How to Maintain Your Parking Lot
Wednesday, July 29th, 2009Parking lot maintenance is an important practice to protect the safety of your tenants as well as the longevity of your investment. Potholes, drainage, puddling, prolonged exposure to the sun, oil deposits, wintertime salting, and heavy traffic all can determine how long the asphalt pavement will continue to be structurally sound.
There are ways to be proactive which can reduce the overall cost of maintaining an asphalt parking lot. The first is to be sure the parking lot is constructed properly in the beginning – if the parking lot is to withstand high truck traffic for example it should be built accordingly.
Next, make sure the majority of the water run off drains properly. Standing water in the wintertime can cause problems on lots especially as the freeze thaw cycle occurrs. Water should drain off of the lot or into storm sewer boxes where it is piped away from areas where it can cause problems.
Any pot holes or surface cracks should be filled or repaired in a timely manner to prevent problems from spreading further. Pot holes can be excavated and patched with new asphalt material. Cracks can be filled with rubberized hot crack filler to prevent them from becoming larger.
As asphalt pavement ages, it loses its asphalt content and may require seal coating to prevent oxidation. Seal coating using a coal tar emulsion product mixed with silica is typically sprayed onto the pavement surface to protect and make it appear black again. After seal coat is applied, new line painting must be applied as well and the finished product appears as though the parking lot is “new.”
