Pavement maintenance plans can vary in scope, but they never vary in purpose: 
      to increase pavement life.

      A pavement maintenance plan usually includes crackfilling, pothole repair, and 
      sealcoating.  Sealcoating is one of the most important elements of a pavement  
      maintenance plan because it slows pavement deterioration. 

      However, a seal coat, like all pavement maintenance repairs, is a temporary 
      means of inhibiting pavement deterioration and needs to be applied on a 
      regular basis, about every 2 years.

    What are the benefits of sealcoating? 

   Beautification.  Fresh sealcoat adds color to a pavement, enhancing its 
   appearance and making it look like new.  A just sealed pavement has a 
   clean, rich look that presents a positive image of the company, facility, 
   or residential complex.

   Slows oxidation and water penetration. Exposure to oxygen hardens 
   asphalt binders and results in a brittle pavement surface that soon cracks.  
   These cracks permit water to penetrate the sub-base, weakening it and 
   reducing pavement strength.  Sealcoating fills surface voids, reducing 
   exposure to oxygen and water, prolongs pavement life.

   Resists gas and oil spills.  Gasoline dripping from a fuel tank during 
   hot weather or oil leaking from the engine can soften asphalt pavements. 
   Because coal tars aren't soluble in gas or oil, coal tar sealers prevent 
   damage caused by spills.   Manufacturers of asphalt emulsion sealers 
   usually add polymers to increase resistance to gas and oil.  By filling 
   surface voids, sealing also reduces the depth to which oil or gas can
   penetrate the pavement.

   Resists ultraviolet rays.  Ultraviolet rays from the sun break the links 
   between carbon bonds within asphalt, but these rays don't damage the 
   aggregate within asphalt concrete.  Although the seal coat does not repair 
   any damage that has already occurred to the asphalt, it does prevent 
   ultraviolet rays from further damaging the asphalt pavement.

   Easier to clean and maintain.  Sealcoating fills surface voids while 
   coating the pavement surface.  The resulting smooth and even texture 
   makes surface easier to maintain year round.

   Promotes increased pavement flexibility.  A seal coat keeps a parking 
   lot black.  The blacker it is, the more heat it draws from the sun; the more 
   heat it draws, the more pliable it is; the more pliable it is, the more able it 
   is to withstand traffic volume changes without cracking.

   Cost-effective in the long run.  The price of asphalt concrete will always
   be affected by crude oil prices, which fluctuate when supplies vary.  It is 
   less expensive to seal coat a parking lot every few years than it is to 
   overlay or place a new lot.
