Why Asphalt Deteriorates

 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  ...... Call Today for Your Free Estimate 304-592-3052! ...We are Top Notch :)
