Effect of PolyCom admixture on Geotechnical Properties of Black Cotton Soil

Over the past few years to stabilize the clayey soil which has been generally adopting these days in developing paved and unpaved roads, cement based products such as soil cement, and different kind of materials like lime are used. These additives being used in soil improves the strength, durability and workability of soil and generally it leads to a thickness reduction of the pavement layers. Regrettably, boundless amount of conventional additives are required to strengthen the soil used in pavements which leads to relatively long curing time. The compaction action should be completed within the stipulated time period, because which significantly affects the construction costs. The other disadvantages associated with cement stabilized layers can be the shrinkage cracks developed which reflect rapidly through asphaltic surfaces and cause greater deterioration. Therefore the development of polymeric based additives has been of particularly interest as they demonstrate many added advantages; such as their ability to reduce permeability, increase durability, allow non time depending during the mixing stage and provide increased flexibility. In this project PolyCom is being used as additive from the list of various Polymer Stabilization Materials. The advantage being selecting PolyCom as it does not create a chemical reaction and is not a rigid setting agent. Black cotton soil was taken in the analysis and it is added with PolyCom to find out the changes in the properties and from the inference of results it was observed that PolyCom addition enhances the Geotechnical properties of soil when compared to the black cotton soil used alone as a stabilized material.
