How thick should hot mix asphalt top coat be?

The thickness of a hot mix asphalt top coat typically ranges from 1.5 to 3 inches, depending on the intended use and traffic load of the surface. For residential driveways, a thickness of about 1.5 to 2 inches is often sufficient, while commercial applications or roads may require a thickness of 2 to 3 inches to ensure durability and performance. Proper compaction during installation is also crucial to achieve the desired thickness and longevity.
