Asphalt is a black, sticky mixture used in road construction. This mixture is prepared by combining natural materials such as stone, sand, and gravel with a dark-colored binding agent called “bitumen.” When heated to a liquid state, asphalt is poured onto the road surface and then compacted and leveled using heavy rollers. Once hardened, it forms a strong surface suitable for vehicle traffic.How Is Asphalt Made?Asphalt production begins with mixing various natural materials in specific proportio
