Neglecting asphalt maintenance can prematurely destroy your parking lot. A regular preventative maintenance program is a cost effective way to help extend your driveway from 10-15 years.
The constant friction of tires and snow plows wears away the uppermost layer of asphalt. This later has a lot of gummy petroleum material and not as many aggregate rocks. Once it wears away, the erosion of the parking lot or driveway will speed up. A thinner asphalt is even more likely to cracks, buckle, or develop potholes.
Asphalt is designed to resist moisture penetration as it has glue keeping the aggregate material (rocks) together; however, asphalt is not impermeable to water damage. When cold water sinks into or below the asphalt, it will freeze when temperatures drop. Freezing water expands, interfering with the stickiness of the glue. At some point, the water defrosts and shrinks, putting structural strain on the pavement, and the surface turns grey as the binder (black glue) wears away. Once the rocks are exposed, water can now easily permeate the surface and start making it's way through the driveway surface towards the sub-base where it will either drain (if proper thickness) or just pool up and stay underneath the driveway and cause lifting.
Ultraviolet lights rays may also break down the asphalt by loosening the bond between the different components of asphalt, causing the surface to become brittle and break.
A sealer can also resist spills from car oil and other maintenance fluids that you don't want to stain your driveway.
Have a Concrete Driveway?
Whether your driveway is grey concrete, colored concrete or has a stamped pattern, sealing after the concrete has cured and every few years after is recommended as part of the maintenance routine. A sealed concrete driveway will have a rich color and glossy sheen is desired. Sealers are available in many different gloss levels, ranging from no-gloss to high-gloss. A tinted sealer can even be used that will further enhance the color of your driveway. For colored concrete driveways, a sealer will help prevent efflorescence, which is a white powdery residue that can form on the surface. Slip resistant sealers are also available.
Stain protection is another benefit of sealing a concrete driveway. Your driveway will be subjected to many things in the great outdoors that can leave unsightly stains on the surface - leaves, dirt, fertilizer, pet urine, oil, tire tracks and much more. A sealer will keep all of the above from penetrating the surface of the concrete and leaving an unsightly stain.
