Black cotton soils have frequently subjected alternate swelling shrinkage, which gives differential settlement to buildings. In this study Tea Waste (TW) used as partial replacement of black cotton soil with proportions of 2.5 %, 5 %, 7.5 % and 10 %. Soil sample behaviour was observed by Compaction test, California Bearing Ratio (CBR) test, Liquid limit test, Plastic limit and specific gravity Test. The Maximum dry density and Optimum moisture content were decreased when proportion of Tea Waste is increases. When Tea Waste (TW) is mixed with the expansive soil, the Plastic limit and liquid limit decreases by mixing tea waste, which decreases plasticity index. Addition of Tea Waste resulted in appreciable increases in the CBR of the soil and got maximum @ 5 % Tea Waste (TW) with soil. CBR value was increased by 7.68 % at 5 % Tea Waste with soil.
