Abstract:

The growing cost of traditional stabilizing agents and the need for the economical utilization of agricultural wastes for beneficial engineering purposes has prompted an investigation into the stabilizing potential of RHA & SCBA in highly expansive soil. This research work is aimed to evaluate the suitability of RHA & SCBA for stabilization of expansive soil. The laboratory work involved index properties to classify the soil sample. The preliminary investigation of the soil shows that it belongs to MH class of soil by USCS A-Line Chart soil classification system. Soils under this class are generally of highly expansive & poor engineering use. Atterberg’s limits, free swell index, compaction, CBR and UCS tests were used to evaluate properties of stabilized soil. In this project an attempt has been made to study the compaction, CBR and UCS characteristics of expansive soil blended with different percentages of RHA and SCBA in a view to determine the optimum percentage. These test results shows that stabilization of expansive soil with agricultural by-products (RHA & SCBA) enhances the strength.
