Highways made of recycled plastic? Recently a California company used recycled PET scrap in place of asphalt along a California highway. They used glycolysis to depolymerize PET scrap for use in an asphalt binder. The pavement it produces is stronger than traditional hot-mix asphalt. Could this be the future of asphalt?
