How to Prevent and Repair Asphalt Parking Lot Cracks

Asphalt paving is a durable choice for commercial parking lots. Over time, however, cracks can develop due to temperature changes and high volumes of traffic. While it’s possible to prevent cracks to some degree, at a certain point, you may need to have repairs performed. Here’s what you should know about keeping cracks out of your lot for safety and aesthetic reasons. 

Preventing Cracks
One of the most effective ways to protect parking lots against cracks is to have your pavement coated. Sealcoating is a service offered by many asphalt paving companies that adds an extra protective layer on top of the pavement’s surface. This creates an additional line of defense against the agents that could cause cracks, potholes, and other types of damage. For instance, it protects against oxidation, spills from oil and other chemicals, water damage, and UV rays. Most commercial parking lots will need to be sealcoated every two to four years.

Cleaning your lot is also a good way to protect against cracks. Even if small debris may not seem like a big deal, the buildup of detritus like leaves and dirt can cause friction and degrade the material. Finally, try to keep weight evenly distributed on your lot. This may mean repainting the lines to redistribute traffic patterns or parking spots from time to time. 

Repairing Cracks
If you notice a crack in your lot, be sure to contact your asphalt paving contractor promptly. Left unaddressed, water can seep into cracks and then freeze and expand when the temperature drops. This can create deeper cracks and widespread damage. 

Contractors can fill minor cracks with commercial-grade materials to prevent spreading. If cracks are widespread and resemble alligator scales (known as alligator cracking), this could indicate damage to the foundation of the lot, which may require more extensive repairs.
