In this study, fly-ash is used as a stabilizing material to stabilize the expansive soil dealing with engineering characteristics as the parameter for it. Present paper describes a study carried out to check the improvement in the properties of expansive soil with fly-ash in varying percentages. Fly-ash is added in 10%, 20%, 30%, 40%, 50% and the change in index properties and engineering characteristics is examined. It has been found that significant variation in liquid limit, plasticity index, and swelling index. In expansive soil, liquid limit decreased from 55.2% to 36.3% and plasticity index decreased from 27.1% to 18.1% , differential free swell (DFS) also reduced from 52% to 14% respectively .the compaction test results showed increase in optimum moisture content (OMC) from 19% to 23% and decrease in maximum dry density (MDD) from 1.63g/cc to 1.52g/cc. Test result indicates that fly-ash has a potential to improve the properties of black cotton soil.
