Hot mix asphalt is a type of paving material made from a mixture of aggregates, such as sand and gravel, combined with a binder, typically asphalt cement. This mixture is heated to high temperatures, usually between 300°F and 350°F, to ensure proper workability and adhesion. It is commonly used for constructing roads, parking lots, and driveways due to its durability and smooth finish. The production of hot mix asphalt occurs in a batch plant or drum plant, where the materials are combined and heated. Once mixed, it is transported to the construction site while still hot, allowing for easy application. After being laid down, it cools and hardens, creating a strong surface that can withstand heavy traffic.
