The Secretary’s report began with mem-bership statistics. Membership of theSociety was reported as 1,701 individu-als of whom all, but 216, are ChapterMembers, 2 Benefactors, and 86 Corpo-rate Members. Another item of the re-port addressed electronic publishing ofIGS documents. Much discussion led tothe conclusion that IGS News would beposted on the IGS website for Member-ship downloading. IGS News will alsocontinue to be published in hard copy;however, it is hoped that the Member-ship will shift to electronic distributionthereby saving the IGS substantial costsfor printing and mailing.

Next, the very successful StudentAward Program was discussed, resultingin several changesbeing madeto thePro-gram. Council Member M. Lopes wasappointed Student Mentor, a position in-tended to be the student award winnersadvocate at future conferences and ex-hibitions (seven student winners wererecognised at EuroGeo2 in Bologna, Ita-ly). The structure of the Program wasamended for future meetings. Specifi-cally, students are to be provided: a copyof the conference proceedings, free at-tendance to sessions, and a studentmeet-ing or session during the conference.

The Secretary’s report continuedwith the nomination (and approval byCouncil) of C. Lawson and T. Akagi forthe IGS Service Award. Mr. Lawson and

Prof. Akagi join Dr. D. Elton as recipi-ents of this recognition of special efforton behalf of the IGS.

The Treasurer’s report will be pub-lished in detail in a separate article. TheSociety is financially healthy and is ac-tively putting its financial resources towork tobringbenefitsto theMembership.

The Chapter Committee reports thatseveral new chapters are possible. Bel-gium has submitted bylaws forapproval;Turkey, Slovakia, and Portugal arework-ing to form their Chaptersby 1December2000 in order to be included in the 2001IGS Directory. Other potential chaptersare under development in Australia, Ma-laysia, Scandinavia, and Thailand.

TheEducationCommitteereportsthatthe Lecture Program is nearing comple-tion. At present, efforts are underway toinsure all lectures (20) are presented in aconsistent format. The geosyntheticsteaching lectureswillbeproducedontwoCD-Roms foruse by the Membershipandeducators.

Geosynthetics in Forest Engineering —Design Principles and Best Practices

Instructor:

G Jonathan Fannin, Ph.D., P.Eng.,University of British Columbia, Van-couver, British Columbia, USA

Geosynthetic stabilisation of soils in-volves four basic functions: reinforce-ment, separation, filtration, anddrainage. The extent to whichsome orallof these functions are mobilised is gov-erned by the construction applicationand site conditions. This course de-scribes the selection, specification, andinstallationofgeosyntheticsinengineer-ing projects. Specifically, it addressesthe use of geotextiles and geogrids.

Objectives of the course are twofold.The first is to assist users in exercisingtheir professional judgement andexperi-ence in developing site-specific recom-mendations for construction. (Tenconstruction case reports are used tohighlight important points.) The secondobjective is to promote the use of bestpractices in construction. Examples aredrawn from the selected case reports andwill include unpaved roads, cut-slopeand fill-slope stabilisation, subsurfacedrainage, riprap revetments, and rein-forced soil bridge abutments. Guidanceis developed with reference to standardspecification documents, in particularAASHTO M288, together with relevantfoundation engineering manuals.

GeosyntheticsforInstallers/Contractors

Instructors:

G Sam Allen, Division Manager, TRI/Environmental, Austin, Texas, USA

G Joel Sprague, P.E., TRI/Environ-mental, Austin, Texas, USA

Many of the most economically advan-tageous applications for geosyntheticsare found in common private sectorconstruction projects. Commercial con-tractors and installers interested in thetechnical and economical advantagesassociated with the use of geosyntheticswill find this course to be a valuable op-

portunity to increase their practical geo-synthetics knowledge. “Geosyntheticsfor the Installer/Contractor” will includea basic introduction to geosynthetics,with special emphasis on applicationba-sics, technical and economical advan-tages, and installation guidelines.

The course curriculum will highlightdescriptions of geosynthetic applica-tions with rationale and installationguidelines, as well as address the use ofgeosynthetics in road structures, subsur-face drainage, erosion control, soilstructures, and liquid containment sys-tems. There will be extensive discus-sions of reinforcement geosyntheticsused in embankments over soft founda-tions, subgrade stabilisation, base rein-forcement, asphalt reinforcement,slopes, walls, and soil veneers.

Each student will be provided theGeosynthetic Materials Association’sGeosynthetics Handbook in addition tothe course notes. The Handbook coversmany of the short-course elements aswell as related manufacturer and speci-fication information.

Pavement Systems Design withGeosynthetics

Instructors:

G Barry R. Christopher, Ph.D., P.E.,Christopher Consultants, Roswell,Georgia, USA

G Ryan R. Berg, P.E., Ryan R. Bergand Associates, Inc., Woodbury,Minnesota, USA

G Steve Perkins, Ph.D., P.E., MontanaStateUniversity,Bozeman,Montana,USA

Pavement system construction and de-sign can be significantly improvedthrough the appropriate use of geosyn-thetics. Use of the appropriate geosyn-thetics for the specific application andproject conditions can be directly trans-lated into significant cost benefitsthrough improved/expedited construc-tion, extended life of the pavement sec-tion, and/or reduction in other pavementcomponent requirements.


The course is designed to meet theneeds of civil engineers and others whoare involved in the design, construction,and maintenance of permanent pave-ment systems. The instructors will dis-cuss some of the theoretical aspects ofroad design using geosynthetics. The fo-cus of the course will be on the practicalissues involved with problematic soils,drainage, overall pavement design im-provements, and maintenance issues.The training is broad based and shouldbenefit those having little, as well asthose who have extensive, previous de-sign and geosynthetics experience.

The instructors will demonstratehow to improve pavement system de-signs with geosynthetics. Each geosyn-thetic function will be discussed andrelated to design concepts and perfor-mance properties including recom-mended design practices. Improvedperformance will be demonstratedthrough life-cycle cost-benefit analysesand documented case histories. Selec-tion, specification, and constructionprocedures will be covered. An over-view of geosynthetics in maintenanceand rehabilitation applications such aspothole repair and asphalt overlays willalso be presented.

Interface Friction/Direct ShearTesting and Slope Issues

Instructor:

G Sam Allen, Division Manager, TRI/Environmental, Austin, Texas, USA

Understanding the specification of in-terface friction testing and how to inter-pret and use generated test results havebecome crucial elements of engineers’jobs. The stability of landfills and leachpads is becoming more important witheach newproject failure and the increas-ingly difficult terrain of some sites. En-gineers, working with slope stabilitydesign issues for the first time, togetherwith geomembrane and geosyntheticclay liner (GCL) manufacturers, havelong complained of the difficulty inachieving good, reliable interfacestrength parameters.

This course will focus on the design-er’s use of interface strength data includ-ing sources of interface strength, peak

versus residual strength, normal stressand failure envelopes, friction angle, ad-hesion, and slope stability calculations.Included will be detailed forensic analy-sis of an example slope failure. In addi-tion, the short course will provide adetailed explanation of ASTM D 5321,including detailed discussion of test pa-rameters. Procedural implications ofspecimen anchorage, normal stress ap-plication, machine friction and calibra-tion, rate of shear, and reportingmechanisms will be evaluated. In addi-tion, limitations of the D 5321 test willbe explored, with explanation ofalterna-tive tests. Special emphasis will beplaced on specifying a meaningful sheartest that will best serve the user.

Design and Construction ofSegmental Retaining Walls

Instructor:

G James G. Collin, Ph.D., P.E., TheCollin Group, Ltd., Bethesda, Mary-land, USA

This course will focus on the design andconstruction of segmental retainingwalls (SRWs). Participants will learnhow to design SRWs using the NationalConcrete Masonry Association (NCMA)Design Manual for SegmentalRetainingWalls. Items that will be covered with re-spect to design of SRWs include: evalu-ation of the long-term performance ofgeosynthetic reinforcement; calculationof the required connection strength be-tween segmental concrete units and geo-synthetic reinforcement; facing stabilityandhowtodesign facingstability intoanSRW system; internal stability includ-ing pullout and rupture of the reinforce-ment; and external stability includingsliding, overturning, and bearing capac-ity. In addition to the design of SRWs,the short course will focus on theconstruction of SRWs and importantconstruction procedures.

NSF Geomembrane State-of-Practice Paper andVision Paper Development Workshop (June/July 2000)

he National Science Foundation(NSF) and Auburn University

sponsored a workshop on GeomembraneState-of-Practice Paper and Vision Pa-per Development. The Workshop washeld for two full days at the Auburn Uni-versity campus in Auburn, Alabama,USA, on 30 June to 1 July 2000. IanPeggs (I-Corp International, Inc.) andDavid Elton (Auburn University) orga-nised the Workshop.

The purpose of the Workshop in-cluded reviewing the state-of-practicegeomembrane usage in solid waste dis-posal and liquid impoundment and de-veloping a vision for the future directionof the technology. Two reports will beprepared from the review results.

The following 12 professionals,from the solid waste disposal industry,participated in the meeting, which wasmoderated by David Elton of AuburnUniversity: Sam Allen (TRI Environ-mental), Glenn Darilek (Leak LocationServices), J.P. Giroud (GeoSyntec Con-sultants), Robert Haddox (Environmen-tal Protection Systems), Ian Peggs(I-Corp International, Inc.), Robert Pha-neuf (New York State Department of En-vironmental Control), Mark Sieracke(Serrot, Inc.), Richard Thiel (Thiel En-gineering), John Workman (Waste Man-agement, Inc.), and Ed Zimmel (GSELining Technology, Inc.).

The participants were selected fortheir expertise in the many facets of thegeomembrane solid waste disposal in-dustry — construction, ownership, ma-terial properties, liner manufacturing,inspection, testing, design, and govern-

ment regulation. The participation andvarying perspectives of the individualsfrom all of these areas generated very in-teresting discussions and resulted in aproductive meeting.

Workshop topics were selected bythe participants and the organisers. Thetopics included many items related togeomembrane seaming, leak detectionand repair, significance of small leaks,puncture protection, use of geomem-branes in bioreactors, avoiding destruc-tive seam testing, wrinkles, multiaxialtesting, and several other topics. Muchof the discussion involved the regulato-ry consequences resulting from changesin construction procedures and testingprotocols.

The Workshop organisers will pre-pare two reports from the meeting: oneon the State of Practice and one on re-search needs in this important area. Thefirst report will assist others in learningcurrent practices. The second is ex-pected to provide guidelines for the NSFin establishing priorities for researchand work in the area of geomembranesin waste disposal.

was the most recent in a series of verysuccessful Geo-Institute meetings. Geo-synthetic sessions were organised incooperation with the North AmericanGeosynthetics Society (NAGS), the IGS,and the Geosynthetics and Earth Rein-forcement Committee (TC9) of the Inter-national Society for Soil Mechanics andGeotechnical Engineering (ISSMGE).

The Conference commenced withseveral geotechnical short courses, in-cluding one instructed by R. Barrett, A.Ruckman, J.T.H. Wu, D. Leshchinsky,J.G. Zornberg, and M. Adams on geosyn-thetic-reinforced soil structures that waswell attended. For this short course, par-ticipants were shown the rudiments ofwall design and several innovative ap-plications. The following day, partici-

pants took an all-day field trip to severalski resorts andsmall townsin theRockiestoviewexamplesof innovativemechani-cally stabilised backfill walls and bridgeabutments.Yenter Companiessponsoredthe tour, which was guided by R. Barrett.

There were 84 technical sessionsheld at the Conference on a wide rangeof geotechnical topics, including sevenon geosynthetics. There were two ses-sions on advances in geoenvironmentalengineering, one moderated by J.Fanninand D. Elton and the other moderated byJ.G. Zornberg, B.R. Christopher, andJ.K. Mitchell. D. Leshchinsky and J.Otani moderated a session on advancesin reinforcement with geosynthetics.There were two sessions on monitoring,one moderated by D. Sandri and J. Paul-

son and the other by J.G. Zornberg, B.R.Christopher, and R.D. Holtz. J. Bowdersmoderated a session on geosynthetics inhydraulic systems.

Highlights of the program includedkeynote lectures by R.M. Koerner onlandfill failures and R.J. Bathurst ongeosynthetic-reinforced walls.

A total of 27 technical papers havebeen compiled in Geotechnical SpecialPublication 103, “Advances in Trans-portation and Geoenvironmental Sys-tems Using Geosynthetics”, which wasedited by J.G. Zornberg and B.R. Chris-topher and is available from the ASCE.

ics. R.D. Holtz, J.K. Mitchell, R.M.Koerner, and B.R. Christopher formedthe panel and each individual presentedtheir ideas on a particular aspect of thefuture of geosynthetics. Landfills,education, soil reinforcement, hydraulicconsiderations, and the need for moretesting were highlighted. These presen-tations spurred considerable audienceparticipation, particularly on the effica-cy of geosynthetics software and on theneed for monitoring wells arounddouble-lined landfills. It was generallyagreed upon that greater geosyntheticseducation is required.

The Geo-Institute GeosyntheticsCommittee held a meeting that was

Chaired by J. Bowders. Over 20 profes-sionals attended and participated in theCommittee’s planning process, whichincluded the development of futuretechnical sessions at conferences andpreliminary plans for geosyntheticseducation activities. The next Commit-tee meeting will take place at the GRI-14Conference to be held in Las Vegas, Ne-vada, USA, 15 to 16 December 2000.For information on this meeting, contactJ. Bowders (Tel: 1/573 882 8351, E-mail: [email protected]).

The Geosynthetics and Earth Rein-forcement Committee (TC9) of theISSMGE also held a meeting during theConference, under the coordination of

its Secretary, J. Otani. Activities dis-cussed during the meeting included on-going compilation of case histories,comparison of international guidelinesfor reinforced soil design, and geosyn-thetics education.

Geosynthetics System – Noise Barrier ApplicationMotorway A12, Netherlands

he new housing development ofVeldhuizen near De Meern, Neth-

erlands, is located next to MotorwayA12, one of the busiest motor routes be-

tween Utrecht and The Hague. To re-duce vehicular noise levels in the newhousing development, the city of Vleu-ten/De Meern planned a 10 m-highnoise

barrier with an additional approximate 3m-high wall on the wall crest. The noisebarrier runs parallel to Motorway A12and is approximately 1,500 m long. The

T


design, including the stability calcula-tions, was carried out by a consultingcompany in coordination with the hous-ing development owner.

The barrier was built with approxi-mately 650,000 tons of cinder from in-cineration plants. According to theDutch Guideline for ConstructionMate-rials the cinders may be considered as asecondary construction material. Whenusing this secondary construction mate-rial, various requirements for the protec-tion of the environment must befulfilled. For example, the law statesthat the incineration cinders must notcome into contact with groundwater.

The technical requirements for theentire project were stringent and weredefined as follows:

D The stability of the constructionmust be ensured in the long term.

D After final consolidation, the secon-dary construction material must be atleast 0.5 m above the averagehighestgroundwater level.

D No precipitation may get into the

noise barrier.

D An expert company should carry outthe sealing with approved materialsand in accordance with the quality-control measures.

One company was able to meet all of thenecessary requirements and wasawarded the contract to supply the entiresealing and reinforcement system.

The core of the noise barrier wallconsists of cinders. A composite seal,comprising a geosynthetic clay lineranda 2 mm-thick structured geomembranemade from chemically resistant high-density polyethylene, was installed di-rectly on the compacted cinders. Thestructure on both sides of the geomem-brane ensures the necessary friction per-formance in the shear plane.

Thepolypropylenenonwovenprotec-tiongeotextile(installedonthesealingsys-tem)hastwofunctionsin thisapplication:primarily,it servestosafelyprotect theun-derlyinggeomembraneagainstmechani-cal damage; and secondarily, it enables

seepage water to discharge from the top-soil layer.

To ensure the stability of the 1.5 m-thick top-soil layer and to take up theforces directed down the slope, a polyes-ter (PET) geogrid was installed. The res-in PET ensures a low creep factor. Themonolithic, extruded flat bars of thegeogrid have high tensile properties,even at ≤ 2 % elongation and ensure op-timum protection against on-site instal-lation loads. The geogrid also providesan immediate interlocking effect withthe top soil. For anchoring, the geogridwas embedded into the fill crest.

All of the geosynthetics used in thisconstruction project were manufacturedby the same company according to DINEN ISO 9001. Installation was carriedout by an installation company certifiedto ISO 9001. Approximately 1,000 m2/day was installed. The noise barrier wasconstructed in two sections: one 600 mlong and the other 900 m long.

provides practical solutions totoday’s environmental problems. A full-service, global, environmentalcompany, CETCOis backed by more than 70 years of bentonite miningand manufacturing experience. We are committed to providing qualityproducts that are both cost effective and sensitive to the preservation ofthe environment.

Our Lining Technologies Group is a leader in the field of geosyn-thetic clay liners (GCLs) and soil sealants. Bentomat and ClaymaxGCLs are bentonite and geotextile composites engineered for use in avariety of lining applications, including mining, solid waste, and reten-tion ponds.

GCLs provide an economical alternative to compacted clay linersystems. With a typical hydraulic conductivity of 5 × 10-9 cm/s, GCLsprovide seepage protection equivalent to more than 0.9 m of compactedclay. In addition, GCLs are economical and easy to install: simply un-roll and overlap to form a perfect seam.

CETCOoffers five standard GCLs: Claymax 200R and Claymax600CL, which are used for flat areas; Bentomat ST, Bentomat DN,Bentomat CL, and Bentomat CLT, which are used for designs requir-ing high internal shear strength.

The many uses of GCLs include:D Landfill liners and caps.

D Decorative and industrial retention basins.D Secondary containment for above ground and underground tanks.D Unique liquid retention applications.

CETCO’s seven sales groups are active worldwide. Our manufac-turing facilities, located in North America, Europe, and Asia, are sup-plemented by a global distributor network. So, wherever you are lo-cated, there is likely to be a local CETCO office or distributor nearby.

CETCO’s GCLs offer several advantages over traditional com-pacted clay liners — improved hydraulic performance, easier installa-tion, and use of less air space within a landfill. Because of their uniqueself-healing sodium bentonite base, our liners resist cracking that typi-cally occurs in compacted clay liners subjected to repeated freeze/thawconditions. CETCO’s patented manufacturing process utilises a needle-punched technique that encapsulates sodium bentonite between twolayers of geotextile, inhibiting migration of the clay in its dry or hy-drated state.

CETCO’s sodium bentonite is also used in slurry wall applications.CETCO also offers chemically treated soil sealants that can withstandcontact with both contaminated and uncontaminated water.

Through testing conducted at our on-site laboratory, we will deter-mine the correct technology and application rate to meet your project’sspecial needs.
