Abstract - The foundation soil supports structure loads. Much of India is covered in red soil. These soils are found in low-rainfall locations yet cannot store moisture. Subgrade dirt greatly affects pavement stability. The mineralogical makeup of expansive soil causes it to expand and shrink in wet and dry circumstances, despite its strength. Concerns for problematic high plastic expansive subgrades include reducing stabilizing costs and improving soil load bearing capacity. This experiment examined the use of bagasse ash and crushed granulated blast furnace slag as soil stabilizers to improve subgrade. Ground Granulated Blast-furnace Slag and Sugarcane Bagasse Ash stabilize red soil in this study. The first step of the experimental study determined soil physical parameters as grain size distribution, Atterberg limits, Standard Proctor test, California Bearing Ratio, and Unconfined Compression Test. In the second phase, red soil was tested with 0%, 10%, 20%, and 30% Ground Granulated Blast-furnace Slag to determine its optimal dosage. In the final phase, the soil was treated with 10%, 20%, and 30% Sugarcane Bagasse Ash and Standard Proctor test to determine its California Bearing Ratio.
