In the present world we are all aware of this thing that commercial-vehicles and the private vehicles are in the rate of increment day by day and with the vehicle’s increment the load of bearing on the soil will grow more. So, when the typical wheel load on the soil of sub-grade will grow more the conditions of the stresses will also grow more. So, if this sub-grade has low capacity of bearing the loads it will fail in that case and if we have to make this type of soil well suited for sub-grade construction we will have to stabilize that soil with the help of materials like Bagasse Ash (Sugarcane ash). After adding these materials in the soil there is change in soil’s physical and chemical properties. We will see the result and analyze that there is change in the geo-technical properties of the soil. We will find out that the liquid limit and the plastic index of soil will decrease but the value of C.B.R will have some increment. In this research paper we are using Bagasse ash (Sugar-cane ash) from Wahid industries, Phagwara, and after performing tests till now we have observed that the value of M.D.D decreases from 1.86 to 1.825gm/cm3, as we have increased the amount of Bagasse ash in our soil samples. We have done the stabilization by using different concentrations of Bagasse ash i.e. 2.5%, 5%, 7.5%&10%. While performing the sieve analysis of the soil sample it was seen that soil is poorly graded soil and the liquid limit will decrease from 24% to 21% after addition of Bagasse ash in it and our main purpose is to see that with the usage of Bagasse ash as admixtures in the sub-grade soil will decrease the thickness of the pavement and decrease the overall cost. The test of C.B.R was being done and the result was being analyzed by me and was seen that total thickness of the pavement will decrease from 809 mm to 550 mm and the value of C.B.R is coming maximum at 7.5% replacement of Bagasse ash. Key words: Local soil available, Bagasse ash, Stabilization.
