In countries like India, rapid industrialization coupled with limited available land has led to a growing demand for the utilization of industrial waste materials. From a geotechnical perspective, various industrial by-products such as fly ash, granite and quarry waste, cement kiln dust, silica fume, and rice husk possess advantageous properties ideal for soil stabilization purposes. Utilizing these waste materials for stabilization is a viable method for enhancing the engineering properties of soil and rendering it suitable for construction applications. This paper provides an overview of recent trends in the stabilization of expansive soil using Fly ash and stone dust to improve the index properties of black cotton soil, aimed at mitigating environmental risks associated with soil instability. In this research work 5,10,15% of fly ash along with the variation of stone dust 10,20,30% is added to the soil for stabilization. The Standard proctor test, Grain size analysis, Liquid limit (LL), Plastic limit (PL), Specific Gravity and Free swell Index (FSI) were performed on black cotton soil. The MDD value for soil is 1589.65 kg/m3 which is increased to 1842.89 kg/m3 with the addition of 15% fly ash and 30% stone dust, and the OMC value of soil was 21.97% which was decreased to 16.23% with the addition of 15% fly ash and 30% stone dust. The liquid limit of soil was initially 87% which was reduced to 44.7% with the addition of 15%FA and 30% SD. The plastic limit of soil was initially 38.29% which was reduced to 24.48% with the addition of 15% FA and 30% SD.
