In India, engineers coated road aggregate with shredded plastic before adding bitumen; an NH-207 test track reported satisfactory performance

Engineers in India tested a road-building method that uses shredded waste plastic to coat heated stone aggregate before bitumen is added, and one of the major field trials was carried out on National Highway 207 in Karnataka, where a 20-kilometre test section compared several modified bituminous binders, including a waste-plastic formulation. The Ministry of Road Transport and Highways later described the waste-plastic section as showing satisfactory performance.The process tested in India is kn
