Asphalt pavement is mostly rock and/or stone and gravel, along with a binder. The rock, or aggregate, is held together with this binder known as asphalt cement. Maintaining this binder is essential to preserve the service life of asphalt surfaces. Rain, U.V. rays, and chemicals, as they are introduced into the asphalt, will degrade the binder and thus begin the degradation process of the asphalt. This will continue and create a surface that turns brittle. So, the purpose of asphalt sealcoating is to protect the asphalt pavement and to beautify at the same time. The earlier an asphalt sealer can be applied in the life cycle of asphalt the better.
To reduce the effects of the above-mentioned elements, it is important to implement a maintenance program that utilizes sealcoating to extend the life of your parking lot or driveway. Sealcoating will provide a layer of protection blocking out harmful intrusions such as water, oils, and U.V. damage. In addition, when asphalt sealer is applied to manufacturers’ specifications, sealcoating provides a slip-resistant surface with a deep black finish that beautifies the parking lot or driveway. Asphalt sealers are typically bituminous based products or acrylics. The sealcoat is in a liquid formulation of one of the above emulsions, mixed with water, silica sand, polymer additives, and other proprietary fillers and solids. These products can be applied by brush, spray or squeegee.A regularly scheduled sealcoating program will more than double the life of the asphalt, saving you significant dollars down the line.
Instead of having to pay thousands of dollars for new pavement, it is more cost effective to spend only pennies on the dollar per square foot to maintain.
