The Asphalt Manufacturing Process Explained

Getting the Right Asphalt Mix. There are a few different ways to mix asphalt, the most popular of which are hot and cold. Hot-mix asphalt is made by heating aggregates to decrease the viscosity of the binding agents and make the whole more fluid, then drying it to remove any remaining moisture. It is mixed hot at 200-350 degrees Fahrenheit.
