What is the best thickness for an asphalt driveway? 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 under 3 inches of asphalt pavement.
What are 3 types of asphalt? There are three main types of asphalt: Hot Asphalt, MC Cold Mix, and UPM. There are also different varieties of these asphalts for summer and winter use.
Is 2 inches of asphalt enough for a driveway? Residential driveways typically use 2 to 3 inches of asphalt with 3 being suitable for occasional large trucks or heavy equipment. Underneath the asphalt you should have 6 to 8 inches of granular base aggregate. Underneath this you have soil.
Is asphalt cheaper than concrete? The cost of an asphalt driveway is typically cheaper than concrete, costing $2.00 to $4.00 per square foot. Asphalt prices tend to fluctuate with fluctuations in crude oil prices. In contrast, a concrete driveway costs between $4.00 and $6.00 per square foot for a standard installation.
