Effect of Soil Stabilization on Subgrade Soil Using

2020-3-24  Soil stabilization is the process of developing the durability and strength of the subgrade soil in which the physical properties of the soil are changed. It is important that the process of soil stabilization should be cost-efficient, eco-friendly, and gives optimum results. For all engineering projects, it is strongly recommended to increase the soil strength to extend the service life of the structures and reduce the thickness of the pavement layers (Rajoria Kaur, 2014). After the stabilization of the soil, the Unconfined Compressive Strength (UCS), California Bearing Ratio (CBR) values, and the soil
