Driveways In many cases a 4-inch thickness may be adequate, but 5 or even 6 inches of full-depth asphalt will assure you of a stronger, stable driveway under a wider range of climate and loads. As an option, some contractors use 6 to 8 inches of compacted aggregate, or gravel, as a base for 3 inches of asphalt pavement. We recommend full-depth asphalt for driveways, says Kent Hansen, NAPA Director of Engineering. We calculate that asphalt can replace aggregate on a ratio of 1:3 in thickness.
