Evaluation of Bituminous Layers Bond Strength Date of Start : December 2010 Date of Completion : On-going L&T ECC, LTD (R.I)Scope and Objectives In recent times there has been a notable increase in the slippage cracks on high volume highways, expressways and runways. In runways the areas subjected to high breaking and turning have been found to be prone to slippage cracks. In highways and in particular at ghat road section with curves, top layers experiences high breaking and turning forces. The slippage cracks mainly occur due to poor bonding between the asphalt layers. The bonding between the pavement layers is achieved with application of sufficient quantity of asphalt emulsion tack coat. The lack of testing procedures to evaluate the bond strength between layers, often leads to the use of inferior quality material as binding agents leading to bond related cracks and failure. Therefore, there is a need to develop and regularize a test procedure to determine the bond strength between various pavement layers. Larsen and Toubro Construction Research and Testing Centre (LTCRTC) had taken up the task to evaluate a runway portion with slippage cracks. The bond strength between the DBM and BC layers were evaluated with the in-house developed bond strength set up. Further to study the effect of tack coats, the same set up was also used to evaluate few laboratory prepared samples. ROAD RESEARCH IN INDIA 2010-11 15Methodology Bituminous core samples with intact DBM and BC were obtained from the distressed and non-distressed areas of the runway or a pavement. The samples were evaluated for their dimensions and density. The LTCRTC developed bond strength set up was used to determine the bond strength of the specimen. The set up had arrangement to keep the DBM part ofthespecimenfxedandtheBCportioncouldbe sheared. The BC portion was loaded circumferentially at the rate of 1mm/min till the specimen failed at the interface. The maximum load at failure is recorded and used to determine the bond strength of the specimen. Laboratory samples were also prepared using Marshall Compactor with rapid setting emulsion as the bi nder between the DBM and BC layers.Conclusions The specimens were found to fail at the interface. The average Bond strength of the core samples was found to be around 0.6 MPa. As per International practice bond strength of 1.0 MPa has been found to be adequate for critical sections of runways where as a bond strength of 0.5 MPa has been found to give good performance for highways. Samples prepared with emulsion as bonding agent were found to be dependent with minimum curing period. Some emulsions even after 28 days of curing have not improved the bond strength beyond 0.2 Mpa. Some laboratory samples have been evaluated with some mechanical interlocking grooves, which can enhance the shear strength properties at the intersection.Recommendationsforfurtherwork/furtherproposedwork Bond strength depends on climate conditions and the application process. Due to high wind and crude methods of application will not be able to yield better bond properties. Guidelines on tack coats in terms of mechanical properties will be very essential to improve the service life of highways.

Laboratory evaluation of constituent materials i.e mineral aggregate, fllers, SMA additive, bitumen and bitumen emulsionwere carried out to determine engineering properties. Test samples were prepared at varying concentration of fy ash to fnd out the mechanical and engineeringproperties of bituminous mixes. Optimum concentration of fy ash and binder content in different bituminoussurface treatment has been ascertained though laboratory detailed studies.FurtherFindings/Conclusions/SupportingData Pondashcanbeusedasfllerforbituminousroadconstruction. Pond ash can be used upto 5 percent as partof mineral aggregate for semi dense and dense bituminous concrete. However, usage of ash may be in the range of 8-10 percent for microsurfacing and stone matrix asphalt. Optimizedmixeswithashasfllerinplaceoflimeled to about 0.2 percent lesser bitumen content, which amounts to 4-5 percent saving in bitumen consumption. Use of ash as fller in SDBC,BC and SMA mixenhance resistance to moisture sensitivity of mix as evident from higher value of indirect tensile strength ratio and retained Marshall stability, after conditioning Marshall specimen in water. Cold mix SDBC containing 5 percent ash indicates acceptable values of stability and volumetric properties. Cold mixed micro-surfacing containing 8 percent ash and 9 percent latex modified emulsion meet requirement of specification given in IRC:SP:81-2008.Limitations of Conclusions or Interim ConclusionsBituminous mixes containing ash are slightly susceptible to rutting.Recommendations for further work Full scale performance studies are needed for hot mixed SDBC, BC and SMA as well as cold mixed SDBC, BC and Micro surfacing for framing standard guidelines and specifcations.Recommendations for Discussion/ Revision ofCodes/SpecifcationsNeedofIRCGuidelinesandfullscalefeldtrials.Furtherinformation/copyofreportcanbeobtainedfromDr. P.K.Jain, Chief Scientist & Head, Flexible Pavement Division, CSIR-Central Road Research Institute, New Delhi- 110 025.B.

Use of Coir Geotextiles in Road Construction Date of Start : April 2010 Date of Completion (Targeted) : March 2012 National Transportation Planning and Research Centre (R) ROAD RESEARCH IN INDIA 2010-11 17Present Status and ProgressLaboratory experiments were conducted on weak soil reinforced using natural geotextiles like coir mattings with different mesh size (half inch and one inch), panama weave (commercial name given by manufacturer) and also polymeric geotextile viz. High Density Poly Ethylene (HDPE). The improvements in soil properties obtained with the use of coir geotextiles were found out. It is proposed to lay test tracks and canal bank protection using biodegradable geotextiles like coir. The performance of the same will be monitored and evaluated.FurtherFindings/Conclusions/SupportingDataBy providing geo-textiles the CBR value of weaker sub grades could be enhanced. Thereby, the pavement layer thickness can be considerably reduced and this facilitates the construction of roads in poor sub-grade soil areas.Limitations of Conclusions or Interim ConclusionsPerformance studies have to be conducted on test tracks and canal bank protection constructed using biodegradable geotextiles like coir. The performance of the same has to be monitored and evaluated. Also studies are to be conducted regarding the useful age of these biodegradable geotextiles like coir.Furtherinformation/copyofreportcanbeobtainedfromDirector, National Transportation Planning and Research Centre, Sasthra Bhavan, Pattom Palace P.
