U.S. Engineers Use Recycled Glass, Tires, and Toner to Enhance Road Construction
Recent engineering projects across the U.S. demonstrate innovative uses of recycled materials in road construction. Michigan Technological University found that adding 6% surface-treated waste glass to asphalt improves stability and anti-skid performance. Arizona used ultra-lightweight foam glass from recycled bottles to widen Interstate 17 without overloading old culverts. Pennsylvania incorporated 5,570 tons of shredded tires as lightweight fill in bridge approaches, enhancing drainage and reducing soil pressure. Additionally, a Texas study showed that adding 10% waste toner to asphalt binder increases durability and stability, highlighting sustainable infrastructure advances.
