how many inches of asphalt should a commercial driveway have
Asphalt Driveway Thickness How Thick Should An Asphalt Driveway Be? Asphalt driveway thickness depends on the soil thatâs being paved on and the industry standards of the region you live in. What is the soil like in the region you live in? Here in Denver Colorado, we have two types of soils we pave on. The first, on the front range, the soils tend to be expansive soils so most contractors excavate and install 3â³ to 6â³ inches of road base and then install 3â of compacted hot asphalt. All of this work is done in a 1 to 2 day period.
