FLEXIBLE PAVEMENTS FOR WASTE PLASTIC DISPOSAL

Plastic comprises of five percent of municipal solid waste. Disposal of such waste materials has become a serious problem. These wastes are not only nonbiodegradable but also create environmental and hygiene concerns. Plastic has been used effectively in the construction of flexible pavements. In India several million metric tons of waste plastic is generated every year. If these waste plastics are used suitably in road construction, then the disposal and environmental problems can be addressed to a large extent. Utilization of plastic in bituminous mix enhances the properties of mix. Plastic is shredded and mixed with bituminous concrete. This not only strengthens the pavement but also increases the life of the pavement. In the present study plastic waste is being used in bituminous mixes and the strength characteristics are studied
