When it comes to deciding which are your best options for a new home driveway, we recommend going with a Full Depth Asphalt Driveway. Full Depth Asphalt will provide the homeowner with the best combination of strength, flexibility and durability, especially in climates that have fluctuating temperatures throughout the year.
Starting with a good topsoil is paramount to the building of a solid asphalt driveway. In near perfect soil conditions a 4 inch thickness may be adequate but a 5-6 inch aggregate will provide a stronger, solid driveway for heavier loads. If we find that the subgrade quality is unstable we may recommend as much as 6 inches of crushed aggregate be laid and thoroughly compacted first. In some soil cases, 6-8 inches of compacted aggregate or gravel will be used for the base.
"We recommend full-depth asphalt for driveways," says Kent Hansen, former NAPA Director of Engineering. "We calculate that asphalt can replace aggregate on a ratio of 1:3 in thickness. ie. 1 inch of asphalt pavement is equivalent to 3 inches of aggregate base."
