Abstract: Black cotton soils have posed challenges and difficulties in the construction activities because of their shrink and swell behaviour. These soils are not suit for construction activities due to low strength on wetting to overcome this improvement of soil can be done by stabilization. Therefore, it is necessary to properly choose the stabilizer for the economics of the process and considering environmental aspects. Rice Husk Ash is an Agricultural Industrial Waste produced by burning of Rice Husk a residue of milling of paddy. In India it is found abundantly and is a pozzolanic material that could be potentially used in various geotechnical aspects. In this paper different percentage of RHA and lime mixes were added to the soil and tests like plasticity, swell potential, permeability and UCS were performed. From the test results it is identified that addition of lime decreases plasticity and improves strength characteristics. Addition of RHA+ lime makes the expansive soil non-plastic, non-swelling and leading attain high strengths.
