asphalt sealcoating protects from sun damage

Asphalt Sealcoating Protects Parking Lot

Your asphalt surface is very durable and can tolerate pretty high heat. However, that doesn’t mean that it is immune to UV damage. Typically, your asphalt surface will run at least 10 degrees hotter than the temperature outside depending on several variables. They are especially dependent on strength of sun on the given day. Asphalt sealcoating helps to protect your parking lot from damages associated with sun exposure like; decay, cracks, warping and deformities.

asphalt cracking due to dun damage and the benefits of asphalt sealcoatingAs the UV rays from the sun fuses with the oxygen in the air, the chemical bonds that strengthen your asphalt instantly begin to break down. It is important to understand that although it will start almost immediately, it will take time to breakdown. Damages will take time before they are visible. When UV rays begin to breakdown your asphalt, the asphalt surface becomes brittle. This is because the sun is essentially slowly drying out the liquid in the asphalt agent that keeps the aggregate together. This brittleness makes asphalt more susceptible to damages from water and winter’s freeze-thaw cycle.

Major Signs of Asphalt Sun Damage:

  1. Surface Breakdown & Decaying – Sections of asphalt may become loose.
  2. Cracking – The main reasons for cracks in asphalt are from sun, water, and/or shifting. Under high heat, it is also likely that asphalt will swell which can lead to expansion cracks as well.
  3. Warping – Asphalt may begin to spread to the corners of your lot and thin out over time because the tar in the hot asphalt mixture begins to melt when heated to high temperatures.
  4. Melting/Disfigurement – Your asphalt may begin to warp or take on a different shape due to this melting.

It is important to understand that sun damage to your asphalt is inevitable. There is no solution that will completely stop it from happening over time. However, asphalt sealcoating is the most effective way to slow down the process, extending the life of your pavement. Asphalt sealcoating is the process of applying a protective barrier on top of the asphalt to help shield it from the elements and various chemicals it may come in contact with. Your asphalt sealer will help to protect asphalt from water by resisting water seepage to the base of your lot, while also slowing down the oxidation caused from UV rays. Asphalt sealcoating can also help to protect your asphalt surface from damaging spills like car oil that can further break down your asphalt.
