Properly designed and constructed asphalt pavements rarely wear out from the traffic. Surface deterioration is primarily caused by weathering, oxidation and the destructive softening effects of gas, oil, and de-icers !
The asphalt institute confirms that air, sunlight, and moisture are the major causes of surface deterioration. Unprotected surfaces oxidize and allow the aggregate in the asphalt mix to wash away. Unprotected pavements lose flexibility; aggregate ravels the surface, and pavement becomes rough. The surface becomes brittle and cracks develop.
Water penetrates the cracks and damage progresses. Hydraulic pressure
(expansion and contraction) enlarges cracks during the freeze-thaw cycles.
Cracks allow water to penetrate the sub-surface and rupture the pavement, causing small surface cracks to enlarge until the pavement separates.
The unprotected surface oxides (bleaches out) while gas and oil drippings soften the asphalt surface and cause pavement failure. These petroleum stained areas give the parking lot a dirty, uncared-for appearance. Our sealer is specifically formulated from coal tar base to shield against drying action of the sun to prevent water penetration and resist damage caused by gas and oil. Coal tar bonds firmly to the surface to provide an even-textured durable coating. Coal tar will extend the life of your asphalt pavement and restore that new slate black look at minimum cost ......
