USE OF POLYMER MODIFIED BITUMEN IN FLEXIBLE PAVEMENT: A REVIEW

Abstract

The use of plastic materials such as carry bags, cups etc. consistently increasing day by day. Due to excessive use of polythene in day-to-day life, the pollution to the environment is enormous. Discarded thin plastic carry bags are means in town. The clog drains, because flooding, choke animal’s intestines that eat them and are unsightly steppe across fields; they block generation and prevent rain water absorption by soil. Recycling plastic by the melting release fumes. toxic contents might leach in the recycled water bottles. Plastic materials lack the quality of bio-decomposition thus leaving them to non-option against being land filled or combusted as it is both of this process is unhealthy to environment, hence leading contamination of air and land. Since the polythene are not bio-degradable, the need of the current hours is to use the waste polythene in some beneficial process. The quality of bitumen can be improved by modifying the rheological properties of bitumen by blending with polymers like plastic waste. The use of plastic waste in the modifying the bitumen proves eco-friendly. The main aim of this paper is to focus on the using available plastic waste present in abundant which can be used economically and conventionally in bituminous road construction.
