Get matched with top asphalt driveway pros in Galax, VA

Instead of a set number of types, asphalt comes in variations designed for different needs. Some are categorized by temperature—hot mix, warm mix, and cold mix. Others are sorted by composition, like dense-graded, gap-graded (such as Stone Matrix Asphalt), porous, and mastic asphalt. There are also modified versions with added compounds like polymers, rubber, or emulsions. Instead of focusing on a number, it may be more useful to understand how contractors customize asphalt for durability, climate, and traffic conditions.

An asphalt driveway should be at least 3 inches thick over a compacted gravel base. Areas with poor drainage should have a thicker stone base. To install a new asphalt driveway over an existing driveway, the new asphalt should be at least 2 inches thick and the existing driveway should be in relatively good condition.

To maintain their strength, asphalt driveways and parking lots need to be sealcoated once every two to five years. You may also need to reapply paint striping every few years as it fades to ensure drivers can safely navigate the parking lot.

New asphalt goes through two stages: drying and curing. Drying typically takes 24 to 72 hours, after which the surface is solid enough for light use like walking or careful driving. While you may be able to park on it after 72 hours, the surface is still soft and should be treated gently. Full curing is a much longer process, taking anywhere from 30 days to a full year for the asphalt to reach maximum strength. During this extended curing period, the asphalt is susceptible to damage from heavy vehicles, sharp objects, and high temperatures. Factors like weather, the specific asphalt mix, and application thickness all influence drying and curing times. For the most accurate timeline and to ensure the longevity of your new asphalt, it is always best to consult with your installation contractor for their specific recommendations.
