Abstract: The amount of plastic waste in India is reaching a gigantic scale. Wastes from household, industries and medical facilities contribute towards this. As the plastic waste is a cause of various environmental and health hazards, its proper management that leads to an effective reuse or disposal is a concern for the Government and civic bodies. Waste plastic, when added to hot aggregates, forms a fine coat of plastic over the aggregates and such aggregates, when mixed with the binder is found to give a mix that has higher strength and resistance towards the deteriorative actions of water. Thus, (the bituminous Roads using waste plastic in the wearing course) also called as plastic roads are now gaining popularity in India. With the Indian Road Congress bringing out a code of specifications on plastic roads (IRC SP: 98 -2013), many agencies are coming forward to implement plastic roads in India as it is a sustainable method and also need of the hour. However, for a large scale implementation, the performance and longevity of these roads need to be evaluated comprehensively. This paper presents the various properties of bituminous mix with 8% waste plastic when compared with normal bituminous mix with the help of a comparative case study. In Pune, Maharashtra, India ten city roads which were overlaid with normal bituminous mix and ten roads which were overlaid by bitumen mixed with shredded waste plastic were studied for their performance over duration of two years from the time of laying of the overlays. Laboratory experiments and on- field tests were carried out to evaluate their functional and performance characteristics after they were opened to traffic. The results report an improved performance of plastic roads over the conventional ones.
