Description
Vishal Dhiman, with three colleagues, reports a 2026 trial of road surfacing made with rubble from torn-down concrete. India builds roads fast and dumps much of this waste, which harms land and water. The team asked whether treated waste chunks could serve in the top layer of a road, the part tyres touch.
The waste was pre-coated with bitumen emulsion, a tar-like binder in water, to boost grip and water resistance. Tests varied binder share, waste share, and heat level, and a surface method found the best mix. At about 4.79 percent binder and 21 percent treated waste, the mix met national specs for strength, stiffness, and water resistance. The authors say treated rubble can replace some fresh stone and cut dumping at the same time.
