Abstract-There is a need to stabilize expansive soil such as black cotton soil in order to mitigate the inherent deleterious property of swelling and shrinking. For effective utilization of soil as subgrade it has to be stabilized and more importantly at a relatively cheap cost. In this project an attempt is made to stabilize the soil with locally available material. For this investigation 5, 10, 15, 20 and 25% of Cashew nut shell ash was added to the Black cotton soil while keeping the Lime percentage at 5% for all mix ratios. Experimental tests conducted in this research includes: Atterberg’s limits, Specific Gravity, Standard Proctor Compaction, Unconfined Compressive Strength, California Bearing Ratio (CBR).Tests were carried out to determine the optimum percentage of Cashew nut shell ash and Lime. Results obtained after the test shows that there is marginal improvement in the CBR and UCS value. Results of Compaction, Unconfined Compressive Strength, California Bearing Ratio (CBR) tests indicate that combination of 20% Cashew nut shell ash + 5% Lime is better for stabilizing the Black cotton soil.
