Evaluation Studies on flexible pavement system were carried out by using the different reinforcement materials in the fly ash sub base courses laid on expansive soil sub grades. It was observed from the laboratory test results of direct shear and CBR, that the optimum percentage of waste plastics is equal to 0.4% for fly ash materials. Cyclic load tests were carried out in the field by placing a circular metal plate on model flexible pavements. It is observed that the maximum load carrying capacity associated with less value of rebound deflection is obtained for geo grid reinforced stretch followed by bitumen coated bamboo mesh and waste plastics reinforced stretch in the flexible pavement system laid on expansive sub grades.
