Highway asphalt thickness
Web• Roadways can have an asphalt thickness of as little as four inches or as much as 12 inches. It all depends on the type of street or highway, the loads it will bear, and whether the asphalt is applied over an aggregate base. • Asphalt overlays are normally less than three inches in depth, especially if they are installed over a concrete pavement.
