All asphalt pavement surfaces should be maintained on a routine basis to deal with the daily accumulating stresses of traffic, moisture and oxidation. Sealcoating is a refined coal tar or asphalt surface treatment used to both maintain and extend the life of your pavement surface. Sealcoat treatments (especially coal tar based) enable asphalt surfaces to resist oxidative aging as well as degradation from fuel & oil spills. For newer pavement, sealcoating provides a tremendous value in preventative maintenance. For old and weathered pavements, a newly sealcoated surface provides instant curb appeal and extended life.
