Use of Plastic Waste in Flexible Pavement-Green Highway

Abstract

Today, plastic waste and its disposal Such as wrappers of chocolate, chips, carry bags, cold drink bottles and all other forms of plastic create significant environmental and economic problems. These forms of plastic consume massive energy-depleting in the environment in various ways. So manufacturing firms and construction industries, the use of plastic is a priority to handle and pack things comfortable due to its lightweight, effectiveness cost, and strength. The plastic waste used is poly-ethylene, poly-styrene, poly-propylene, the temperature varying between 120oc 160oc gives the softening point of these plastics. The plastic waste is shredded & coated over the aggregate and mixed with hot bitumen and the resulted mix is used for pavement construction this mix will not only strengthen the pavement and also increases its durability. The main objective of this paper is to discuss the importance of plastic in terms of cost reduction, increases the strength and durability when these plastics are heated and coated upon the aggregates to reduce the air voids with plastic and binds with aggregate to provide stability. It’s economical and eco-friendly. Keywords—Flexible pavement, aggregate, plastic waste, plastic modified bitumen and plastic modified aggregate
