Soil Stabilization can be done in many ways. Soil Stabilization is mainly done to improve the strength of soil and bearing capacity of sub grade soil. Geo grid is most used stabilizer in stabilization of soil in flexible pavements. Geo grids are mainly used for reinforcement of soils for different kind of works in construction. In this work, the main discussion is about the stabilization of black cotton soil in flexible pavements by using geo grids. The increase in CBR value of black cotton soil by using geo grid determines the increase in strength of black cotton soil in flexible pavements.

Keywords : Geo-grids, black cotton soil, CBR test.
