Asphalt concrete is a composite material commonly used in the construction of roads, parking lots, and airport runways. It consists of a mixture of aggregates, such as sand and gravel, combined with a binder, typically asphalt, which is a petroleum product. This combination provides a durable and flexible surface that can withstand heavy traffic and varying weather conditions. The production of asphalt concrete involves heating the asphalt to reduce its viscosity, allowing it to coat the aggregates effectively. Once mixed, the material is laid down in layers and compacted to create a smooth, even surface. Its properties make it a popular choice for infrastructure projects worldwide.
