Transportation is one of the major necessities in the development of country for effective transfer of goods and services, men, machinery from one place to other. It is well established fact that roadways serve as the major constituent for effective transportation. As India is rich in various soil deposits expansive soils creates a big problem for the laying of pavements because of its volume change at different climatic conditions. As the strength of the pavement depends upon its beneath layers, sub grade in expansive soils is rich in clay and silt content. So, for stabilization purpose fly ash is added as partial replacement and an additive of bitumen coated bamboo mesh is placed at 4 different layers in the sub grade is observed to be stabilized with optimum moisture content and maximum dry density. The prepared sub grade is observed to have high CBR values when compared with the CBR of unmodified soil.
