Enhancement of load carrying capacity and shear strength of soil has been improved by soil stabilization. The largely used soil stabilizing agent is fly ash, the waste from coal-fired power plant, which is produced over 100 trillion each year creating thoughtful dumping as well as ecological complications in India. Sugarcane bagasse ash is a fibrous residue of sugarcane stalk that remains after extraction of sugar, when incinerated gives the ash. The present investigation made to weigh up the efficiency of silty sands blended with sugarcane bagasse ash and fly ash for soil stabilization. CBR and Standard Proctor Test are carried out on samples primed from fly ash admixed soil modified through sugarcane bagasse ash. Samples prepared by means of 2% sugarcane bagasse ash content with fly ash content varying from 0% - 20% along with an increase of 5% by the dry mass of soil. In addition to fly ash the specific gravity and MDD are decreased with increased in OMC.CBR value of unsoaked and soaked sample was maximum with increase of 86% and 55% respectively at 5% FA + 2% SBA.It is noticed in these tests that stabilization of soil using sugarcane bagasse ash along with fly ash improves the strength as well as effective to reduce the negative impact of agricultural plant and coal-fired power plant waste by product on environment.
