Roads are the arteries through which Indian economy grows. India is a country which is having a coastal line of 7516.6 km. This coastal region mostly consists of marine clay deposits. For the construction of roads, using of locally available materials and soils will be economical. But in coastal region using marine clay (locally available) as a subgrade will not yield desirable results due to its poor engineering properties. Replacing soil is not economically feasible as it increases the budget of the project. Stabilization of the existing soil is a possible solution in such cases. Lime is a commonly available chemical and sawdust is a waste product from wood and timber industry. The study of using the above materials for the stabilization of marine clay is discussed here.
