Soil stabilization is one of most important for the construction which is widely used in connection with road
pavement and foundation construction because it improves the engineering properties of soil such as strength, volume
stability and durability. In the present investigation is to evaluate the compaction and unconfined compressive strength of
stabilized black cotton soil using fine and course fly ash mixtures. The percentage of fine and course fly ash mixtures which is
used in black cotton soil varied from 10 to 30. In the study concludes that with percentage addition of fine, course fly ash
improves the strength of stabilized black cotton soil and exhibit relatively well defined moisture-density relationship. It was
found that the peak strength attained by fine fly ash mixture was 25% more when compared to course fly ash
