Apply a seal coat within six months to one year of installation of new asphalt. Check for cracks and have them filled annually. Any crack, which is ¼-inch or wider in the pavement, will allow moisture to penetrate to the subbase. The goal of a good pavement management plan should be to keep the moisture from entering the asphalt pavement. Additionally, we recommend applying sealant every two- to-three years, depending on wear. This will help prevent deterioration of your pavement due to the sun’s rays, gasoline, traffic, and the weather elements.
