Plastic is a toxic & persistent material. It is generally found to be nearly 5% in Municipal Solid Wastes (MSW) which is a major environmental threat. Nowadays, plastics are used in our day-to-day life for enormous purposes viz. carry bags in various shops, plastic sheet materials for making roofs of temporary kutcha houses and hutments, packaging materials in LDPE & HDPE manufacturing industries, in drinking water supply and sanitary appurtenances, in electrical appliances, in manufacturing of various electronic appliances etc. The outcome of Life Cycle Assessment (LCA) of these plastic materials is not satisfactory. Generally people dispose off these plastic materials and plastic products after their usage on open ground as surface impoundment in lieu of their reuse, recycle and reduction in volume which has become a prominent ecological & environmental problem. Waste plastic bags & waste plastic materials interrupts the infiltration and percolation of rain water through soil pores and in turn diminishes the ground water recharge in aquifers. Nowadays we have tones of plastic solid wastes in our surroundings. There are so many institutes which after consistent researches have come to a conclusion that waste plastics can be used in modifying roads. If we use plastics in road construction, we can reduce the cost of road construction and pollution index of environment to an appreciable extent. We can use plastics as binder with bitumen. It may give better finish-ability, stability, binding property, resistance to water and durability.
