Asphalt is a black, sticky substance that is commonly used in road paving and roofing. It is a mixture of aggregates, such as crushed rock, sand, and gravel, and bitumen, a petroleum-based binder. Asphalt is produced in asphalt plants, where the aggregates are heated and mixed with hot bitumen, then transported to the construction site where it is spread out and compacted to create a smooth, durable surface. It is also used in the construction of parking lots, driveways, and airport runways.
