Sustainable Use of Waste Plastic Materials to Strengthen the Adhesion Properties of Viscous Grade Asphalt Mixtures

It is not new to use polythene in road construction. Some aggregates are highly hydrophilic (water loving). Like bitumen, polythene is also hydrophobic (water hating) in nature. So the addition of hydrophobic polythene by dry or wet mixing process to bituminous mix lead to improvement of strength, water repellent property of the mix. Polythene gets added to hot bitumen mixture and the mixture is laid on the road surface like a normal tar road. In the Plastic roads we use plastic carry-bags, disposable cups, polythene packets that are collected from garbage as important ingredients of the construction material. To improve the fatigue life, reduce the rutting & thermal cracking in the pavement it is necessary to go through polymer modification processes. There are series of tests carried out in the laboratory to ascertain the suitability of bitumen as main material in pavement design. The raw materials used in this investigation were locally available and these include bitumen of VG-10, VG-20, VG-30,VG40 grades, aggregates of size 10 mm, and plastic waste like plastic bottles, plastic bags. The Percentage of Plastic waste added to bitumen is 5 %, 10%, 15%, 20%. Various Tests performed to know the performance of plastic waste bitumen compared to normal bitumen
