Compact the gravel in 8 - 10 inch lifts for a well compacted base that will not settle. After properly preparing the sub-base, the thickness of the concrete driveway can be 5 inches thick for a residential home and 6 - 8 inches thick for a concrete driveway that will be used for business or commercial use.
Once the site is ready, paving with asphalt follows. 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. That is, 1 inch of asphalt pavement is equivalent to 3 inches of aggregate base.. However, an aggregate base still may be required to ensure a solid foundation for construction equipment on weaker subgrades.
