Sealcoating or Repaving are general terms used to describe the application of a top or protective coating material on an existing road pavement. Asphalt consists of rocks, sand, gravel, and the binder that would keep them all together. The binder is a by-product of the distillation process of certain types of crude oil. Aging asphalt will eventually break down, losing its ability to bind or stick together in the process.

Normal everyday use in addition to harsh weather conditions can eventually loosen the top layer of asphalt leading to erosion. This can result in moisture penetrating the asphalt, and slowly breaking up the surface. Maintaining this binder is paramount in pavement maintenance. As one would expect, without it, the asphalt will begin to break down. The most common causes of binder degradation are rain, ultraviolet rays from the sun, and chemicals such as antifreeze and car oil.

Asphalt cracks don’t look good and can get expensive, in no time. You may only notice small defects at first, but these will eventually form into cracks. You have to take action and fix them as soon as they occur. Cracks allow ice and water to penetrate your driveway which in time will break up the asphalt. Sealing asphalt cracks is the most economical way to prevent asphalt degeneration and expenses in the future.

There are different things that can make your asphalt to crack. To name a few:

  • Poor Foundation
  • Earth movement
  • Heavy vehicles
  • Roots from trees

These cracks in your driveway or parking lot can compromise the integrity of your asphalt, and this is why you should seal coat or repave your asphalt driveway. Do you need more reasons why you should seal coat or repave your asphalt driveway? Here they are;

Jet Black Finish

Driveway sealing restores that bright black look to your driveway. This is the first part of your property a potential customer or visitor will see.

Sun and Oxidation

Sealcoating is UV ray resistant, and it prevents oxidation. Oxidized pavement can benefit from seal coating as the sealer reinstills binder into the pavement helping to prevent damage. Asphalt pavement starts to degenerate as soon as it set. When the pavement is exposed to oxygen, the binder(tar) is hardened. The hardening resulting in some fragile area will eventually crack. The cracks on the pavement allow oxygen and rainwater to enter the pavement, most often into the subgrade, weakening and reducing the strength of the pavement. Sealcoating or repaving protects the surface and fills the voids, reducing the exposure of the pavement to oxygen and water, thereby prolonging the life of the pavement.

 

Water and Ice

Sealcoating a driveway makes it resistant to water and ice. The seal provides a protective cover that prevents water penetration through the asphalt. When water softens the base, it results in the need for great and expensive repairs such as sink holes, depression, and cracks. In cold climates, the water will freeze and expand which will create holes and cracks throughout the asphalt. Repaving your parking lot will save you a significant amount of money by stopping water and ice from penetrating the surface of the asphalt.

 

Oil & Gas Spills

Sealcoating and repaving are resistant to oil and gas spills. Asphalt sealing helps to resists damage to your asphalt caused by gasoline, oil, sand, salt and many other chemicals. This is particularly important in driveways and parking areas where the cars are parked on. Oil and gas soften asphalt. A coal tar seal coating contains additives that allow it to withstand such leaks. The depth to which oil or gas can penetrate your pavement is greatly reduced by seal coating and repaving.

Weatherproof

Sealcoat is specially formulated to help protect your driveway from the damaging effects caused by weather conditions. Also, Sealcoat helps the pavement to resist against the discoloring and drying effect of sunlight.

 

Reduce Maintenance

Sealcoating is a preventative maintenance and depending on asphalt usage is required every few years. Keeping your driveway maintained frequently will help prevent costlier damage.

 

Preserve Your Investment
