersystem (Figure 3).

Low energy mixes, particularlywarm mix asphalt are becomingmore common these days, becauseof their inherent advantage of lowerenergy cost and lower emissionpotential. Another key factor inconsidering warm mix asphalt isthe fact that because of lowertemperature, the asphalt binderundergoes less aging, and hencea better pavement mix is obtainedduring construction – whichtranslates to longer life and henceless frequent rehabilitation cycles.There are different types of WMAtechniques available, such aszeolites, wax, emulsion and foam -with newer products and techniques

being developed, and one or moresuitable methods can easily beadopted for regular use by theindustry. The selection of thespecific method should be madeon the basis of the availability ofthe material, expertise andexperience with that specifictechnology.

The use of bindersmanufactured from bio-resources isbeing researched and conducted indifferent parts of the world. Thesebinders are essentially derived frombiomass – agricultural and forestresidue with the help of biochemicalor thermochemical processes. Onesuch example of bio binder whichis fully derived from vegetable isVegecol from COLAS. Such binderscan be utilized for modifying asphalt(< 10% replacement), extendingasphalt binder (>25% replacement)or totally replacing asphalt. Differentgrades of such binders could alsobe used for cleaning roadequipment or partially replacingfluxing agents. The advantages ofusing such binders are significantreduction in pollution – no SOx andmajor reduction in NOx emissions,and manufacturing from 100%renewable agricultural products.Furthermore, the temperature of mixproduction could be reducedsignificantly.

One of the most excitingtechnologies that are beingdeveloped in pavement engineering

is the combined use of the recyclingand warm mix concepts to producegood performing and long lastingpavements. Binder from renewablesource could also be used in thisprocess. Using sophisticatedmaterials and plant/process controltechnology, it is now possible toeffectively recycle close to 100%reclaimed asphalt pavement (RAP)material, at a reduced temperature(for example below 130oC asopposed to 150oC) to meetemission requirements, and stillobtain a pavement which hasexcellent performance under bothhigh and low temperatures, andwhich can be opened to trafficquickly after construction, even at atemperature which is higher thanthat at which conventionalpavements could be opened.Overall, this translates to savingsin money and time, materials andnatural resources and energy, and

significant reduction in emission.Example of such a project (inGermany) is shown in Figure 4.

Recycling of discarded tires inthe form of crumb rubber in asphaltpavement mixes is now an acceptedpractice in many parts of the world.Apart from allowing the user to avoidthe filling up of precious landfillspace with hazardous waste, thisprocess allows the userto:1. Incorporate more

asphalt binder (thickerfilm) in mixes to make,them longer lasting anddurable

2. Use a coarsergradation for specificuses such as drainageof water.

3. Reduce noise levelsfrom pavementssignificantly.

The key to successful use ofrubber modified asphalt binder issuccessful incorporation andretention of the rubber into thebinder/mix. As is the case for manytechnologies, this is heavilydependent on available plant andconstruction equipment. Forexample, appropriate technologymust exist to uniformly blend thecrumb rubber mechanically orchemically with the binder, ensurethat the binder remains in that stateduring transportation, and for properquality control test methods to testand prevent the separation of therubber and the binder prior tolaydown and compaction. In termsof recycling of other materials,artificial aggregates such as blastfurnace slag, generated from steeland iron production could besuccessfully incorporated in pavingmixes.

The production of Portlandcement, the key constituent inconcrete pavements and clinkerrequired for manufacturing ofcement, are a major source of CO2emission in the modern world. Theuse of limestone and supplementalcementitious materials (SCMs, suchas fly ash from thermal powerplants using coal, and rice huskash) provide attractive options ofreducing the use of cement andthereby cutting down its CO2footprint. Blended cement,consisting of Portland cement andSCMs are becoming popular. Formaintenance of concrete

pavements, modern techniquessuch as dowel bar retrofits, crossstitching, partial-depth repairs, jointand crack resealing, slabstabilization, diamond grinding couldbe used to improve the conditionsof concrete roads and at the sametime avoid or reduce the need forenergy intensive major repairs/rehabilitation work.

The concept of perpetualasphalt pavement has been recentlyproposed as a sustainabletechnology. The objective of thistechnique is to provide thick andappropriately constructed (withspecific mixes for different layers)layers such that the crit icalresponses (such as tensile strain)in the pavement are kept very low,and as a result no major structuralfailure could be expected for a longperiod of time. The onlydeterioration that could be expectedwill be in the form of surfacedistresses, which could be relativelyeasily and economically addressedby less involved rehabilitationprocedure, such as in place surfacerecycling. Obviously, thesepavements would cost more thanconventional pavements initially butif constructed properly, they allowthe users and the highwayagencies to enjoy a better qualityand durable pavement withsignificantly reduced cycle ofrehabilitation (the pavements needto be maintained properly), andhence significant reduction inactivities that could negatively impactthe environment.

In terms of longevity, proponentsof the concrete pavement industryargue that the longer life of concretepavements translates to reducedneeds for new natural resources,energy and waste disposal. Anotherimportant factor is that because oflower deflection in concretepavements and hence lower rollingresistance, the mileage isincreased by about 3.85% inconcrete pavements over asphaltpavements (with similar

smoothness) – which translates tolower amount of fuel spent andhence lower amount of greenhousegas emission. Furthermore,because the surface of a concretepavement reflects a higher amountof solar energy than asphaltpavement, concrete pavement helpsin reducing the indirect contributionof pavements towards the urbanheat island effect. And at nighttime,the lighter color of the concretepavement surface helps in asignificant reduction in the amountof energy that is needed forillumination. However, note thatsmoothness has a significantpositive effect on gas mileage,asphalt pavements are in generalsmoother than concrete pavements,and the reflectivity of asphaltpavements can be improved byusing surface gritting or chip sealswith light colored aggregates,colorless synthetic binders andsurface paints, and the surfacetemperature could be reduced withthe help of open graded frictioncourse.

Life cycle analysis (LCA) inpavement engineering is anestablished concept, and is utilizedin many, if not most, high costprojects. However, traditionally, thecost is evaluated in terms ofmaterials/construction/salvage costonly. For sustainable pavementengineering, the environmental andsocial cost must also be evaluated.Furthermore, the cost of extendingthe life of a pavement (and thuslowering the life cycle cost) mustbe evaluated in the context of theamount of natural resources andenergy that are spent on producingthe premium materials that areused to extend its life. The impactof the pavement construction/maintenance and rehabilitationshould be evaluated in terms of allthree components of sustainability– social, economic andenvironmental. Examples of suchframework and components offramework are the Sustainability Life

Cycle Assessment (SLCA), the IRFGreenhouse Gas Calculator, andPaLATE (Pavement Life-cycleAssessment Tool for Environmentaland Economic Effects).

WorkersHundreds of thousands of humanbeings – men, women and in manycases even children work inpavement related projects all overthe world. In many cases, this workgoes on under extreme conditionsof weather, in areas that are remotefrom basic facilities such as schoolor hospitals, and under conditionsof emissions/pollution fromconstruction conditions (smoke/gas/particulate emission). This makesthe entire realm of pavementengineering socially unsustainable.Conditions must be improved suchthat environmental and economicjustice is prevalent among thepavement workers. While there aremany things that need to be done,first and foremost, it is theresponsibil ity of pavementengineers to select materials andmethods such that workingconditions are improved. Forexample, switching to warm mixasphalt instead of hot mix asphaltwill reduce harmful emissionssignificantly (Figure 5). Secondly,engineers and authorities mustenforce strict safety regulations andprovide for the basic necessitiessuch as protective body and eyewears.

Pavement-Building-Nature-SymbiosisAs pointed out earlier, pavementsneed to be considered as part ofthe built environment – going onestep forward, in the future;pavements need to be consideredas part of a symbiotic system thatalso includes buildings and thenature. Imagine a day when we willhave smart pavements, that will beable to self control temperaturesand adapt to changingenvironmental conditions to sustain

loads without deforming or cracking,will be able to harvest heat energyfrom the solar radiation falling onthem, and supply this to buildingsfor various uses, and in return, thebuildings will be keeping thepavements below a crit icaltemperature, thus extending theirlives, and also reducing the amountof heat that is radiated back intothe environment, and henceindirectly reducing the urban heatisland effect. Multidisciplinaryresearch, as indicated in Figure 6,needs to be conducted to makethis vision a reality.

Regulatory Bodiesand Impetus forSustainabilityAdopting sustainable practices canreduce many of the environmentalimpacts of pavement construction.However, both impetus andregulations (“carrots and stick”)need to be in place to acceleratethe adoption of sustainablepractices. Impetus in the form ofprestigious certif ication, firstvoluntary, and then gradually,mandatory, should be introduced.Example of such certification is theUS Green Building Council’sLeadership in Energy andEnvironmental Design (LEED) in the

Figure 5: Range of reduction in emission through the use of Warm Mix Asphalt

United States, which awards silver,gold and platinum certifications forprojects in increasing order ofcontribution towards “improvingperformance across all the metricsthat matter most: energy savings,water efficiency, CO2 emissionsreduction, improved indoorenvironmental quality, andstewardship of resources andsensitivity to their impacts.”Regulatory bodies such as theEnvironmental Protection Agency(EPA) in the US enforce strictemission standards to prevent theemission of harmful gases andparticulates into the atmosphere.

Human FactorPavements are engineeredsystems that need to be planned,designed, constructed,maintained and rehabilitated byknowledgeable and skil ledpeople. However, for achievingsustainable pavementengineering, we need sociallyresponsible engineers, withbroad vision and compassion forhumanity and respect for nature.

Therefore, the preparation forsustainability starts today in ourColleges and Universities withthe students who will be joiningthe profession tomorrow.Professors, administrators andthe tax paying general publicneed to be educated on theimpacts of pavement engineeringand the different ways tominimize such impacts. This canbe achieved by establishingmultidisciplinary centers ofexcellence in sustainablepavement engineering in majorcolleges and Universities inconjunction with the industry andthe government in the differentparts of the country. While

education on existing and newconcepts of sustainability can betransmitted by this method, thecenters should also focus ondeveloping, through research,new sustainable concepts andpractices. And in that research, itis vital that engineers look at thefuture – innovative, sophisticatedmaterials and techniques, aswell as into the past – todetermine what has survived overcenturies without harmfullyaffecting our environment.

This has been a fairly longarticle, and it is time for theauthors (and perhaps the readersas well) to relax and sip a cup oftea– preferably in an Indian claycup– have you ever wonderedwhat a marvel of sustainableengineering the Indian clay cupis? It comes from the earth,serves its purpose in the mostefficient way – even adds flavorto the tea, and then goes backcompletely into the earth, withoutleaving any lasting impact on theenvironment. We, pavementengineers, have a lot to learn fromit!

Advances inBituminousRoad ConstructionIntroductionAn ambitious road construction planis underway in India, which primarilyinvolves bituminous pavements. Atthe present time, Ministry of RoadTransport & Highways (MORTH)Specification for Road and BridgeWorks, 2001 Edition is used forconstruction of all roads includingnational highways. Advances inbituminous constructiontechnologies are made in the worldalmost every year. This paperdescribes such advances in termsof materials, mix design, special

bituminous mixes, and recycling.There is a need to incorporate theseadvances in MORTH specificationswhich are about 10 years old, tokeep abreast of latest technologies.

MaterialsPaving BitumenPrior to July 2006, penetrationgraded road paving bitumen suchas 60/70 was used in India. Thisgrading system was based onempirical penetration test, which isconducted at 25oC. The penetrationtest measures the consistency ofbitumen. Although two 60/70

penetration bitumen samples fromdifferent refineries may have similarconsistency (stiffness) at 25oC, butone may be softer than the otherwhen tested at 60oC, which is closeto the highest pavementtemperature on a hot summer day.Bitumen which is very soft at hightemperature is undesirable becauseit can cause rutting in bituminouspavement under heavy loads.Therefore, the Bureau of IndianStandards (BIS) adopted a viscositygrading system for paving bitumenin July 2006 by issuing standardIS:73:2006. This system is based

on viscosity testing at 60oC.Penetration graded bitumen 60/70was deleted and substituted withviscosity graded VG-30. Similarly,penetration graded bitumen 80/100was deleted and substituted withviscosity graded VG-10.

Although the precedingadvancement has been made, thereis a need to advance further byadopting performance graded (PG)bitumen, especially for nationalhighways. The viscosity gradingsystem gave excellent performanceresults in the US for over 20 years.However, the viscosity gradingsystem, although more rational thanthe penetration grading system,was still based on experience. A50-million dollar, 5-year StrategicHighway Research Program (SHRP)was undertaken from 1987 to 1992to develop a performance basedgrading system for bitumen, whichwas based on engineeringprinciples to address commonasphalt pavement distressproblems. The so-called Superpave(acronym for Superior PerformingPavements) performance gradingsystem includes new bitumen testsand specifications with the followingsalient features:1. Tests and specifications are

intended for bitumen “binders,”which include both modified andunmodified bitumens.

2. The physical propertiesmeasured by Superpave bitumentests are directly related to fieldperformance by engineeringprinciples rather than just theexperience.

3. A long-term bitumen aging test,which simulates aging ofbitumens during 5-10 years inservice, was developed andincluded for the first time.

4. Tests and specifications aredesigned to eliminate or minimizethree specific types of asphaltpavement distresses: rutting,fatigue cracking, and thermalcracking. Rutting typically occursat high temperature, fatiguecracking at intermediate

temperature, and thermal crackingat low temperatures.

5. As shown in Figure 1, the entirerange of pavement temperatureexperienced at the project site isconsidered. New testingequipments were developed/adopted for testing bitumens forthis purpose. A rotationalviscometer is used to measurethe bitumen viscosity at 135oC. Adynamic shear rheometer is usedto measure the viscoelasticproperties of the bitumen at twotemperatures: high temperaturecorresponding to the maximum7-day pavement temperatureduring summer at the project site,and intermediate temperaturecorresponding to the averageannual temperature of thepavement at the project site. Abending beam rheometer and adirect tension tester are used tomeasure the rheologicalproperties of the bitumen at thelowest pavement temperatureduring winter at the project site.

The Superpave performancegrade (PG) bitumen is based onclimate. For example, PG 64-22bitumen is suitable for a projectlocation, where the average 7-daymaximum pavement temperature is

as much as 64oC, and the minimumpavement temperature is –22oC.

The high temperature gradesare PG 52, PG 58, PG 64, PG 70,PG 76, and PG 82. The lowtemperature grades are –4, – 10, -16, -22, -28, -34 and so forth. Bothhigh and low temperature gradesare in increments of 6 Celsiusdegrees.

Example: A project location inRajasthan has a maximum record7-day pavement temperature of70oC in summer and a minimumrecord pavement temperature of –3oC. A PG 70-4 bitumen will bespecified for paving that project.

AggregateMany advances have been made incharacterization of coarseaggregate, fine aggregate andmineral filler used in bituminousconstruction. However, one simpletest for characterizing particle shape& surface texture of fine aggregate(sand) passing 4.75 mm sieve canbe implemented easily in India. Itis desirable to have angular fineaggregate particles in mix so as toresist rutting in bituminouspavements. Whereas angularity ofcoarse aggregate (retained on 4.75mm sieve) can be evaluated by

naked eye, it is not easy to do soin case of fine aggregate particles.The schematic of the testequipment for measuring fineaggregate angularity (FAA) is shownin Figure 2. It can be fabricatedeasily in India. FAA test procedurehas been adopted as standardAASHTO Test 304.

A calibrated cylindrical measureis filled with fine aggregate ofprescribed grading by allowing thesample to flow through a funnelfrom a fixed height into thecylindrical measure. The fineaggregate is struck off at the rim,and its mass is determined byweighing. Uncompacted voidcontent in the fine aggregate iscalculated as the difference betweenthe volume of the cylindricalmeasure and the absolute bulkvolume of the fine aggregatecollected in the measure. Bulkvolume of the fine aggregate iscalculated from its mass and itsbulk dry specific gravity.

This test is based on theconcept that round particles packcloser than angular particles andtherefore produce loweruncompacted void content, that is,lower FAA value. A FAA value of 45or more is desirable to ensure thatthe fine aggregate is angular anddoes not contain any natural sand,which normally has roundedparticles.

Mix DesignMarshall Mix design is currentlyused in India for designingbituminous mixes. In any mixdesign, it is desirable to compactlaboratory specimens to a densitywhich is expected to be achieved inthe bituminous course after 2-3years of densification under traffic.For designing bituminous mixes forheavy traffic, 75 blows each areapplied with a Marshall impacthammer on both sides of thespecimen. This laboratorycompaction level worked well in thepast. However, it was observed inthe US during the 1980s that thefield density of in-servicebituminous pavements wassignificantly higher than thelaboratory design density obtainedwith 75 blows. This was attributedto increased truck tyre pressuresand new tyre designs with stifferside walls. Therefore, 75-blowcompaction level appearedinadequate. Increasing the numberof blows was not desirablebecause it merely causeddegradation (breakage) ofaggregate particles in thespecimen.

During SHRP, a new Superpavemix design method was developedin the US. A Superpave gyratorycompactor (SGC) was developedwhich compacted the laboratory

specimen with gyratory action (seeschematic of SGC in Figure 3)rather than impact compaction asis done with Marshall hammer.Gyratory compaction also simulatesfield compaction with rollers interms of aggregate particleorientation. Depending on the trafficlevel in ESALs (equivalent singleaxle loads) expected on thehighway, desired compaction levelcan be obtained in SGC by varyingthe number of gyrations withoutcausing any significant degradationof aggregate in the mix.

Another advantage of SGC isthat a densification curve (numberof gyrations versus compacteddensity of specimen) is obtainedduring the compaction process. Atleast three different gradations ofthe proposed mix are evaluated inthe Superpave mix design to selectthe gradation which has thestrongest aggregate skeleton.

Special BituminousMixesStone Matrix AsphaltStone matrix asphalt (SMA) wasdeveloped in Germany in the mid1960 and it has been used verysuccessfully by many countriesincluding US as a highly rut-resistant bituminous course, bothfor binder (intermediate) andwearing course for heavy traffic

roads. SMA is tough, stable, rut-resistant mix that relies on stone-on-stone contact to provide strengthand a rich mortar binder to providedurability.

Figure 4 provides a cross-sectional representation of thedifference between SMA and dense-graded conventional bituminous mix.In a conventional dense graded mix,coarse aggregate particles (retainedon 4.75 mm sieve) are separatedby fine aggregate matrix, whichprimarily carries the load. In SMA,coarse aggregate particles havestone-on-stone contact forming astone skeleton which carries theload.

Since SMA mix has relativelyhigher bitumen content, cellulosefiber is added to the mix to minimizedrain down of bitumen in trucksduring transportation of the mix fromplant to project site. Although thecost of SMA is typically about 25-30% higher than the cost of densegraded bituminous mix, it is stilleconomical considering life cyclecosts.

SMA has been widely used inthe US since 1991 for heavy-trafficroads. It must also be used inIndia for heavy corridors especiallywhen overloading is also common.Indian Roads Congress (IRC) hasrecently published a tentativespecification for SMA (IRC:SP:79-

2008), which was drafted by theauthor to facilitate its use in India. Amanual containing detailedguidelines for designing andconstructing SMA mixtures wasdeveloped by the author in the USfor practicing engineers.

Open Graded AsphaltFriction CourseOpen graded asphalt friction course(OGFC) is an open graded hot mixasphalt mixture with interconnectedvoids that provide improved surfacedrainage during rainfall. Therainwater drains vertically throughthe OGFC to an impermeableunderlying bituminous layer andthen laterally to the day lighted(exposed) edge of the OGFConwards to shoulder. In addition tominimizing hydroplaning potentialduring rainfall and providingimproved friction values on wetpavements, the OGFC offers thefollowing advantages compared toother dense graded surfaces: (a)reduced vehicle splash and spraybehind vehicles, (b) reduced tyre-pavement noise, (c) enhancedvisibility of pavement markings, and(d) reduced night time surface glarein wet weather.

Numerous states in the UScurrently using OGFC haveexperienced excellent performancein terms of safety (improved wet

pavement surface friction) anddurability. This has beenaccomplished by one or more ofthe following: use of polymermodified asphalt binders, relativelyhigher bitumen content (by usingcellulose fibers), and/or relativelyopen gradations.

Figure 5 shows an interstatehighway in the US, where OGFCwas used in the lanes on the rightside and dense graded bituminousmix was used in the lanes on theleft side. Note the dramaticdifference: there is no standingwater and absence of splash/sprayon the lanes on the right side duringrain.A manual giving detailed guidelineson design, construction andmaintenance of OGFC wasdeveloped by the author for use bypracticing engineers in the US. Dueto economic considerations, OGFCshould be used in India selectivelyin regions with heavy rainfall andstretches of roads prone toaccidents resulting from skiddingon wet pavement.

Warm Mix AsphaltWarm mix asphalt (WMA) is a fastemerging new technology whichhas a potential of revolutionizingthe production of asphalt mixtures.WMA technology allows the mixing,lay down, and compaction of

asphalt mixes at significantly lowertemperatures compared to hot mixasphalt (HMA). The technology canreduce production temperatures byas much as 30%. Asphalt mixesare generally produced at 150°C orgreater temperatures dependingmainly on the type of binder used.WMA mixes can be produced attemperatures of about 120°C orlower.

The development of WMA wasinitiated in Europe in the late 1990sprimarily in response to the needfor greenhouse gas reduction underthe Kyoto Protocol. WMAtechnologies such as Aspha-min,WAM Foam, and Sasobit weredeveloped during that time. NewWMA technologies such asEvotherm, Rediset WMX, REVIX, LEA(Low Energy Asphalt) and DoubleBarrel Green were later developedwithin the US.

Warm mix asphalt offers thefollowing significant advantages:♦ Energy savings. The most

obvious benefit of WMA is thereduction in fuel consumption.Fuel is used to dry and heat theaggregate. Studies have shownthat lower plant mix temperaturesassociated with WMA can lead toas much as 30 percent reductionin energy consumption.

♦ Decreased emissions. WMAproduces emissions (both visible

and non visible) from theburning of fossil fuels at asignificantly reduced levelcompared to HMA (Figure6). This would permitasphalt plants to be locatedin and around non-attainment areas such aslarge metropolitan areasthat have air qualityrestrictions.♦ Decreased fumes andodour. WMA produces lowerfumes and odour both atthe plant and the pavingsite compared to HMA. Thiswould also result in

improved working conditions atboth places.

♦ Decreased binder aging. Short-term aging of liquid asphalt bindertakes place when it is mixed withhot aggregate in pug mill ormixing drum. This aging iscaused by the loss of lighter oilsfrom the liquid asphalt bindersduring mixing at hightemperatures. It is believed thatthe short-term aging of the binderwill be reduced significantly

because the loss of lighter oilswill be less at relatively lowermixing temperatures. This mayenhance asphalt pavementdurability.

♦ Extended paving season. Byproducing WMA at normal HMAtemperatures, it may be possibleto extend the paving season intothe colder months of the year orin places located on high altitudessince the WMA additives orprocesses act as a compactionaid. Further by narrowing thedifference between compactiontemperature and ambient airtemperature the rate of cooling isdecreased. WMA may also betransported over longer distancesas compared to HMA with reducedloss of mix temperature in thehauling units. This advantageshould facilitate the Indian BorderRoads Organization (BRO) inconstructing asphalt roads in highaltitude and/or remote areas faraway from hot mix plants.

♦ Compaction aid for stiffer mixes.WMA additives and processesmay be used to improve the

compactibility of stiff mixes whenmix is produced closer to typicalHMA production temperatures.Smaller reductions in temperaturemay also be possible. There isextensive experience with the useof certain types of WMA with SMAin Europe.

♦ Increased amount of RAP.Research has shown that thepercentage of reclaimed asphaltpavement (RAP) can be increasedin WMA compared to HMA duringhot recycling.

♦ Generation of carbon credits forIndia. Developing countries likeIndia can earn CERs (CertifiedEmission Reductions) orpopularly known as carbon creditsunder the Kyoto Protocol iftechnologies such as WMA areintroduced and implemented.

At the present time a mix isconsidered warm mix in the US ifthe mix produced at the plant hastemperature exceeding 100ºC butsignificantly below that of a normalhot mix. WMA has a wide range ofproduction temperatures rangingfrom slightly over 100ºC to about20 to 30ºC below typical HMAtemperatures. WMA technologies arealso applicable to mixes made withpolymer modified asphalt binders.

WMA technologies can beclassified broadly as (a) those thatuse water, (b) those that use sometype of organic additive or wax, and(c) those that use chemicaladditives or surfactants.

Technologies which introducesmall amounts of water to hotasphalt binder, take advantage ofthe phenomenon: when water turnsinto steam at atmospheric pressureit expands in volume by a factor of1,673. This causes tremendousincrease in the volume of asphaltbinder which not only helps incoating the aggregate easily butalso lowers the mix apparentviscosity. Processes to introducewater into the asphalt binder consistof foaming nozzles, use ofhydrophilic material such as zeolite

or use of damp aggregate. Asphaltbinder temperature typically is thesame as that used for hot mixasphalt.

Technologies that use organicadditives or waxes lower the asphaltbinder viscosity above theirrespective melting points. It shouldbe ensured that their melting pointsare above the in-service pavementtemperatures during hot summersso that permanent deformation orrutting does not become a problem.

Technologies that use somechemical additive and /or surfactantsproduce a variety of differentmechanisms to coat the aggregateat lower temperatures.

It appears WMA technology isabout to take off in India. There isa need to incorporate WMAspecifications in MORTHspecifications.

Recycling ofBituminousPavementsRecycling of existing asphaltpavement materials to produce newpavement materials results inconsiderable savings of material,money, and energy. The specificbenefits of recycling can besummarized as follows:1. When properly used, recycling

can result in substantial savingsover the use of new materials.Also, the cost of haulage can beavoided if recycling is performedin place. The need for economicconsideration is felt now morethan ever, because of tighteningbudgets and ever increasing costof materials.

2. Recycling can help inconservation of natural resourcesby reducing the need for newmaterials. This translates tosubstantial savings in aggregateresources and demand forasphalt binder (bitumen),especially during supplyinterruptions. Even though theremay be an abundant supply of

aggregates, the distribution ofthese sources does not alwayscoincide with the location of need.

3. Recycled materials have provento be equal or even better thannew materials in quality. Hot mixasphalt (HMA) overlay on recycledbase is expected to perform betterthan an HMA overlay on theexisting surface, even though theyhave the same thickness,because the former cansubstantially reduce the potentialof reflective cracking through thesurface course.

4. Recycling can maintain pavementgeometrics as well as pavementthickness. The existing pavementstructure can be strengthened byrecycling without addingsubstantial overlays. In somecases, the traffic disruption islesser than that for otherrehabilitation techniques.

5. Recycling can save considerableamount of energy compared toconventional constructiontechniques. This factor is ofsignificant importance during anenergy crisis l ike the oneexperienced during the 1972 Araboil embargo.

Over the years, recycling hasbecome one of the most attractivepavement rehabilitation alternatives.With the continuous accumulationof performance data, field andlaboratory evaluations of recycledmixes, and with the simultaneousdevelopment of realisticperformance oriented guidelines itis expected that recycling willcontinue to be the most attractiverehabilitation technique.

Different recycling methods arenow available to address specificpavement distress and structuralneeds. A brief description of theserecycling methods follows.

The Asphalt Recycling andReclaiming Association define fivedifferent types of recycling methods:(1) Cold Planing; (2) Hot Recycling;(3) Hot In Place Recycling; (4) ColdIn-Place Recycling; and (5) Full

Depth Reclamation.Cold planing is described as

an automatic method of removingasphalt pavement to a desireddepth and restoration of the surfaceto a desired grade and slope andfree of humps, ruts and otherdistresses. This method can beused for the roughening or texturingof a pavement to improve frictionalresistance. Cold planing isperformed with a self propelledrotary drum cold planing machinewith the reclaimed asphaltpavement (RAP) transferred totrucks for removal from the job site.The resulting pavement can beused immediately by regular trafficand overlaid at some future time orleft as a textured surface.

Hot recycling or hot mixrecycling is the process in whichreclaimed asphalt pavement (RAP)material is combined with newmaterials, sometimes along with arecycling agent, to produce hot mixasphalt (HMA) mixtures. Both batchand drum type hot mix plants areused to produce recycled mix. TheRAP material can be obtained bymilling or ripping and crushingoperation. RAP at ambienttemperature when introduced inweigh hopper of the batch plant(Figure 7) or drum of the drum

plant is heated by superheatedvirgin aggregate. If the amount ofRAP exceeds 15-20 percent, asofter asphalt binder is used torejuvenate the aged asphalt binderin the RAP. The mix placement andcompaction equipment andprocedures are the same as forregular HMA. Typical RAP to newaggregate ratio varies from 10:90to 30:70 with a maximum of 50:50(drum plant). The advantages of hotmix recycling include significantstructural improvement, equal orbetter performance compared toconventional HMA, and capability tocorrect most surface defects,deformation, and cracking.

Hot in place recycling (HIR)consists of a method in which theexisting pavement is heated andsoftened, and then scarified or hotrotary mixed to a specified depth.New HMA or recycling agent maybe added to the RAP materialduring the recycling process. HIRcan be performed either as asingle pass or a multiple passoperation. In single pass operation,the restored RAP material iscombined with new material. Inmultiple pass operation, therestored RAP material isrecompacted first, and a newwearing surface is applied later. The

depth of treatment varies between20 to 40 mm (3/4 in to 1½ in). TheAsphalt Recycling and ReclaimingAssociation (ARRA) has identifiedthree HIR processes; (a) surfacerecycling, (b) repaving, and (c)remixing. In a surface recyclingoperation the existing asphaltsurface is heated and scarified to aspecified depth. The scarifiedmaterial is combined withaggregate and/or recycling agent.The mix is then compacted. A newoverlay may or may not be placedon the recycled mix. In the secondtype of HIR method, repaving, thesurface recycling method iscombined with a simultaneousoverlay of new hot mix asphalt(HMA). Both the scarified mix andthe new HMA are rolled at the sametime.

In the case of remixing, thescarified RAP material is mixed withvirgin HMA in a pug mill, and therecycled mix is laid down as asingle mix. The advantages of hotin place recycling are that surfacecracks can be eliminated, ruts andshoves and bumps can becorrected, aged asphalt binder isrejuvenated, aggregate gradationand asphalt content can bemodified, traffic interruption isminimal, and hauling costs areminimized.

In cold in place recycling (CIR),the existing pavement material isreused without the application ofheat. Except for any recycling agent,no transportation of materials isusually required, and, therefore,haulage cost is very low. Normally,an asphalt emulsion is added as arecycling agent. The processincludes pulverizing the existingpavement, sizing of the RAP,application of recycling agent,placement, and compaction. Theuse of a recycling train, whichconsists of pulverizing, screening,crushing, and mixing units, is quitecommon. The processed materialis deposited in a windrow from themixing device, where it is pickedup, placed, and compacted with

conventional hot mix asphalt laydown and rolling equipment. Thedepth of treatment is typically from75 to 100 mm (3 to 4 in).

The advantages of cold in placerecycling include significantstructural improvement, treatment ofmost pavement distress,improvement of ride quality,minimum hauling and air qualityproblems, and capability ofpavement widening.

Full depth reclamation has beendefined as a recycling methodwhere all of the asphalt pavementsection and a predeterminedamount of underlying material aretreated to produce a stabilized basecourse. It is basically a cold mixrecycling process in which differenttypes of additives such as asphaltemulsions and chemical agentssuch as calcium chloride, Portlandcement, fly ash, and lime, areadded to obtain ail improved base.The four main steps in this processare pulverization, introduction ofadditive, compaction, andapplication of a surface or awearing course. If the in placematerial is not sufficient to providethe desired depth of the treatedbase, new materials may beimported and included in theprocessing. This method ofrecycling is normally performed toa depth of 100 mm to 305 mm (4to 12 in). The advantages of fulldepth reclamation are that mostpavement distresses are treated,hauling costs are minimized,significant structural improvementscan be made (especially in base),material disposal problems areeliminated, and ride quality isimproved.

ReviewIn the sixties and early seventies,studded tires were used inGermany during wintertime. Thewear of asphalt surface coursesunder the spikes was extreme.Research and investigations on theperformance of surface courses ofasphalt concrete (AC) andgußasphalt verified that wear andrutting by studded tires wasincreased by:♦ high air void content of the surface

course,♦ low bitumen content,♦ inadequate quality and quantity

of aggregates.In the end of the sixties, theseresults were the starting point forseveral large companies of theasphalt paving industry to developspecific mixes which werepublished under different proprietarynames. Later, all these mixes werestandardized and called StoneMastic Asphalt or Stone MatrixAsphalt l ike in India (seeIRC:SP:79:2008).

In 1975, the use of studdedtires was banned. In the followingtime surface courses with asphaltconcrete and prototype SMA mixesshowed a different performance ofheavily trafficked higways: asphaltconcrete with a high bitumencontent was disposed to permanentdeformation, whereas asphaltconcrete with a low bitumen contentwas disposed to aging andpreliminary cracking. However underequal conditions both types ofdistress were not observed withSMA - surface courses. Practicalexperiences and observationsproved that SMA is a better mixthan asphalt concrete. Since highperformance highways, especiallythe “Autobahn,” have been an assetof the transportation-system, therehas been constant strive for betterpavements and asphalt mixes.Consequently, SMA has graduallyimproved by investigations, testsand feedbacks from highwayprojects. Finally in 1984, SMApassed the stage of a contractor`sproprietary product. It wasstandardized and became a part of

the German ZTV Asphalt (TechnicalSpecifications and Guidelines forthe Construction of AsphaltPavements), issued by the FederalDepartment of Transportation.

Years after the successfulapplication of the Stone MasticAsphalt principle in Germany, otherEuropean countries are using thisphilosophy also for heavy trafficroads. Now, many countriesworldwide have taken over thephilosophy of the Stone MatrixAsphalt.

The Philosophy ofThe SMA - ConceptThe philosophy of the SMA - conceptcan be summarized briefly asfollows:♦ High stability to permanent

deformation and high wearresistance by an excellent particleinterlock and a high content ofcrushed premium aggregates.

♦ Longevity and durability topremature cracking and ravelingby a very high content of bitumenand a void less mastic mortar

which fills the voids of the stoneskeleton and binds it together:high quality and quantity ofbitumen are prerequisite for a longuseful service life.

♦Stabilizing additives assurancesthe homogeneity (no binderdrainage) of the mix during themanufacturing, transportation andlaying. As a side effect, theyimprove the stability.

Summary: High quality and highquantity of bitumen and coarse gap-graded aggregates are theessentials for a long service life ofSMA.

SpecificationsTechnical specifications andguidelines for the construction ofasphalt pavements are always theconclusion of experience. In thefollowing, some requirements ofSMA and its ingredients areexplained. The European andGerman specifications for StoneMatrix Asphalt can be found at Table1 and Table 2.

AggregatesDouble crushed tough premiumaggregates of definite size,soundness, shape etc., e.g. max.20% of flaky and elongatedaggregates; all aggregates(aggregates, sand, filler) need tobe under a permanent qualityassurance, which is independentan from a third party.

Mineral typeThe mineral type is specified in theTL Gestein (technical deliverspecifications of mineralaggregates). The TL-Gestein isbased on the EuropeanSpecification EN 13043. Asminerals should be used granite,diabas, basalt etc. Limestone,sandstone and “soft” mineralsshouldn’t be used. Because of thelongevity of the SMA and the lowcontent of crushed sand, theminerals/aggregates must have ahigh resistance to polishing (highpolished stone value; PSV 48) andthey also need to have a goodaggregate abrasion value (LA 20).Furthermore, if available, the use oftwo different types of minerals canimprove the performance and skidresistance.

FillerUsually mineral filler (groundedlimestone) is used.

Sand100% of the sand fraction must becrushed.

GradationGap-graded: very high content ofcrushed coarse aggregates, seeFigure 2.

If you have no problems withthe aggregates used in asphaltconcrete, you will also have noproblems in the SMA-mixture. If youhave problems with the aggregatesused in asphalt concrete you willhave more problems using theseaggregates in SMA.

BitumenThe use of the particular bitumenquality predominantly depends onclimate and traffic conditions. Pavinggrade bitumen and polymermodified bitumen is specified byEuropean standard EN 12591 andEN 14023 (PmB).

significantly increased.The Stone Matrix

Asphalt is appropriatefor:♦ Highways♦ Federal roads♦ Rural roads♦ Urban roads♦ Airports♦ Industrial areas

There are nospecial regulations inthe EuropeanSpecifications 13108-5for the design of SMAsurface courses. Thechoice of SMA mixdesign is at thediscretion of the clientwhen preparing theRFP (requirements forpavement). For thehighway projects, SMAis the most favouriteand acceptableasphalt mix andtherefore - by

experience – it is used intensivelyfor these highway pavements.By the selection of SMA, there is astrong tendency to a smaller topsize, i.e. from 11 mm to 8 or 5 mmtop size aggregates, because ofthe following reasons:♦ Lower unit price per sq. m

because of smaller thickness isnecessary

♦ Less noise under traffic♦ Better skid resistanceBy the same reasons a SMA 16mm surface course is notstandardized in 16 mm SMA mixesof 16 mm and even larger top sizeare not used:♦ a larger top size requires a

greater thickness which means ahigher unit price per sq. m,

♦ larger top sizes generate moretraffic noise; but there is a strongdemand of public to reduce trafficnoise.

Mix DesignThere is no specific mix designmethod for SMA, but there are

Figure 2: Good coarse aggregate skeleton

AdditivesAccording to the specifications thefollowing additives are permitted:♦Cellulose fibers♦Polymers♦Artificial silicious material.

The selection of the additiveand its quantity is a part of theduties and responsibilities of thecontractor.

Reclaimed asphalt isn’t beingused for SMA; the feasibility hasnot yet been evaluated and

experienced. More requirements aregiven in Table two.

Range of ApplicationSMA is adequate and it isrecommended for any surfacecourse. It is especially used for allheavy traffic roads: SMA is muchmore economical (Long-life Asphaltpavements 2007, EAPA) thanasphalt concrete. Since thespecifications were introduced in1984, the use of SMA has

information sheets for initialsuitability tests on hot mix asphalt.

The steps of the evaluation ofan appropriate job mix formula(JMF) according to the informationsheet mentioned above are asfollows:a) In accordance with the RFP

(requirements for pavement) andwith respect to its experienceswith former JMFs, mixing, paving,performance during the time ofwarranty, and - last but not least -the price, the contractor selectsthe aggregates and the filler. withthe selected material (aggregates,sand, filler, additives) and on thebasis of the feedback from othersites and JMFs, a tentativegradation is chosen. But thereare requirements for abrasionvalue, polish stone value, freezing-thawing-test, etc.

b) Mixes with the requiredminimum asphalt content andwith three adjacent asphaltcontents are prepared.

c) Marshall specimen areprepared at 135/145 ± 5°C andby 50 blows on each side theMarshall tests are running for theevaluation of the air void contentwhich must range from 3 to 4 %by volume (i.e depending onGerman climate conditions). If therequired air void content is notachieved, the following alterationsof the tentative mix within theenforceable limits of the

specifications are recommended:♦ Change total content or contentof single sizes of crushedaggregates♦ Change filler content♦ Change mortar content

It has to be emphasized thatthe Marshall-stability and -flow arenot an adequate basis for the rightchoice and evaluation of the SMAjob mix formula.d) Drain-down test: Additives are

necessary to avoid drainage ofbinder from the coarseaggregates during mixing,transportation and paving.Therefore, a drain-down test mustbe performed for the evaluationof the appropriate and necessarycontent of the additive. TheSchellenberg Binder DrainageTest (Figure 3) is standardized inGermany and in the EuropeanUnion (EN 12697-18: Bituminousmixtures – Test methods for hotmix asphalt – Part 18: Binderdrainage).

On the basis of the mix designresults, the contractor decides onthe JMF and submits it to the clientfor his approval.

AdditivesAlthough fibers, polymers andsilicious materials are alsopermitted, cellulose fibers are usedvery extensively. By tests, trials andby experience, it was discoveredthat only the use of polymer is not

adequate to avoid segregation ofthe gap-graded coarse aggregatesand the high bitumen content. Theadditive has to be a bitumen carrier;polymer as a bitumen improver isnot sufficient. All SMA-JMFs withpolymers also had a lower bitumencontent than required or they hadadditionally fibers mixed in toachieve the requirements of eachcountry.Cellulose fiber shows no chemicalreaction with the bitumen and it isinert to mixing temperatures and itworks excellently. Because of theperformance of the cellulose fibers,the technical assistance of thesupplier and - last but not least -the relatively low price of the fibers,the usage and the market share ofthe different types of additives forSMA e.g. in Germany is as follows:Cellulose fibers 95%, the restmineral fibers and other additives.

MixingMixing and paving is neitherspecified in the specifications norin the RFP. Method and equipmentare within the assignedresponsibility of the contractor. Histechnical expertise andaccountability are essential.Drying of the unbound coarsematerial needs less heat than it isnecessary for standard asphaltconcrete (AC) and therefore the heatof the dryer must be reduced. Shortterm aging of the asphalt is verylikely when it is mixed with too hotcoarse aggregates. Drying of theminerals needs to be executed atsuch a temperature that the heat ofthe mix in the pugmill does notexceed 190°C.

The lower limit values are validfor the discharged asphalt mix atthe construction location;

The upper limit values are validwhen the asphalt mix leaving thepugmill or silo at the mixing plant.

Mixing times depend on the typeof plant.

In Europe, there are mostlybatch mixing pugmills. Drum mixingis possible by using bitumen coatedcellulose fiber pellets. As anexample, the time and sequence ofthe mixing process is demonstratedin Figure 4.

To enhance and improve thequality, the mixing time must beextended. Accordingly, the productionrate of SMA is lower than of asphaltconcrete: Quality has its price.

Exact proportioning of the fibersis important. A variation of the fibercontent ± 0.1% can result in avariation of the bitumen content ±1.0% without being recognizedvisually.

There are different possibilitiesto dose the fibers:

Figure 4: SMA mixing times with bituminous coated fiber pellets

♦ Dosing by big bag with automateddosing system (see Figure 5).

♦ Small packages – dosing byhand; this procedure needs muchmanual labor; it is obsolete, butstill practiced (see Figure 6).

According to the specifications,quality control by the contractor isalways necessary and required.Samples for quality control are tobe taken, i.e. every 500 tons.

Additionally and as a general rule,a quality assurance of the mixingplant by an independent third partyis required.

PavingPaving and compaction procedureis similar to every standard asphaltFigure 7.♦ Trucks must be covered until the

♦ Although the asphalt content ofthe SMA is very high, a tack coatis recommended to ensure andimprove the bond between thelayers.

♦ The temperature of the SMA inthe road paver should be at least150 (140)°C.

♦ An adapted pre-compaction ofthe asphalt paver is useful andshould be achieved.

♦ Compaction should be startedas soon as possible and theroller should move as close tothe paver as possible. Steelwheel rollers of approximatelyeight to ten tons for compactionare necessary. Vibrating shouldbe executed mostly two or threetimes. There is a hazard of mortarenrichment on the surface, ifusing too much vibrating rollerpasses. The consequence is avery low initial skid resistance.Vibrating is not advisable on thinlayers of approximately less than25 mm thickness and at layertemperatures under 100°C, seeFigure 8. Since sucking up of themortar is very likely compactingwith a pneumatic roller can be ahazard.

♦ Because of the high asphaltcontent, the initial skid resistancecan be low and it can causesafety problems on high traffichighways. Therefore, a surface

IntroductionConcrete Roads were first built byRomans (300 BC – 476 AD). Theywere quite innovative in theconstruction with the use ofinnovative materials viz., use of‘Pozzolana’ cement from the villagePozzouli near Italy, horse hairs asfibres in concrete, admixtures intheir primitive form (like animal fat,milk & blood). These roads,scientif ically designed andconstructed had a long life and thuslead to the adage ‘all (concrete)roads lead to Romel.’

Portland Cement Concrete(PCC) overlay on an existingbituminous pavement is commonlyknown as White topping. Theprincipal purpose of an overlay iseither to restore or to increase theload carrying capacity or both, ofthe existing pavement. In achieving

this objective, overlays also restorethe ride-ability of the existingpavements which have sufferedrutting and deformations, in additionto rectifying other defects such asloss of texture. In our country,bituminous overlays have beenpopularly constructed in the pastmainly due to abundant supply ofbitumen, its amenability to stageconstruction and manageable trafficconditions, in terms of volume andaxle loads in addition to the comfortlevels of construction methodsamong engineers. It was alsomaking economic sense to makebituminous pavements as it wasrelatively cheaper. In recent timesall these advantages are reversedviz., petroleum industry is usingrefined processing technologyleading to reduction in theproduction of bitumen leading toincreased imports, favourable cost

economics of cement concrete andrapidly changing traffic scenario (interms of volume as well as axleloads). In addition, rapiddevelopments in concrete materialtechnology and mechanization (bothin concrete production & its laying)are favouring concrete overlays asa sustainable option. In recent timesPPP (Public-Private Partnership)models are becoming popular inroad construction shifting the focuson selection of overlays based onlife-cycle costs rather than initialcosts. India is currently producingabout 240 million tonnes of cementand cement industry is quitematured and equipped to meet thechallenges in terms of variousgrades of cements as well as highquality blended cements suitablefor making Pavement QualityConcrete (PQC).

White Topping

Overlay Solutions forRehabilitationType of overlays is chosendepending upon the condition ofthe existing pavement. Bondedoverlays are preferred when thecondition of existing pavement isgood and the design will ensurethat the thickness of overlay isrelatively less. This is due to thefact that the pavement systembehaves as a composite structure,utilizing the flexural strength offlexible pavement as well. In casethe pavement is alreadydeteriorated, it can only be regardedas a base; to separate it from theconcrete overlay (in order to avoidreflective cracks), a separation layeris provided.

Concrete overlays have beenused to rehabilitate bituminouspavements since 1918 in USA.There has been a renewed interestin whitetopping, particularly on ThinWhite Topping (TWT) and Ultra-ThinWhite Topping (UTWT) overConventional White Topping. Basedon the types of interface providedand the thickness of overlay,classification is as follows:i) Conventional White topping –

which consists of PCC overlay ofthickness 200 mm or more,which is designed & constructedwithout consideration of any bondbetween existing overlay &underlying bituminous layer(without assuming any compositeaction).

ii) Thin White topping (TWT) – whichhas PCC overlay between 100 –

200 mm. It is designed eitherconsidering bond between overlay& underlying bituminous layer orwithout consideration of bond.High strength concrete (M 40 orhigher) is normally used to takecare of flexure requirement.Joints are at shorter spacing of0.6 to 1.25 m.

iii) Ultra-Thin White topping (UTWT)– which has PCC overlay of lessthan 100 mm. Bonding betweenoverlay & underlying bituminouslayer is mandatory. To ensurethis, the existing layer of bitumenis either milled (to a depth of 25mm) or surface scrapped (with anon-impact scrapper) or gentlychiseled. Joints are provided ata spacing of 0.6 to 1.25 m.

Advantages of Whitetopping♦ Reduced thickness – due to

thickness of overlay remainingconstant for over 2 decades.

♦ Fast-Track construction – makinguse of innovations in concretetechnology & batch mixing,concretes can be designed tohave 3 –days’ compressive (&

flexural) strength, so as to openthe road for traffic within 5 daysof construction.

♦ Reduced maintenance – as theconcrete overlays live for over 2decades, with least maintenance.

♦ Cost-effective compared to asphaltoverlays – when Life Cycle Costis taken into consideration.

♦ Improved service life – with betterriding quality, improved fuelefficiency of vehicles.

♦ Little pre-overlay repairs♦ Improvement in safety in view of

the increased reflection of light –particularly on city roads, it wouldsave 24% less electricitycompared to flexible pavements.

Improving the environmentalbenefits – as concrete roads aremuch greener and less polluting.

TechnologyDemonstrationProjectIn India, concrete overlays onexisting flexible pavement (whitetopping) have been constructed inrecent years in Mumbai, Nagpur,Indore among other places. InSouth India, several new concreteroads were constructed during thelast century which have givenexcellent service for over fourdecades, the examples being theBangalore-Mysore road constructedby the then Maharaja of Mysore, thecoastal roads in Kerala etc. Due tolack of experience and expertise inwhite topping, these roads wereconverted to flexible overlays inrecent times.

White Topping

With a view to familiarize with the advantages ofwhite topping, a Technology Demonstration Project wasundertaken in Bangalore jointly by the Bruhat BangaloreMahanagara Palike (BBMP), Task Force for QualityAssurance, Govt. of Karnataka and Cement Manufacturers’Association. The objective of this project was todemonstrate the advantages of white topping by makinguse of the advances in construction equipments andmethods.

Characterisation of the existing flexible pavement onthe trial stretch on Hosur Road in Bangalore yielded thefollowing data.

Design of Pavement and ConcreteMixDesign of the overlay was carried out using Westergaard’sEquation and warping stress as per IRC:58 -2002 andIRC: SP: 76 – 2008. Total stress (including temperaturestress) was obtained as 30.83 Kg/cm2 and correspondingflexural strength requirement was 4.7 MPa. Design wasdone by M/s L.R. Kadiyali & Associates, New Delhi.Thickness of white topping was 150 mm.

Concrete mix design was arrived at by evaluating trialmixes and the design mix was arrived at with a cementcontent of 430 kgs, fly ash – 30 kgs, with a w/c ratio of0.283, achieving a slump of 40 – 60 mm at site.

Details of ConstructionIn order to achieve the desired advantages of concreteroads, three essential conditions need to be satisfied.i) Production of concrete in a RMC plant or in a dedicated

batching plant.ii) Using either fixed form or slip form mechanical paversiii) Strict quality control at site including testing of fresh,

hardened and extracted specimens of concrete andtests on pavement quality.

In this project design and production of concrete wascarried out by UltraTech RMC; Fixed form paver providedby M/s Allen Buildwell Pvt Ltd., was used. Quality controlat site and testing were jointly done by the TechnicalServices team of UltraTech and M/s Civil Aid Technoclinic(P) Ltd., Bangalore.

Salient features ofConstructioni) Surface preparation: In case of

TWT, bond between PCC overlay& existing bituminous pavementis atleast partly desirable; in caseof UTWT, effective bond isessential. To ensure this any ofthe following method can beadopted.♦ Milling the existing bituminous

surface to obtain a uniform surface.Milling can be used to removesurface distortion like cracks inthe top portion and adjust crossslopes. Thickness of millingusually is in the range of 25 to 50mm.

♦ Surface scrapping is carriedout on bituminous surfaces whichare quite hard. This can be for adepth of 10 mm and carried outwith tools which have vertical

impact control, so that the sub-grade is not damaged.

♦ Chiselling of the surface atregular intervals, if the existingsurface is hard.

The minimum thickness ofexisting bituminous pavement(excluding the milled/scrappedthickness) shall be 75 – 100 mmto ensure a reliable & strong base.ii) Profile correction is carried out

with the objective of filling existingpotholes, ruts and wide cracksand also to ensure a level surfacefor resting the pavement. Profilecorrection and correction ofcamber can be carried outtogether with a thin bituminousleveling course or with dry leanconcrete (DLC).a. If the existing road surface is

good & only a few localizedpotholes / cracks exist, they canbe repaired with a bituminous mix

before concreting is done.b. If potholes/ cracks are wider

than 3 mm, they have to be treatedwith bituminous emulsion, slurryseal after trimming them to shapeand cleaning out loose fragmentswith compressed air. Milling of theexisting surface also addressesthis problem.

iii) Laying of PQC is quite similarto the construction of newconcrete pavement. As mentionedearlier, concrete should be madeeither in an RMC plant or in aweigh batching plant. Use ofeither fixed form pavers or slipform paver machines is anessential ingredient for getting agood quality pavement. In thecurrent project, a fixed form paverwas used with a fixed sideformwork (steel channel boxsection) with 16mm diametersteel rods of 1 m length as tie

within about 8 to 10 hours ofpouring concrete. These jointsare sealed with high qualitysealant (either bitumen or polysulphides) to prevent moistureand incompressible infiltrationinto the overlay system.

vii) To ensure effective load transferacross the longitudinal segmentsas well as transverse constructionjoints, tie bars and dowel barsare provided.

Test ResultsStrict quality control not only duringmix design and production ofconcrete, but also testing for qualityat regular intervals (for every 50

cum of concrete) was carried out.These tests included:

♦ Tests conducted on freshconcrete (slump test at site)

♦ Tests on hardened state(compressive strength of cube &cylinder specimens for 1, 3, 7 &28 days), split tensile strength,flexural strength of concrete beams

♦ Fatigue and abrasion tests onpavement quality (results awaited).

♦ Test on extracted specimensof concrete (core tests) would beconducted to assess the longterm performance of concrete.

All the above tests areconducted by Civil Aid Technoclinic(P) Ltd., Bangalore and the resultsobtained so far are tabulated. Theroad was opened for traffic after 5days of curing.

ConclusionsDue to advances in the area ofmechanization and fast trackconstruction, concrete roads andwhite topping provide a sustainableas well as cost effective option forpavement construction. Thistechnology demonstration project inBangalore has evoked positiveresponse from people across thespectrum viz., technical consultants,construction industry, academic &research institutions. TheGovernment of Karnataka, BBMPand other civic agencies have comeforward to adopt this technology.On behalf of the cement industry,

iv) Finishing of the surface is mostlyachieved by the paver itself. Butto achieve uniform finish, a simplehand operated bull float is usedwhen concrete is still in its freshstate. After the bull float operation,uniform surface texture isprovided by using steel wirebrush.

v) To avoid evaporation of surfacewater from concrete surface(which leads to plastic shrinkagecracks), wax based curingcompound is sprayed. As anadditional measure, plasticsheets are spread over thepavement surface till normalcuring process starts.

vi) Contraction joints areprovided by cutting groves (fora depth of one-third of thedepth of white topping, 150mm in this case) at a spacingof 1.2 m in longitudinal aswell as transverse directions.The joints are cut usingelectrical grove machines

Raising environmentalconcerns, fuel costs andthe steadily declining

natural resources affect not only thecost of asphalt mixes per se, but isforcing the industry to go green.Today, every professional in the fieldunderstands that going green isnot just a fashion statement oreyewash, but it is posing a verycrucial question about survival. Itis impossible to be profitablewithout being green.

Sustainability is no longer a‘nice to have’ accessory forbusiness – it is an essentialrequirement, and must be built intoall our goals and policies. Thebenefits of working responsibly andsustainably are immediate as wellas long term. Many of ourcustomers are looking for us todemonstrate publicly ourcommitment to working sustainablyand report on performance.

There are numerous methodsthat the road building industry hasadapted to reduce their energyconsumption and to be morecarbon friendly. The urgency is sogreat that at each level starting formequipment design to production andlaying techniques, focus has to beconsistently placed on reducing thecarbon emission.

This technical note describesthe various techniques availableand presently being implementedworld over for production of Lowenergy asphalts or Carbon friendlymixes. Production techniques forwarm and half warm mix asphalteither use chemical or mechanicalsolutions. The modifications madeto existing plants in order to producelow energy asphalt by chemicalmethods (additives) are minor,whereas more significantmodifications must be made tomechanical methods (foam bitumen

or sequential coating). This papercovers the possible solutions andprovides A summary on itsadvantages.

BeginningsIt is highly unlikely that we can putan exact date on the emergence ofthe concept. Since the mid 20thcentury, and the industrialdevelopment of hot mix asphalt(HMA), engineers have had a cheapenergy source at their disposal withthe environment only a minorconcern. Good Practice stipulatedthat the asphalt had to be around150°C. Since bitumen ishydrophobic, coating is that mucheasier when the aggregates aredry. The European productionstandard nevertheless states thatthe maximum residual watercontent of HMA is 0.5%. In the1970s, when TSMs (dryer drummixers at parallel flow) developed,

excellent results at 130°C werenevertheless noted, with a residualwater content of 1%, especiallyduring compaction.

Coating attempts with foambitumen subsequently developed inthe 1990s in the UK, South Africa,the Netherlands and France. Theconcept of warm and half warmmix asphalt was first mentioned inthe late 1990s, particularly byJENKINS [1], and alternativetechniques to foam bitumenflourished in all countries, notablyScandinavia, with sequential coatingtechniques using several types ofbitumen.

A typology of the mixes wasofficially described by Dr. JacquesBonvallet from FAYAT Group in 2000[2], with reference to the heating anddrying energy used during theprocess. The 100°C border iswidely discussed and there are twoschools of thought: one thatrecommends staying shy of the100°C mark for the sake of makingvaporisation energy savings (1/3 ofthe total energy), and the otherwhich recommends vaporisingwater while remaining within the110 to 130°C range, which alsosaves around 30%.

The last decade, in Europe atleast, has been characterised by

an increase in methods – some ofwhich are experimental. We haverecently been seeing a segregationof processes that are becomingsimpler and can be split into twofamilies:- chemical processes in which the

use of an additive makes itpossible to reduce the bitumenviscosity and perform high-qualitycoating;

- mechanical processes, whicheither involve sequential coatingor coating with foam bitumen.

We can suppose thatprocesses will become moreindustrial and develop considerablyover the coming years. In Francethey certainly accounted for some500,000 t in 2009 for 40 milliontons of asphalt; the room forprogression may be significant, butcertain.

Low energyproductionOne trend that seems to beemerging is the production ofwarm mix asphalt around120/130°C using bitumenwith additives. The hypothesesput savings at between 10and 20%.

Without recycling anddepending on the humidity

(ignoring any water additions), thecalculated consumption levels of theburner are as follows:

Some techniques are based ontemperatures below 130°C, andeven below 100°C. Reductions of40 to 50% in energy consumptionor emissions are claimed,especially during low-temperatureand/or low energy processes (LEPand LTP) [3], [4].

Several studies conductedjointly by inventors and the FrenchPublic Works Research Laboratoryare under way, some equipping aproduction plant so as to be ableto compare calculations to the testdata.

Chemical solutionsThese solutions require theinjection of either solid or liquidadditives into the mixture. Thesecan be incorporated into thebitumen or during the mixing stage.

In all cases, the plant must befitted with systems for storing,transporting and metering additives(flowmeter).

All of these processesimplement coating of the samequality as HMA, whereas understandard conditions, the bitumenviscosity would not allow the

aggregates to be properly coated.Adding water to monitor the watercontent is always necessary, and itis water that bestows workabilityand therefore the aptitude forcompaction.

Mechanical solutionsThese solutions are perhaps morecomplex and based either on theprocess using foam bitumen,injected with a system of injectorsplaced above the mixer, or on thecreation of foam in the mixer over avery short timeframe in dispersed

form. To do this, the companyapplies a sequential process,bringing the water and hot bitumeninto contact in the mixture.

Several methods co-exist – theinjection of foam directly by injectorseems simpler and less expensiveto implement, for less investment.

Fairly exhaustive laboratorystudies were published in 2008 onthis matter [5].

The peripheral equipmentrequired is fairly simple and shownin photograph 3 and 4.

The Ultimatesustainable mixproductionThe combination of low energy withrecycling is a worthwhile solutionlikely to be pushed to the extent ofobtaining high recycling levels. Itseems to us that the most suitableequipment and – in all cases – themost flexible for meeting theseobjectives is that which comprisestwo drums and an external mixer,like the RMS TSR in photograph 5.

Since the energy consumed forthe RAP on the one hand and thevirgin materials on the other iscontrolled in two drums, there istotal independence and optimisedrational management.

Advantages of Lowenergy mixproduction♦ T° decrease by 30 or 40°C♦ Substantial reduction in CO2

emissions♦ Combustible savings: 15 to 30%♦ No bitumen vapour emissions♦ Hot-mix easy-to-use♦ Possible high recycling rate

Marini’s global experience andexpertise in the field allowed themto anticipate the raise of thesetechnologies in India and hencethe plants supplied in India arealready configured with the requiredaccessories and processautomation, making production ofthese energy saving mixes instantlyadaptable in India.

Comment on warmmix asphaltcompactionThe influence of the temperatureon asphalt workability has longbeen known, and summarised inthe Table below from themanufacturer BOMAG. We canparticularly see that the necessaryenergy for obtaining an equivalentcompaction between 120°C and150°C is multiplied by 4.

In reality this means a highercompaction requirement, eitherthrough more passes or by using amore powerful compactor.

The solution adopted in Europeto monitor the subject firstly involvescontrolling the residual water –which improves workability andtherefore compaction in a smallamount – and secondly usingvariable-energy compactorsbelonging to the category of so-called smart compactors, such asAsphalt Manager [6].

ConclusionWe are going through a pivotalperiod in which the significant rise

The challengingpart of the operation is to add andmix the special chemical /sequence in the already fullyautomatic process of asphalt mixproduction.

The need has never beengreater for engineeredstrategies to preserve and

maintain the nation’s pavements.With shrinking budgets, everincreasing traffic volumes and loads,and the critical emerging focus oninfrastructure sustainability, highwayagencies and local roadconsultants and municipal bodiesare being asked to “do more withless” in managing their pavementnetworks.

Agencies need to be proactive,sustainable pavement mountainousand rehabilitation strategies thatlast longer and at reasonable costs.In many situations, concreteoverlays or similar to “Thin WhiteToppings” represent suchstrategies. They offer cost effective,versatile, short-and long-termsolutions for the full range ofconcrete, asphalt, and compositepavements needs. In addition, theycontribute to more sustainableconstruction practices by preservingpavement service for severaldecades beyond original service life.

Many concrete overlays havebeen in service for decades,extending the life of the originalpavement structures for 30 years ormore! Because concrete distributesthe traffic loads over a wide area,the underlying pavement does notexperience highly concentratedstresses. As long as the originalpavement remains stable anduniform, a concrete overlay can beplaced, replaced, or recycled asneeded for maintenance and orrehabilitation cycles.

In this manner, the concreteoverlay systems can be sustainablefor 100 years or longer. Rather thanremoving and reconstructing on yearon year basis adding top coatswhich give away within weeks offacing rains or heavy trafficconditions, a concrete overlayeffectively returns its originalinvestment within 2-3 years of thedifferential cost and does away withyearly maintenance and suffering tothe general public and saving a lotfor nations spending.

There are several genuinebenefits of the Concrete Overlays:1) Concrete Overlays consistently

provide cost effective solutions.Rupee for Rupee they are one ofthe most effective long-termmaintenance and rehabilitationoptions for the existing pavementswith distress.

2) Concrete Overlays can beconstructed quickly andcontinently as

a) The existing pavement does notneed to be removed.

b) Simple operations of surfacemilling or scarifying is enough for“bonded overlays”

c) Few or no pre-overlay repairsare necessary or even desirablein most cases.

d) Concrete Overlays are placedbetter using TRTP Fixed Formwith Gang Mounted Vibrators orsuch machines with normalconstruction practices.

e) Many concrete overlays can beopened to traffic within 3-4 daysto traffic from date of placement.

f) Accelerated construction practicescan be used throughout thenormal construction season.

3) Concrete Overlays are easy torepair.

4) Concrete Overlays are durablerehabilitation tool and most costeffective option

5) Concrete Overlays can survive inand of themselves, as completepreventive maintenance or rehabsolutions, or can be used in

conjunction with spot repairs ofisolated distress.

6) Concrete Overlays enhancespavement sustainability byimproving surface reflectance,increasing structural longetivityand enhancing surface profilestability.

New Approaches

OverviewA 39 kilometer toll motorway wasconstructed on budget (A$2.5 billion)and five months ahead of time. Itwas opened in June 2008. Thisproject involved 17 interchanges, 88bridges and twin three lane, 1.6 kmtunnels. It has three lanes in eachdirection for 33 km and two lanesin each direction for 6 km. EastLinkconnects the eastern suburbs ofMelbourne and was delivered undera Public Private Partnership (PPP)arrangement by Connect East (listedon the Australian Stock Exchange)for the Victorian Government agency,Southern and Eastern IntegratedTransport Authority (SEITA). Projectdevelopment was undertaken bytwo of Australia’s largest contractingorganisations, Thiess and JohnHolland, in a joint venturearrangement.

This paper describes theuniqueness of the project,construction practices and theworking relationship with ownersand contractors that led to asuccessful outcome. This projecthas set new standards in design,construction speed, safety,

environmental impact, communityengagement and significantlyenhanced the urban amenity of thecorridor.

BackgroundThe road reserve for this corridorwas planned in the early 1960’s.Environmental impact statementswere developed and consulted withthe community living along thecorridor in the 1990’s. As Melbournecontinued to expand, theconstruction of the Motorwaybecame imperative. Workcommenced in March 2005 andwas completed in June 2008. Anoverview of the motorway section isbeing presented in Figure 1.

Performance BasedSpecificationsRight at the tendering stage,considerable thought was given toencourage competition in the privatesector to achieve the best outcomefor the Motorway. One of the keyelements was devising theperformance based specificationsthat would make it clear what wasneeded without specifying how it

should be achieved. Interestingly,the document produced was afraction of the size of a normalspecification, yet spelt out theState’s requirements. It had settargets such as a 100 year designlife for structures.

The specifications provided forthe road to fall within a certain routeenvelope but the exact alignmentwas variable; the shape of the

interchanges was open to variation,and the pavement had to performto a certain standard yet its make-up was not prescribed. Urbandesign had to be a part of the mixand the bids had to show that theyreflected community expectationsalong the route. The requirement ofthe tolling system was that it had tobe fully electronic and it had to beinteroperable with other electronictoll roads in Australia. Toll levelswere not prescribed with the onlyrequirement deemed that escalationhad to match movements in theConsumer Price Index (CPI) withchanges being applied annually.Both design and construct contractswere self-monitored by QualityAssurance (QA) procedures andchecks as work progressed.

The IndependentReviewerThe Independent Reviewer (IR) wasappointed jointly by the Governmentand the Concessionaire. The IR’srole involved a general overview andreasonable checking in order to besatisfied that the various detailedchecks and monitoring processeswere carried out correctly and, inorder to ensure compliance withthe design constructionrequirements. This organisationreported jointly to the twoemployers, ensuring impartialitybetween the two client sides. Alldesign and construction informationdeveloped by the contractor had tobe provided to the IR who had theresponsibility to certify completionbefore the road could be opened.

WorkingArrangementsFor the processes to be efficient,tight timelines for makingcomments were agreed by allparties to ensure the contractor wasnot unduly held up waiting forresponses. This arrangement wassuccessful as effective workingrelationships and flexibility were

established between the peopleworking on the project (thecontractor and the two clientbodies). An electronic trackingsystem was implemented andimproved the efficiency of thedocumentation flow.

Another efficient processimplemented was that constructionitself was subjected to QualityAssurance (QA) processes. Thecontractor was responsible forauditing and guaranteeing its ownsystems according to appropriateQA standards.

The ConstructionChallengeThe Tunnel: The construction of the$600 million twin tunnels was acomplex operation. The diametersof each tunnel exceeded 16 meterswith special ventilation buildings atthe exits. These buildingsincorporated large fans to capturethe air leaving the tunnel and thecar exhaust contained in it. Theexcavation was undertaken by fourlarge machines known as roadheaders. These have a rotatinghead with cutting teeth at the endof a pivoting boom for cutting awaythe material at the heading of thetunnels, Figure 2.

The tunnel was also fully“tanked.” This means that it wasmade watertight, rather thanallowing water to trickle in the tunneland then draining it out. This wasdone by having a circular crosssection for the tunnel and using adrainage blanket and waterprooflining, Figure 3. An overview of thetunnel is presented in Figure 4.

The Bridges: For most of the88 bridges, pre-cast reinforcedconcrete units were used for speed,quality and economy. In the case ofan operational railway line whichoverpassed the new road, theconstruction schedule was plannedin such a way that it was closedonly for a very short time. This wasachieved by first, installing thefoundations and final columns ofthe new bridge and then thecrosshead supports for the bridgesuper structure. The foundations ofthe four-span bridge comprised 1.8metre diameter bored concretepiles which could be installedoutside the train “envelope,” Pairsof the piles at each of three pierpositions and for the abutmentswere put in through the existing railembankment. They went into theground as support but stood free inthe top few metres once the groundwas excavated around them,

forming the columns of the bridge.The super structures, complete withnew rail tracks for the new railwayoverpass, was built alongside theoperational railway on theextensions of the crossheads.Times for completion issimultaneously with the bridgestructure. The super structure wasslid in after a weekend so that therailway was ready for the peak railoperation at the beginning of theworking week.

A 500 tonne mobile crane wasused for lifting heavy crossheads

and beams for bridge constructionthroughout the project. Some of thebridges including the rail bridge overthe motorway are shown inFigure 5.

Use of precast segments forconstruction: The contractordecided to establish a specialprecasting yard for the manufactureof pre-cast reinforced concreteelements. During the two yearoperation, the yard produced over23,000 pre-cast units, of a widevariety from bridge beams andparapet panels to assorted noise

wall panels, retaining wall fasciaunits and bridge pier sections. Thisensured tight quality control of allstructural elements and other pre-cast products and achieved a betterresult than that normally achievedby onsite casting. Most of the bridgebeams were Super Tee Beams, aV-shaped trough with a flat baseand flat projections at the top. Thespecial design was developed inAustralia and is now widely usedon major road projects. A keyadvantage of the design is that itcan be produced in various depthsfor different span lengths.

The tolling system: A multi-lanefree-flow Electronic Toll Collection(ETC) system was used. Therecognition by vehicles is automaticthrough electronic tags mountedinside the vehicle which are notrequired to slow down or stop as

Noise walls: Over 13,000 noisewall panels were installed. Thesections of noise walls weredifferent in shape and colour toimprove the visual appearance andbetter integrate with the surroundingenvironment and look as natural aspossible. Typical wall panels,including transparent sections, asshown at Figures 7 and 8 weremanufactured precast at the precastfabrication yard.

Road construction: Theconstruction work involved threelanes in each direction for 33 km,two lanes in each direction for 6km. This involved over 7 millioncubic metres of earthworks, 1.1million tones of asphaltic concrete,and 380,000 cubic metres ofconcrete. Asphalt laying was a highlycoordinated large scale logisticsexercise in its own right duringconstruction (Figure 9).

Concluding RemarksEastLink has proven to be one ofthe most successful toll roadprojects in Australia delivered as aPublic Private Partnership. Thirtymonths after opening, traffic growthis continuing at an incredible 10%per annum and neighbouringcommunities are praise worthy ofthe delivered outcomes.

Key success factors includedclarity in contractual documentationand understanding of the roles of

Along its 39 km lengthEastLink has 13 tolling points eachwith two gantries (Figure 6). Thistolling system has the ability tohandle 4.5 million vehicle passages(transactions) per day. The twingantries also enable vehicledetection systems to recordregistration plate details shouldvehicles not be equipped with theelectronic tag. Video tolling is alsopossible.

Concrete Additives

IntroductionMicro Silica is a mineral composedof ultrafine (fineness in the rangeof 15,000, m2/kg) amorphous, glassyspherical particles of silicon dioxideproduced during manufacture ofsilicon or ferro silicon. The averageparticle size is less than 0.5μmeaning that each microsphere ofsilica fume is about 50 timessmaller than an average cementgrain particle. The ultrafine particlesof micro silica fill the gaps betweenthe cement particles thereby helpingto fill the micro voids in the freshconcrete. These particles also actlike ball bearings and make theconcrete more cohesive. Earlier itwas a common practice to usemicro silica in slurry form in orderto ensure uniform distribution ofmicro silica in the matrix. However,there were many issues faced atsite in introducing silica fume inslurry form.

Issues faced earlier while usingsilica fume (SF) in slurry form:♦ Separate plant has to be set up

for converting silica fume intoslurry form.

♦ Setting of plant involved anadditional capital investment.

♦ The pot life of SF slurry is in therange of 30 to 40 minute, so ithad to be used within short spanof time.

♦ Traffic Jams delayed themovement of transit mixer andsometimes led to dosing of slurryeven after the lapse of pot lifeperiod.

♦ If slurry is not used within pot lifeperiod, the interaction betweenwater and silica fume particlesbrings down the effectiveness ofsilica fume.

♦ In Metro cities, it might be difficultto allocate an additional land toset up separate unit for silicafume slurry production.

As such use of silica fume indry form is considered the mostsuitable and convenient system.However, the effect of sequencingof dosing of micro silica on concreteslump and strength properties (at 7and 28 days) need to be studied.To study the impact of dosing of drysilica fume, experiments wereconducted in the laboratory with two

different dosing sequences and theresults were compiled.

Sequence of Micro silicadosing in dry form in theconcrete mix:A. General Practice:It has been observed that at mostof the batching plants, the variousingredients of concrete and microsilica are loaded in mixer in thefollowing sequence:1) Coarse Aggregate and Fine

Aggregate2) Cement & Micro silica + Additives

(Fly ash / Slag)3) Mixing of (1) & (2) for approx 30

sec4) Water & Chemical Admixture5) Mixing for another, approx 30 sec6) Unloading the mix

B. New Practice explored forexperiment.

It was decided to explorepossibility of changing the dosingsystem of micro sil ica whilekeeping the mix design proportionsame for all the ingredients and tostudy its effect on slump andcompressive strength of concrete.

Effect of

S.B.Kulkarni - AVP, TechnicalServices & Hemendra S,Manager, Technical Services.UltraTech Cement Ltd.Mumbai.

Silica fume has been successfully used in production of high performanceand high strength concrete for the past couple of years. The benefits ofusing silica fume for enhancement of durability and improvement in themicrostructure of concrete are already well established through variousresearches and other developments. Few years back, it was a normalpractice to introduce silica fume in the concrete mix in slurry form.However, currently silica fume is dosed in dry form at most of the batchingplants. In this paper, an effort has been made to study the effect of dosingsequence of silica fume in the concrete mix in dry form, on the slump andstrength characteristics of concrete.

It is interesting to see that inTrial A & B the quantity of variousingredients is same, that includesquantity of water & plasticizer used.Normally, the slump increasehappens either by increase in thequantity of water or plasticizer orboth. But in this case, it is seenthat without changing the mixdesign proportion or adding extraquantity of water / plasticizer theslump for trial B has increasedbetween 47% and 78% just bychanging the sequence of dosingof silica fume (as given in Table 2).ii. Compressive Strength testresult:a) Accelerated Curing Test cuberesults (Conforming to IS 9013 –1978 - Reaffirmed 1999)

As mentioned above in thearticle, concrete cubes were testedby using Accelerated curing testmethod and results were tabulatedas mentioned in Table 3. It is seenthat for Trial A, the anticipated 28days strength was 43MPa, whereasfor Trial B it was 45.56MPa. In thiscase also, the change in sequenceof micro silica dosing has resultedinto increase in accelerated curingtest result value for Trial B by 5.95%.

b) Concrete cube results (as perIS 516 – 1959 - Reaffirmed 1999)Concrete cubes (150x150x150mm)were casted, cured and tested for3,7 & 28 days compressive strengthas per standard procedure. FromTable 3, it is seen that for Trial Athe 3, 7 & 28 days strength wasnoted as 24.58MPa, 31.76MPa &40.16MPa respectively, whereas forTrial B the compressive strengthwas noted as 27.87MPa, 37.29MPa

& 45.66MPa respectively. It is againinteresting to note here also thatthe compressive strength for 3, 7 &28 days for Trial B have increasedby 13.38%, 17.41% & 13.70%respectively as compared to testresults of Trial A. Here also exceptfor change in dosing sequence ofmicro silica no other changes weremade in the mix.

Conclusion♦ It can be seen that introduction

of micro sil ica in the miximmediately after adding coarseaggregates and then mixing thesame for 90 sec, has changedthe test results considerably bothin terms of slump andcompressive strength.

♦ The test results show that withoutadding additional water orplasticizers the slump valueshave enhanced by 47% to 78%and the compressive strengthvalues have enhanced by 13% to17%.

♦ The results are very encouragingas increase in slump values canfacilitate reduction of plasticizerdose & enhancement incompressive strength can facilitatereduction in the cement contentthereby leading to optimisation inthe cost of concrete mix.

♦ It is felt that at construction sitethe Quality Managers shouldconduct similar trials based onthe findings of the above referredarticle and try to get best benefitin terms of additional retention ofslump or reduction in theplasticizer dose resulting in easein placing, compaction & finishingof concrete, reduced honey comb

and also optimization of theconcrete mix design cost withoutspending extra penny for thesame.

♦ It is hoped that the contents ofthe article would give furtherguidance to Quality Managers forexploring the benefits of changingthe dosing sequence of microsilica, to their full advantage.

Alternative Material

IntroductionTraditionally, we are using burnt claybricks for construction. It is a clayproduct which proved its importancesince the dawn of civilization. Forproduction of bricks, we are usinggood plastic clay as primary rawmaterial. This clay is often obtainedfrom prime agricultural land,causing land degradation as wellas economic loss due to diversionof agricultural land. Though clay iseasily and abundantly available innature, its resources has athreshold limit and utilization of clayhas reached such a point inconstruction. Excess use of goodclay caused erosion of fertile soiland soil degradation and disturbedthe ecology.

The burnt clay brick industry inIndia produces over 60 billion claybricks annually resulting in strongimpact on soil erosion andunprocessed emissions. Forproduction of these bricks about

160 million tones of top soil, makingbarren 7500 acres of fertile land.(1) Because of all these ill effects,this is proper time to search analternative of the burnt clay bricks.

Use of Cement, Fly Ashand Phosphogypsum AsAn alternative for burntClay BricksThis is new technology which workswith the strength of fly ash, limeand gypsum chemistry. The slowchemistry of fly ash and lime ismaneuvered by tapping ettringitephase to its threshold limits throughsufficient limit of gypsum. Therefore,it does not require heavy duty pressor autoclave, which is otherwiserequired in case of only fly ash andlime. The process completelyeliminates the thermal treatment(except open air drying) and doesnot require combustion of any fossilfuel. The ingredients of the unitssuch as bricks and blocks, fly ash,

lime (from OPC) and gypsum arewell-known minerals that are widelyused in the industries. All theseminerals are available in the formof wastages and by-products fromindustrial activities. In certain areaswhere by product lime is notavailable in adequate quantity,Ordinary Portland Cement (OPC) canbe used as the source of limeproducing the good quality of bricksand blocks. This technology isproved to be environmentally safeand sound.

MaterialsFly ash used for the present studyis obtained from the Thermal PowerPlant, Eklehara, Nashik. As goodquality of lime is not available inthe vicinity OPC is used as asource of lime and Phosphogy-psum (CaSO4 2H2O) is obtainedfrom Savil Agrovates, a Kopargaonbased company producingagricultural product where

Use of CementFly Ash and Gypsum as an

In Civil Engineering traditionally, we are using different materials in theform of building units. Some of the building units which we are using forconstruction are bricks and concrete blocks. Especially for bricks wehave to use good plastic clay as primary raw material. This clay is oftenobtained from prime agricultural land, causing degradation as well aseconomic loss due to diversion of agricultural land. Manufacturing ofbricks produces harmful gases which results in significant air pollution.This feasibility study is an attempt to use cement, flyash and waste gypsumfor the manufacturing of building units so as to replace the traditionalbuilding material at least partially.

phosphogypsum is available as awaste.

Mix ProportionsAs our main intention is to searchan alternative material for theconventional burnt clay bricks byusing the waste materials and toproduce a low cost buildingmaterial, emphasis is given to usethe waste products to the maximumextent and hence following mixproportions are used for the presentstudy. The mix proportions are givenin the Table No.1 are in terms ofdry weights of the ingredients.Shrinkage cracking is a majorweakness in gypsum based blocks.Shrinkage cracking can beminimized by keeping the watercontent of the binder as low aspossible.

the water content for the normalconsistency was determined. Thewater content used in the mix forstrength tests was 90% of thatrequired to produce the standardnormal consistency.

Preparation of MortarBlocksStandard cement mortar cubemoulds of size 70.7mm x 70.7mmx 70.7mm were used for preparationof blocks. The mixed binder wasplaced in the cube mould and wascompacted properly by rod. Excesspaste was hand finished. Themould was filled in three layersand each layer was compactedproperly.

Method of CuringThe blocks were taken out from themoulds after 24 hours. After removalfrom the moulds the blocks werekept for air drying for 2 days. Aftersufficient strength was gained,these blocks were transferred towater filled curing tanks.

Experimental WorkTo check the feasibility of Cement,F.A. and P.G. binder as an alternativematerial for traditional burnt claybricks following tests are performedon the binder.

1) Compression Strength Test2) Water Absorption TestAbove tests were performed as

per Indian Standards (18), (19)

MethodologyMixing of Raw MaterialsThe weighed quantity ofPhosphogypsum, Cement and flyash were thoroughly mixed in drystate in a pan with the help of atrowel. The mixture in dry state ismixed till it attains a uniform color.When the mixture attains uniformcolor weighed quantity of water isadded in the mixture of fly ash,cement and phosphogypsum. Afteraddition of the required quantity ofwater the mixture is thoroughlymixed with the help of trowel in apan. After mixing the mix initiallywith the trowel the mixture is againmixed thoroughly by kneading untilthe mass attained a uniformconsistency.

To calculate the quantity ofwater to be added Standard normalconsistency test was performed and

Alternative Material

Density TestAfter 28 days of casting, the cubeswas dried to a constant mass inan oven at 1050C they were cooledto room temperature and theirdensity was obtained

Table No. 2. The results ofcompressive strength are presentedin Graph No.1 to 4, Graph No. 1 to4 show the compressive strengthof cubes having different proportionsof fly ash and phosphogypsum. The

results indicate that thecement, F.A. and P.G. Mix havepotential to use as buildingmaterial as an alternative fortraditional burnt clay bricks.This is due to the fact that flyash acts as a source ofreactive Silica and Alumina, togive Calcium Sulphoaluminateand Silica hydrates, which areresponsible for strength. It isobserved that the strength ofthese blocks increases withage. The maximumcompressive strength of theseblocks can be obtained with aspecific proportion of theingredients. It can be observedfrom the test results that thestrength of the cubesdecreases as the percentageof fly ash and phosphogypsumincreases. From the resultsof water absorption, For mixM-1 (with 50% fly ash andphosphogypsum) and for M-2(with 60% fly ash andphosphogypsum) the

percentage water absorption isalmost same. For 70% and 80% flyash and phosphogypsum waterabsorption decreases.

For economy, the fly ash andphosphogypsum content should bekept as high as possible. Theminimum average crushing strengthprescribed in Indian code for burntclay bricks is 3.5 MPa (20). As thecompressive strength at 7 days forM-4 is 5.63 MPa and that at 14days is 9.96 MPa, it can be saidthat the material is having adequate

strength to produce bricksfrom it.

From Table No.2 it canbe observed that the waterabsorption of cubes in thepresent investigation wasobtained to be in between24.91% to 30.37%. As per

Graph No.3: Variation of CompressiveStrength with age for M-3 Mix

Water Absorption TestAfter casting the cubes of each mixproportion, the cubes wereimmersed in water and after 28days of curing the cubes were takenout of the curing tank and theirsaturated mass was recorded afterthe cubes were kept in oven at1050C and dried to a constantmass and dry mass of the cubeswas recorded. After that finding thedifference between the saturatedand dry mass percentage waterabsorption was calculated.

Summary of TestResultsTable No. 2 shows summary of alltests results.

Test Results andDiscussionsA large number of blocks weremade with different proportions offly ash, cement and phosphogyp-sum. The experimental results arepresented in graph No.1 to 4 and

the code (20) the water absorptionof ordinary burnt clay bricks shouldnot be more than 20% by weight.Clearly the water absorption forsome proportions is morecompared to that of traditional burntclay bricks. Nevertheless suchbricks can be used for curtain walland partition walls where theconsequences of the high waterabsorption capacity will be lesssevere. However, this aspectcertainly needs further investigation.

The weights of variousdesignated cubes are found to beless than that of ordinary burnt claybricks. The reduced weight ofCement, F.A. and P.G. will provide aworking comfort and ease ofhandling, in addition to reduction indead weight of structures.

ConclusionBased on the experimentalinvestigation reported in this study,following conclusions are drawn.

Unique possibility exists for thebulk uti l ization of fly ash inproducing bricks from Cement, F.A.and P.G. in the proximity of thermalpower plants, phosphoric acid andfertilizer industries.

The test cubes are havingsufficient strength and havepotential as a replacement forconventional burnt clay bricks.

Cementitious binder with fly ashand phosphogypsum content equalto 80% gives better compressivestrength and 20.25% waterabsorption and thus suitable for usein construction industry.

Being lighter in weight, Cement,F.A. and P.G. mix will reduce thedead weight and material handlingcost in multi storied constructions.

The utilization of wastes inmaking cementitious binder willhelp in solving the disposal andhealth hazard problems. It is furtherneeded to develop awarenessamong users, professionals andfinancial supporters for using thesewaste materials for techno-economic reasons in addition tobalance economy and achieve

energy conservation. The use ofthese wastes for building industrieswill definitely reduce theenvironmental pollution which willbe there because of use of burntclay bricks. Such products can beused for low cost constructionpractices.

Investigation

IntroductionIncrease in service loading,environmental degradation, damageof structure due to poor quality ofmaterial and inferior design,upgrading of old structures as pernew code and need of seismicretrofit leads to the need of repairand rehabilitation. Rehabilitation ofdeteriorated civil engineeringinfrastructure such as beams,girders, bridge decks, parkingstructures, marine structures, roadsetc has been the major issue inthe last decades. The need toupgrade the deteriorated civilengineering infrastructure greatlyenhances with the ever increasingdemands. Therefore rehabilitatingexisting civil engineeringinfrastructure has been identified asan important issue to be addressed.The strengthening of concretestructures to resist higher designloads, correct deterioration-relateddamage, or increased ductility hasbeen traditionally accomplished

using conventional materials andconstruction techniques. Externallybonded steel plates, FRP and ferro-cement laminates are some of thetraditional techniques available. Inthe context of strengtheningproblem, advanced compositeshave the potential to prove anotherpromising solution.

Introduction toFerrocementFerrocement is a form of reinforcedcement mortar (micro concrete) thatdiffers from conventional reinforcedor pre-stressed concrete primarilyby the manner in which thefollowing elements are dispersedand arranged. It consists of closelyplaced, evenly distributed multiplelayers of mesh or fine rodscompletely embedded in cementmortar. Widespread use offerrocement in construction industryhas occurred during the last 40years. The main worldwideapplication of ferrocement

construction to date has been forsilos, tanks, roofs, irrigationchannels, manholes & covers, andmostly boats. The construction offerrocement can be divided in tofour phases:♦ Fabricating the steel rods to form

a skeletal (cage) framing system;♦ Tying or fastening rods and mesh

to the skeletal framing;♦ Plastering and♦ Curing.

Experimental Investigationon Flexural Behaviour of ReinforcedConcrete Beams Strengthened byFerrocement Laminates

B.Sivagurunathan, SelectionGrade Lecturer in CivilEngineering, Thiagarajar Collegeof Engineering, Madurai.Dr.B.Vidivelli, Professor in Civiland Structural Engineering,Annamalai University,Annamalai Nagar.

This paper investigates the flexural behaviour of reinforced concrete beamsstrengthened by ferrocement laminates. Totally five beams of length 3200mm,width 150mm and depth 250mm were cast and tested. A flat ferrocementlaminate 125mm wide, 25mm thick and 3000mm long was cast using cementmortar as binder and weld and woven mesh as reinforcement. The experimentalstudy shows that the ferrocement laminate increases the flexural bahaviour ofthe distressed reinforced concrete beams. The aim of this project is to bondferrocement laminates to reinforced concrete beams and strengthen it againstflexure.

load of the original beams usingferrocement laminate and to controlthe cracking behavior of the beamsas well the effect of the damage oforiginal beams prior to repair areexamined.

It is concluded that thestrengthened beams haveperformed better in crackingbehavior, reduction in mid-spandeflection and increased ultimateload. Further, the pre-crackedbeams prior to repair did not affectthe ultimate loads of thestrengthened beams tested.

Mohd Zamin Zumaat andAshraful Alam (2006),

In this study, methods ofstrengthening of reinforced concretebeams using ferrocementlaminates with skeletal bar attachedon to the soffit of the beams arereviewed. The addition offerrocement laminates with skeletalbar to the soffit (tension face) ofthe beams substantially delayedthe formations of first crack,restrained the crack widths andincreased the flexural stiffness andload capacities of the strengthenedbeams. The effects of curtailing theferrocement laminate short of thesupports were studied. In thestrengthening carried out in thepresent work, the ferrocementlaminates were extended over thesupports. This however would bedifficult to achieve in practice.

Vidivelli.B, et al (2001),In this study, the damage due

to overloading is considered. A totalof three beams were cast andtested. One beam (control beam)was tested to ascertain the loaddeflection behaviour and ultimateload. The remaining two beamswere damaged by overloading. Afterunloading the damaged beamspecimens were repaired withferrocement laminates with singlelayer at tension face using epoxy.Static test was conducted on all thebeams to determine the loaddeflection behaviour and ultimateload. A comparison was made oncrack width, deflection and ultimate

strength at different loadstages between control,damaged and repairedbeams.

ExperimentalProgrammeMaterial UsedFor the beam specimen, theconcrete with designcompressive strength of M20was used. The concrete mixproportions are given in Table1. 43grade Portland Pozzalana Cement(PPC) confirming to IS: 1489 –1991, having a specific gravity of2.92 was used. Locally availableriver sand having a finenessmodulus of 2.61, specific gravity of2.65 and coarse aggregates of20mm maximum size, having afineness modulus of 6.97 andspecific gravity of 2.9, were used.High yield strength deformed barsof Fe 415 were used asreinforcement in the concrete beam

For casting of the ferrocementlaminates Portland cement mortarmatrix, woven and welded meshesof size 24 gauge are tied togetherto act as reinforcement.Ferrocement may require chemicaladditives to reduce the reactionbetween the matrix and thereinforcement.

Details of TestSpecimenFive beams were cast for flexuraltest out of which one beam wascontrol beam the second and thirdwere tested for service load andrehabilitated and the fourth and fifthbeams are retrofitted.

were removed from mould after 24hours of casting and then curedusing jute bags. All specimens weremoist cured for 28 days.

Bonding ofFerrocementlaminate to beamBefore bonding the fabricatedferrocement laminates on the soffit(tension side) of the concrete beam,surface was made rough usingsand blasting and cleaned with anair blower to remove all dirt and

debris. Once the surface wasprepared to the required standard,the epoxy resin was mixed inaccordance with manufacturer’sinstructions. Mixing was carried outin a metal container with base tohardener ratio of 1:2 and wascontinued until the mixture obtaineduniform colour. Then it was appliedboth on laminate and beam surfaceand bonded properly without anyair gap.

Experimental set-upTwo-point loading system was

adopted for the tests.At the end of each loadincrement, deflectionand ultimate load werecarefully observed andrecorded. The ultimateload for the controlbeam was found out.Then the other twobeams (S) were testedfor service load andrehabilitated withferrocement laminates.The other two beams(R) were retrofitted withferrocement laminates.

The rehabilitated and retrofittedbeams were again tested by twopoint loads and at the end of eachload increment; the deflection wascarefully observed and recorded.The recorded values are graphicallyrepresented and are shown in Fig.6.

Results andDiscussionsFrom the test results summarizedin Fig.6, it can be concluded thatthe rehabilitated beam withferrocement laminates 12% lesserload than the controlled beam. Theretrofitted beam carries 18% moreload than that of control and 24%of rehabilitated beam. Fig.6 showsthe ultimate load carrying capacityof the beams with differentconfiguration.

Although currently there are noindustry standards specifyingconcrete tolerances specific

to polished concrete, manufacturersas well as installers are coming upwith their own set of standards toobtain a quality polish job. On newconcrete installations that willultimately receive polishing, certainperformance criteria need to be metso the polishing company canperform a uniform quality job.

On new concrete installations,the concrete mix design is critical.Using a cement-rich concrete(typically 3,500 psi) provides adense surface free of voids for thepolishing process. We can alsouse many times water-reducingadmixtures to keep a low watercement ratio without jeopardizing theworkability during the concreteplacement. Wet curing of the newslab is an excellent way of curingbut many times it is not practical. Ifthis is the case, dissipating liquidapplied curing compounds are a

Polished Concrete Floorsgood way to cure the slab. Anyremaining curing compound thatdoes not dissipate over time isusually easily removed during thecoarse-grinding phase of thepolishing process.

Of equal importance to theappropriate mix design is how theconcrete is placed and finished. Theflatness and levelness of theconcrete substrate is crucial notonly for a uniform polish, but alsohow the project is bid. Floors thathave excessive highs and lows willrequire a tremendous amount moregrinding, increasing your labor costsas well as the costs of yourdiamond tooling.

According to industry standards,finished concrete shall have aminimum Floor Flatness rating ofat least 40. The industry standardfor terrazzo is no more variancethan 1/4 in. in a 10-ft. span, whichcan also be applied to polishedconcrete. If the slab is beingmachine troweled with walk-behindmachines, it is imperative to notleave indentations or boot marksbehind since they are not easilyremoved during the polishingphase.

The main methods of coloringpolished concrete consist ofintegrally coloring the concrete mixor staining or dyeing the surfaceafter the fact. By far the easiest andmost controllable method is tointegrally color your concrete. Mostintegral color is either in the liquidor powder form and added at theready-mix batch plant and thenmixed for a specified time. Colorloads for integral color should neverbe smaller than 3 cu. yds. for colorconsistency. Colored aggregate orcrushed glass can be added to theconcrete mix or hand seeded intothe top layer of the mix. Thepolishing process will reveal theunderlying aggregate.

Adding colors to polishedconcrete, either integrally or withstains and dyes, can create adistinctive look for your floors.

Acid staining or dyeing is agreat method of achieving color onpolished floors. Different applicatorshave different methods and timeframes of applying the stains anddyes. We have had excellent resultswith applying dyes around the 400-grit phase. Let’s review the process:♦ Coarse grind with 40-grit metal

bond (if necessary)♦ Grind with 80-grit metal bond♦ Apply densifier♦ Grind with 150 metal bond♦ Remove scratch pattern from 150

grit with 100/200 resin bond♦ Remove scratch pattern from 100/

200 grit with 400 resin bond♦ Apply color stains or dyes♦ Polish with 800-grit resin bond♦ Polish with 1,500-grit resin bond♦ Polish with 3,000-grit resin bond

There are certain situations thatthe consumer may not choose a3,000-grit polish. Most HomeDepots or Lowe’s, for example,typically are polished to 800 grit.There are many levels of polished

floors that stop short of truly being“polished concrete,” but have theirown unique and distinctive look.

For the professional polisher, itis often debatable if some type oftopcoat is needed with someclaiming that it defeats the purposeof polishing relative to the ongoingmaintenance. Especially whenusing dyes, we feel that it isnecessary to apply two thin coatsof reactive penetrating sealer to helplock the color in. If applied properly- over a clean surface in multiplethin coats (1,500 to 2,000 sq. ft.per coat per gallon) - this provides

an extremely hard surface andhelps preserve the finished floor.Because most of the materialpenetrates the surface and isapplied very thin, scuffing orscratching is usually not a problem.

Dealing with edges up againstwalls is always an issue. If thepolished surface is to terminatedirectly against the wall, there arewalk-behind machines to addressthis. Most of the time, tooling byhand with grinders and diamondpads is necessary. Another way toaddress edges is to use differentmediums and create a bordermaking the edge an architecturalfeature. We have had great resultssaw-cutting a border in and thenusing cement based skims orcolored epoxy.

If you are considering to pursuethe polished concrete market, makesure you do your homework. Thepurchase of equipment can be a

large investment. Talk withmanufacturers of polishingequipment and ask why theirequipment and services are betterthan others. Make sure you have amarket to support the heftyinvestment. Polishing machines canalso be used for other applications,such as adhesive and coatingsremoval or to prepare surfaces fordecorative overlays, to name a few.

The demand for cranes is going upin almost all sectors due toincreasing infrastructuredevelopment work in the country,more so in port and power sectors.Of late, it is picking up in theconstruction sector (such as cementand real estate), said Mr. RamanJoshi, Managing Director, ManitowocCranes India. Manitowoc, he addedis well-equipped to fulfill and serve

also being used in the importantGovernment and private sectorprojects.

Manitowoc has also invested alot to further upgrade ManitowocCrane CARE Service facilities. It isaltogether different service conceptfrom those available in the market.It is a satisfying concept for ourclients assuring them of maximuminvestment return on their crane

to provide innovative mobilesolutions, said Mr. Joshi.

Maximum jib length on the MC125 is 60 m and in standard form,the crane has five possible jiblengths, including the 60 mmaximum. The others are 30 m, 40m, 50 m and 55 m. It also has amaximum free-standing height of44 m but can reach much higherby telescoping and tying off tostructures. The crane’s maximumcapacity is 6 t while at the 60 m jibend, it can lift 1.15 t.

The crane’s lifting technologyincludes a double trolley allowing itto lift 3 t when working with a singletrolley or 6 t when working withboth. Two versions of Potain’sestablished 24 kW 33PC15 hoistare available with the crane.

When working with a 480 Vpower supply, the 33PC15(GH),which has 400 m of rope availablefor high-rise building work, can offerlift speeds of up to 96 m/min whencarrying 1.5 t on the hook. Theregular 33PC15, which has 260 mof wire rope available, can reach90 m/min when working with thesame load.

The GT25-5A is a 25 t capacitycrane mounted on a three-axlecarrier. It has a five-section 40.2 mtelescopic boom that offers a 49 mmaximum lift ing height whenworking with the jib. Power for thecrane comes from a SinotruckWD615.92 engine, compliant toEuro III standards, offering a poweroutput of 196 kW at 2,200 rpm.

The engine drives a hydraulicsystem that includes a four-circuitpump that automatically combinespump flows to speed up operations,as needed. In addition, a variableflow hydraulic motor provides theflexibility for optimal line speed. Thecrane is suitable for tower craneserection and to set up industrialprojects.

Infra DevelopmentsInfra AgendaThe need for quick delivery ofresults has been an ongoingexercise for the Government toinfuse new initiatives to get betterperformance from infrastructuresectors. But every new changeaffected makes the situationunchanged. To this effect, there havealready been reviews of performanceof infrastructure industries anddepartments connected with thembut these have been of no availand initiatives have proved to be anexercise in futility. There is anundercurrent of expression ofdisenchantment over uninspiringperformance of infrastructuredepartments. The recent Ministerialshake up in key economic andinfrastructure ministries in naturalgas, civil aviation, roads andhighways, heavy industries, urbandevelopment has been another softhandling attempt. The move to re-jig various ministerial portfolioscame at a time when the country isfacing twin challenge of containinginflation and improving industrialperformance. At the best, it onlydelivers a diffused message that

departments need to pull up theirsocks and a further exercise wouldbe undertaken after the budgetsession. These changes aimed ataccelerating the pace of work andimprove performance leaveeveryone guessing whether they willachieve what is desired particularlybringing back the sectors on theroad to recovery as promised bytheir predecessors. One can onlyhope that in the new dispensation,the infrastructure sectorsgrowth would be taken to newheights and moves ahead on avisible infrastructure agenda swiftlyunder new management structureand nonperforming system is underregular scrutiny beyond weaktinkering.

Raw Materials,Finance and LaborCrunchA number of ongoing projects arefacing a fund crunch to go aheadwith the work. Project developersare finding it difficult to raise moneyto procure raw materials. Added toit is the deferment of projects fromthe governmental agencies,reluctance of investors to put money,shortage of trained workforce.Companies like L&T, HCC andIVRCL are particularly affected dueto these concerns and are of theview that core sector could witnessa slowdown spell and havepostponed their projects in hand.Orders worth more than `50,000crore have been pushed back byvarious governmental as well asprivate agencies due to some ofthese factors, says L&T PresidentConstruction, Rangaswami. Echoingthe same HCC, Chairman AjitGulabchand said, investors are notpumping in money and orders areslowing down. He in particular cited

the example of Lavasa projectwhich is facing problems due toenvironmental issues and hascaused a concern in the minds offinancers. Finances are tight asbanks are unwilling to lend moneyto projects which do not have aclearance in place. Then there isalso the impact of rise in steel andother building materials prices.There is also an acute shortage ofconstruction workers with mostworkers opting for governmentpromoted employment guaranteeschemes. Due to this, wages havealso gone up and the net result isthat raw materials and laborconstraints are slowing down thepace of works in the constructionsector.

Gold Bonds for InfraSectorBanks have mooted a proposal andhave sought Government approvalto raise funds via infra and goldbonds with long-term tenure. Bankshave stated that they are dominantlenders in the infrastructure sector,so they should be allowed to raisefunds through such tax free bonds.Currently, only infrastructurefinancing companies like IDFC, L&T,REC, PFC, Srei InfrastructureFinance as well as IFCI and LIC canissue such bonds. The bankershave therefore sought level playingfield for them in this area. Theyhave also sought TDS exemptionon other sources of incomeincluding brokerage income.

Road & Highway Projects

Private Bank Keenon Funding RoadProjectsFinding that road projects in thecountry are giving good return oninvestment, private banks are verykeen to fund road projects. Three–four years back, there were onlynationalized banks which weregiving such loans as private bankswould not touch these long-termgestation projects, said a companyengaged in road constructionprojects. As a result of which, todayroad companies have a widerchoice and the basket of lenders tothis sector has increased. Earlier,there were five – ten who used toregularly lend for road projects.

Over the years, lenders havebecome more confident about theroad sector, as it has demonstratedquite a few success stories, saidCEO, IL&FS. Construction costs inthe sector have become morestable as compared to three-fouryears back. Now costs are undersome control. Policy reforms andmore importantly, better projectmanagement, better trafficestimation, cost, time and contractmanagement has improved theperception about the road sector,said Bank of India. This hasadvanced the break-even for manyroad projects. It is more so for

national highway projects than stateprojects, the Bank added. RBIextension of loans to infrastructureas secured loans, where bank canensure that infrastructure assetscan be used as a security for theloan, has given the banks moreheadroom to lend to these projectsbenefiting the road constructioncompanies. According to expertsroad construction companies arebecoming more efficient, with manyprojects being commissionedwithout much delays, thus makingbanks more confident about theirexecution capabilities.

Steel Construction

Steel has become a universalbuilding product due to itsstrength, versatility, durability

and economic value. The use ofcoated steel for structures, roofing& wall cladding is growing rapidlybecause it offers a variety of benefitslike aesthetic appeal and longservice life. As a result of themetallic coating (zinc / aluminum /zinc–aluminum alloy) on the basesteel, today’s metal roof & wallpanels resist corrosion and providea service life of 20 years or more oftrouble-free performance. Usingcoated steel for framing is anexcellent method to build a buildingthat will last for generations. Thesebuildings look like any other andyou would have to be told one had

a steel frame. “Steel” buildings canbe constructed in virtually anyarchitectural style and size withmany pleasing features andfinishes. The result of this is outthere for everyone to see withnumerous examples of Industrialand commercial applications usingcoated steel.

BuildingConstruction-Designflexibility with steel..!!!When we talk of design flexibility ofa building material pertaining toconstruction, following becomesimportant for its adaptation in thebuilding design.

Can this material be used forresidential/ industrial/commercialpurposes?Is this material suitable for all i.e.low, mid and high-rise structures?How easy is it to use it? Can thelocal unskilled labour be used?Can the small structure be self builtby user?Aesthetically how would it appeal?Can one make fancy designs withit?Cost wise how does it compare?Are there choices/variants fordifferent users with differentfinancial capacities?How much time does it require tobuild a structure with such amaterial?

Design Flexibity inConstruction with Steel

Rajesh Maheshwari, Head Technical Marketing (Coated Steel) at Tata BlueScope Steel Limited

Can the design with this materialallow for easy expansion/relocation/reuse?Can more free space possiblewithin same buildup area?What is its compatibility with otherconstruction materials in samebuilding?And very important how easy/difficultis its maintenance?

And when one thinks of steelfor building construction, its usageswould be presumed primarily forthe strength steel posses. It is alittle difficult to consider that steelprovides the design flexibility also.But then in the modern era, theinnovative and very impressivebuildings with steel have been inexistence around the world. It wouldhave been impossible had steelnot provided flexibility in its usage.Let us discuss how does steel asbuilding material offers functionalas well as aesthetic qualities andprovides design flexibility.

According to International ironand steel institute (IISI), 1/3rd of thetotal steel produced is consumedin construction activities and it isexpected to go higher and higher. Itis because of the flexibility itprovides to designer and user. Thevery first flexibility steel provides isfor primary members in the form ofrolled sections v/s fabricated onei.e. conventional building v/s Pre-engineered Building (PEB)/MetalBuilding Systems. But when weconsider coated steel sheeting, weare talking of the flexibility it providesin the form of variety of claddingprofiles in multiple options in colors,paint systems, metal coatings,strengths (grades), lengths, widths,thicknesses for nearly everyconceivable building design. Thuscoated steel sheets offer excellentdesign flexibility, and contributes toenergy savings through its highreflectivity, recyclability & reusability.Reduction in consumption is alsoachieved through usage of thinnerand high strength material therebycontributing towards environment

protection. Solutions are there forurban/suburban, individual, massmarket in prefabricated units,customized units with higharchitectural design, commercial/residential, Do-it-yourself kits (withgenerally pre-punched serviceholes for electrical and plumbing).Long life and low maintenance arethe driving forces behind mostcommercial building exteriortreatments. For these benefits, ofthe many options available, coatedsteel has emerged as the roof orwall material of choice in manyapplications.

Design AestheticsMany building owners seeking long-term roofing solutions are insistingon metal roofs that offer both curbappeal and exceptionalperformance. Bold design thatinspires and creates a lastingimpression is made possible withmetal. Of it, coated steel is veryflexible because it can be usedwith various other materials tocreate a contemporary and stunninglook.” Steel can accommodate avariety of external finishes ofbrickwork, insulated renders, timber,tiles, and curtain walling. Steel canbe easily cut to custom lengthsand widths, so builders can designto varied choices. Architects and

designers can employ longer spanswithout requiring as many structuralor load-bearing walls or partitions.The result: more attractive designoptions, including longer floorspans, higher ceilings and largeropen spaces. Roofing and wallingsheets come in a range of profileshapes. Downpipes are availablein square, round or rectangularprofiles, and gutters in a wide rangeof styles, shapes and sizes. Thisallows flexibility in product suitablefor a number of applications anddesigns mean even more flexibilityin design with great aesthetics.Designing with metal offersperhaps the widest array of choiceswithin the construction industry.

Different PaintSystemsPaint system provides durability andlife. Paint system means paint-primer-conversion coatings. Thepaint is the top coat and back coat.Paints types of Polyester (RMP,Super Durable)/SMP/PVDF/Metallicetc are available. Paintmanufacturers have their ownvariants to these classes of paints.Each has its suitabil ity witheconomic value to meet differentrequirements. Based on which, bestsuiting one is chosen for a designand environment.

Choice of ColorsDepending on your supplier, youcan choose from standard set ofcolours with option of your own one.You can also choose the naturallook of zinc or copper, or coatingsthat make metal look natural.Coated steel sheets are nowavailable in many colours to usesingly and in combinations to makedesigning flexible. Colour isimportant not just for looks; it hasinfluence on inside comfort andenvironment. Thermal efficiency ofbuilding depends also on the colourof roof and wall.

Metallic CoatingDepending on the life expected fromthe building material, theenvironment and activities inside,metallic coating option is exercisedfor corrosion protection. 55% Al-Zncoating compared to Zinc coatingprovides much better corrosionprotection in near neutral condition(typical of most environments).

Possibility of designswith curvesFlexibility of design allows for bothtraditional straight roof sheeting aswell as innovative curved roofingdesigns. Coated steel with differentbase steel strength provides virtuallylimitless design possibilities. Dueto its flexibility, it is capable ofaccommodating the double radiusof the curved roof, with greataccuracy of the curves. From flowingcurves to precision flatness, metalis easy and economical to install.This freedom of design providesthe architect and owner theopportunity to build within a widerange of styles and create an imagethat will endure.

Variety of RoofDesigners and users have a choiceof roof & wall with or without visiblefasteners. Advances in technologysuch as the standing seam roofwith no visible fasteners and leak

proof warranty give designers evenmore flexibility for innovating withbuilding structure and style.

Options of differentslope for roofsThere is choice of low slope andsteep slope for roofs. In bothcategories of roofs, steel with highlydurable metallic & paint coatingscould be used and the benefits ofhigh performance realized. It’s themetal roofs which added the designelement of steep slope to a buildingthat separates them fromconventional flat ones. Low sloperoof are more economical, steepslope metal roofs enhances theappearance of virtually any building.Steep slope metal roofs acceleratethe rate of water run-off, reduce thelikelihood of a build-up of debris,mold and mildew, less likely toexperience staining from acid rainor UV degradation. The durabilityand reliabil ity of steep slopesystems is quite long.

Best utilization ofSpaceLarger interior spaces (highclearances and spans) withoutinterior columns add flexibility todesign & increase utility. At times

this large span is a mustrequirement e.g. aircraft hangar.However, it could only be achievedwith self-supporting steel framingsystem with no need for interiorwalls to help bear the weight of thebuilding. With this self supportingsteel frame interior walls can easilybe eliminated, altered or relocatedand large open floor plan createdincluding raised ceilings. Thisexcellent spanning capabilitiesoffered by steel framing providesmore flexibility in designing internalspaces that maximise opportunitiesfor cross ventilation, helping to meetenergy efficiency requirements.

For some things there is simplyno equivalent, like roofing andwalling made from lightweight,versatile and durable coated steel.Stronger and lighter as a combinedmaterial than all other alternatives,steel is giving builders and buildingdesigners greater scope to createwider rooms and higher ceilings,as well as support for innovative,non-conventional roofs that areincreasingly being used to giveproperties a style of their own. Highstrength (minimum 550 MPa yieldstrength) coated steel are fastbecoming the materials of choicebecause of its high strength-to-weight ratio, and the design flexibilitythey offers. It gives great spanning

capabilities, especially with unusualshapes, and can cover a buildingwith minimal structural support,allowing for more column free floorarea. To obtain a desired designyou can reduce the width of thejoist but compensate with heaviergauge steel and not change thespacing of member.

Time frame FlexibilitySince steel buildings are quick toerect, the constraint of time isminimal. Frame, wall and roof madefrom steel can be erected quicklyand easily, saving time and stress.Off-site pre-fabrication ensuresdimensional accuracy and on-siteerection and fixing to be fast andsimple. Service holes can also bepre-punched for plumbing andelectrical. Steel building has lessweather-dependency (lower “down-time / construction time”) can beinstalled in wet conditions unliketraditional materials. Swift erectionof a building in steel can cut weeksoff the average construction time.This way steel building providesflexibility to designers & buildersas well.

Design FlexibilityCost?The variety in steel contributes tothe flexibility of design for costingas well. These varied options havedifferent cost associated with them.Steel construction offers thepotential to build substantially morecovered space with the same cashflow. Steel building can be built inmuch less time without increasingsite resources, thus freeing capitaland finite resources for other

projects – “The efficiency of use ofworking capital”. Offsiteprefabrication increases the speed,efficiency, quality and safety ofconstruction. It is also easy tointegrate into existing structuralsystems. The predictability of costand program also improves. Timerelated savings when specifying astructural steelwork frame comparedwith reinforced concrete can be 2 –3% of overall building costs.

Components of steel roofingand walling are supplied to precisespecifications so there is little orno wastage on site and the cost ofdebris removal. Most onsite wastecan be sold afterwards as scrapthat is recycled into other steel-based products. It is cost wise &environmentally good. Coated steelsheet assemblies are economicaland durable under toughenvironmental conditions. Costarising out of natural calamity isminimal.

Flexibility to ReuseSteel building materials have greatopportunity for re-use. At times,designers use this flexibility for newprojects with new look using oldmaterial. This not only saves cost,it also reduces impact on naturalresources.

Flexibility to RelocateThe other great comfort of theflexibility steel building user has isthat it can be relocated. This hashelped many users to release costlyland resource and rebuild thesimilar installation with much lowerrelocation cost.

Flexibility to ExpandThe benefits of steel buildingsystem are seen today, tomorrowand in the future. When you erect ametal building today, you have thebenefit of cost efficiency, designflexibility, and the predictability ofon-time construction deadlines.Tomorrow, your benefits continuewith minimal maintenancerequirements. In the future, as yourbusiness flourishes or your needschange, the building iscomparatively easy to expand andupdate.

Flexibility to useLocal LabourOn-site construction of steelbuilding is easy, highly efficient andsafe, which an untrained personnel,can quickly learn.
