Flexible pavements are mostly adopted pavements for transportation. To give a better service the subgrade lying underneath the pavement should have good bearing capacity, strength and stability. Subgrade is one of the important components of the pavement which is constructed by the natural soil. It is a compacted layer of soil provide the lateral support to the pavement.
