How can sealcoating extend the life of asphalt?
Sealcoating is not only for aesthetic purposes. Yes, it does give your new surface a rich, black look. It will protect against damage from gas and oil spills. In addition, the natural tars and emulsions in the asphalt can oxidize over the years, drying out the surface and making it more apt to fail. Sealcoating will prevent the oxidation.
