Abstract:

Soil is a base of structure which actually supports the structure from beneath and distributes the load effectively, If the stability of the soil is not adequate then failure of structure occur in the form of settlement, cracks etc, Expansive soil like black cotton soil are more responsible for such situations and its due to presence of montmorillonite minerals, which has ability to undergo large swelling and shrinkage. To overcome this problem, the properties of soil must be improved; soil stabilization is effective technique that addresses this problem by alerting the properties of soil. The present study deals with the stabilization of black cotton soil using scrap rubber tyre powder. The admixture i.e., scrap rubber tyre powder is blended with unmodified soil in varying different percentage of 0%, 5%, 10%, 15% & 20% to obtain the optimum percentage of admixture required for soil stabilization. The result show that maximum Dry Density and CBR values are improved after addition of scrap rubber tyre powder to the soil. In this comparative study laboratory tests such as Atterberg’s limits. Compaction test and CBR tests were carried out.
