Asphalt pavement begins to deteriorate just about as quickly because it is placed. As the pavement is exposed to oxygen, the asphalt binder (tar) hardens. This hardening leads to a brittle surface that at some point cracks. Cracks within the pavement allow oxygen and rainwater to penetrate the pavement, normally into the sub base, weakening it and minimizing the pavement’s strength. Sealcoating protects the surface and fills surface voids, decreasing pavement’s exposure to oxygen and water and extending pavement life.
The sealer provides a protective asphalt sealcoating that prevents water from penetrating by means of the asphalt. Water will soften the base causing larger much more high priced repairs for instance sink holes, depressions and cracks. In colder climates, the water will freeze and expand which will develop pot holes and cracks throughout the asphalt. Sealcoating your parking lot or driveway can save you a significant level of funds by preventing water and ice from penetrating the asphalt surface.
This can be specifically vital on driveways and sealcoating lots where cars are parked or worked on. Oil and gasoline soften asphalt. A professional-grade coal tar sealer contains additives that allow it to resist any such leaks. By filling surface voids, sealcoating also reduces the depth to which oil or gas can penetrate the pavement.
