Asphalt Driveway Tips

Count the Cost

• Asphalt is typically sold by the ton, rather than by the square yard like concrete, which requires a bit of mathematical computation to determine how much you need to surface your driveway. One ton of asphalt is equal to the square yards of surface to cover, multiplied by the depth of the asphalt in inches, multiplied by .057. Multiple the number of tons by the current price per ton for asphalt to determine the total cost of your surfacing material. Numerous online asphalt volume calculators are available that can generate the required tonnage by plugging in the length, width and depth of your driveway.

Prepare the Underlying Base

• An asphalt driveway surface is only as good as its underlying base. Crushed rock or gravel is a good choice for the underlying base. The driveway should be excavated deep enough to allow for a 4- to 8-inch layer of base material, depending on the type of soil present. Well drained, sandy loam will not require as thick a base as clay, according to True Value Corporation. Allow the base to sit in place for several days to allow for natural settling, then compact it with a heavy drum roller before laying the asphalt.

Properly Seal the Driveway

• You can walk on new asphalt driveways immediately after they are finished. Don't drive or park vehicles on the new surface for at least three days, according to DrivewayTips.com. Asphalt needs about three months to properly cure before it is sealed. Don't park or drive vehicles that have known fluid leaks on the new asphalt surface until it has been sealed. Asphalt driveways can keep their fresh, new look if they are resealed every two to four years. Asphalt is a flexible material, but some cracks are inevitable. Prevent major problems by filling cracks and holes as soon as they appear.
