ASPHALT PAVEMENT MAINTENANCE

Asphalt pavements have many benefits such as being long lasting, cheap, sturdy, and is used in many different applications. All over the country asphalt is used for parking lots because it is able to withstand heavier loads and can last for a long period of time when proper asphalt maintenance occurs.

If you want to extend the length of time your asphalt parking lasts, developing a plan of management for the asphalt parking lot is a good idea. This involves routine inspections and a continuation of preventive maintenance measures. These are some common procedures for parking lot asphalt maintenance.

Patching is commonly used for repairing areas of pavement that have potholes. Water going into unsealed or improperly sealed cracks in the pavement is the cause of potholes. The crack expands and grows larger when water freezes. A void remains after the ice under the pavement melts. The pavement around the void falls in and becomes a pothole.

Resurfacing asphalt, also known as overlay is a long-term and cheaper solution in a severe case of asphalt damage. If standing water on the pavement know as grade depressions, and/or large areas that are alligatored (connected cracks forming blocks which look like alligator skin), are appearance, then you should consider having your pavement resurfaced.

Infrared asphalt repair is an effective solution for critical repairs is Infrared Asphalt technology. This is a different kind of method which blends a hot-mix asphalt in with the original. Then the area is compacted in a seamless restoration. You should consider infrared repair if you see potholes, pavement heaving, uneven surfaces which surround catch basins (usually occurring after a couple of freeze-thaw cycles), or finally rough area in drives lanes and parking stalls.

Besides routine inspections and continued maintenance, seal coating asphalt pavement with a tar or asphalt based emulsion can slow down pavement deterioration. This is most effective when the seal coat is applied exactly 12 months after the first application and then regularly from between 24 to 48 months after that.
