The Common Reasons Asphalt Cracks
You’ve seen it a hundred times. A parking lot that looks as though it has been neglected for decades, with potholes and cracks everywhere. More than likely these problems began with smaller issues, with something called alligator or spider cracks. A couple of questions come immediately to mind. Why did these cracks form? How do they get repaired? Excellent questions indeed, and both go to the heart of good parking lot maintenance. After all, you certainly don’t want your property to be known for its lack of upkeep. It’s always better to be remembered for a well-maintained building and grounds.
How Cracks Form
In the northeast, including the Baltimore area, weather can be a big factor in the formation of cracks. The relentless heat of the sun and the corrosive effects of moisture create tiny cracks in the asphalt surface. If these aren’t quickly addressed, they grow into larger cracks and imperfections through the following mechanisms:
- Foreign materials such as rocks and other debris, chisel away at the asphalt
- The cycles of freezing and thawing open up bigger cracks
- Plants and tree roots gain a foothold and weaken the asphalt
- Failure to maintain the parking lot results in growing cracks
- Improper installation and maintenance techniques reduce the longevity of an asphalt job
Once the cracks have started, it’s time for some proper maintenance and repair of the surface. This is the only sure way to get the parking lot back to where it should be.
How Cracks Get Fixed
A professional paving company can fix cracks through several measures. If the situation is caught early, sealcoating can put down a protective layer over the surface and make it look like new again. This is a simple, inexpensive fix that should be done every three to five years. More serious problems may require additional work.
