Stabilization is the process of physical and chemical alteration of soils to enhance their engineering properties and thus improving the load-bearing capacity of a sub-grade or a sub-base to support pavements and foundations. Sodium chloride has been used for many years as a stabilizing admixture in selected base course materials. Sodium chloride added to raw soil were found to have negligible effects on soil plasticity while increasing compacted density and decreasing optimum moisture content. In this project, the stability of soil is found out by adding Sodium chloride (Nacl) and thus compared with the stability of soil without adding Sodium chloride (Nacl) followed by different laboratory tests.
