Soil stabilization is the alteration of soil to enhance their physical properties. The process of soil stabilization helps to achieve the required properties in a soil needed for the construction work. Weak soil generally swells and shrinks depending upon the presence of moisture content. Stabilization can increase the shear strength of a soil and control shrinkage properties of a soil and thus improving the load bearing capacity of a soil. In this project red soil is collected. Generally, red soils are low expansive soil having average strength and low bearing capacity. The weak soil mixed with different percentage of MSWA with different percentage of 2.5%, 5%, 10%, 12.5% and 15%. Liquid limit test, Plastic limit test, Standard proctor test were conducted on soil stabilization. Finally, the index properties and Compaction values of soil to be improved.
