Plastic Roads As An Alternative Solution To Solid Waste Management: A Review

Plastics are one of the most abundant material found across the globe. Due to the rapid urbanization and over population, the usage of plastics increased dramatically. The handling of municipal plastic wastes has always been a big problem to the society. These plastic wastes lead to steep increase in various types of pollution. The disposal of municipal plastic waste has become more difficult process than its production. Many researches across the globe have proven that these plastic wastes can be use in specific proportion along with bitumen in the laying of roads. The wastes are grounded or shredded into powder; nearly small quantity of plastics is blended with the bitumen by suitable techniques like dry/wet processes. By this process, road life has increased significantly. Due to this there would be a notable reduction in level of plastic waste generated. This paper reviews about the various types of plastics such as e - plastic wastes, municipal plastic wastes etc., used for the construction of roads. The composition, durability, strength, economy of road construction and the comparative results of bituminous and plastic-mixed road have been discussed in this paper.
