Study On Utilization of Plastic Waste in the Construction of Flexible Pavement

Abstract

Plastic waste is a common problem nowadays. Plastic waste material which we can reuse by certain processing and use in road construction. Plastic is a toxic and perpetual material. Disposal of waste plastic is a menace and become a serious problem globally due to their non-biodegradable and very harmful to human health’s since they are not disposed scientifically and then create a ground and water pollution. Wrappers of betel nuts, chocolate, chips, handbags, cold drink bottles and all other forms of plastic create significant environmental and economic problem Temperature varying among 120ºC – 160ºC gives the softening point of these plastic. They do not produce any toxic gases during heating but the softened plastics have inclination to form a lamination or coating over the aggregate, when it is sprayed over the hot aggregate at 160ºC. A detailed study on the performance of these roads shows that the construction with PCA Bitumen mix is performing well. This process is eco-friendly and economical too. By this process a road of 1 Km length and 3.375M width of single lane can consumes 100000 carry bags and the road strength is improved by 100% and there found no any pot hole.
