Asphalt Driveway Maintenance

Nine months to one year after the installation, the driveway will need to be sealed for the first time. Sealing will protect your driveway from the effects of oil, weather, and salt, but it is a coating and as such does not last forever. To maintain the integrity of the driveway, it should be resealed every three to five years after the first sealing. In addition, any cracks that appear in the asphalt must be repaired as quickly as possible. Besides any aesthetic consideration, cracks in the surface, even hairline ones, can admit moisture, which will erode the asphalt surface. This is even more problematic in the winter when the freeze-thaw cycle can cause small cracks to widen and cause damage beneath the surface of the blacktop.
