Asphalt deterioration is affected by many contributing factors, some of which are listed below:

  • WATER . . WATER . . WATER . . – are 3 elements that destroy pavement by getting into cracks in the surface or after oxidation has set in. Once water gets into the surface, nature, through its freezing and thawing process causes more cracks and enlarges the existing cracks.
  • Original construction quality – which can lead to deterioration in several ways.
  • Oxidation – As stated in another question is this section pertaining to maintenance costs, even on the most sound sub base and overly construction, oxidation is a natural occurrence that can only be controlled with sealcoating using a good Cold Tar Emulsion sealer like Nyra.
  • Dumpster Trucks destroy Asphalt especially in the area where the trucks lift the dumpsters. The rocking motion creates stress that few asphalt pavements are designed to with stand.
  • Cracks. Asphalt is a flexible pavement and cracks are a natural part of the aging process. When left unfilled, these cracks will allow water penetration into the sub base which will prematurely cause potholes and other types of extensive pavement failure.
  • Petroleum spills, since asphalt is an oil based material, any oil based product that is spilled upon it will dissolve the cement that bonds the asphalt together and cause premature failures.
  • Heavy loads placed upon pavement i.e. a fully loaded tractor trailer.
