The road that replaces asphalt.
Karbon Yol is a bitumen-free, carbon-based road surfacing system developed in Türkiye.
How it works
In asphalt, bitumen holds the aggregate together and the road hardens as it cools. In Karbon Yol, active and reactive carbon interact with chemical binders, and the surface hardens through chemical bonding and setting.
No aggregate drying and no high-temperature mixing are required.
Mobile Carbon Reactor
A truck-mounted mixing and feeding unit prepares the material on site, without added heat. It needs no dryer drum, burner or bitumen tank.
