An asphalt driveway or parking lot can last years with proper maintenance. When properly maintained, the life expectancy of your driveway or parking lot can realistically be doubled.
Asphalt is a combination of rock, sand, and glue. The glue is what binds it all together. The glue, over time can weaken as it is exposed to light, chemicals, petroleum products, salt, and extreme weather conditions. Once the glue has failed you will lose the top surface to your asphalt. The most obvious changes that you will notice is the asphalt will eventually change from black, to brown, and finally to gray.
One of the best way to prevent this is to have your asphalt driveway or parking lot seal coated. Seal coating as a preventative maintenance for asphalt driveways and parking areas protects the surface from these harmful elements and prevents the deterioration of the surface. However, it is important to get your surface seal coated before the deterioration has started. If you do not have your asphalt seal coated and allow your asphalt driveway or parking lot to degrade, it will be too late for preventative maintenance.
Seal coating is an easy an inexpensive way to help prevent damage to your asphalt surfaces. Not only does it prevent damage but it also improves the overall appearance of your asphalt driveway, commercial lot, residential roadway, etc. Once applied, your park lot will have a more attractive, deeper black color.
