Asphalt is incredibly durable, especially with proper sealing, but it’s not indestructible. Over time, the pavement may warp, decay, or crack. If you know what kind of damage you’re dealing with, though, you can repair it promptly. Here are a few of the most common asphalt cracks—and the best way to address each one.

3 Types of Asphalt Cracks

1. Alligator Cracks

Thin cracks that branch out across the pavement and resembles reptile scales are known as alligator cracks. These are the most common asphalt crack. Flooding water damages the pavement’s underlying layers, threatening its structural integrity. This flaw happens due to poor drainage, like uneven surfaces that attract pooling water, or repeated freezes and thaws over a short period. Because alligator cracks are indicative of a structural problem, you must remove and replace the affected area; however, patching serves as a temporary solution. 

2. Linear Cracks

As the name implies, linear cracks are long vertical lines that run up the pavement. They develop because of wear and tear, although bad joint construction could also be to blame. Depending on the size of the crack, patching may be an adequate way to repair it. However, you should repair pavement with several linear cracks that are especially deep or wide—but not before determining why it was vulnerable to such damage in the first place.

3. Block Cracks

Block cracks refer to large rectangular cracks. These develop when the asphalt cannot expand and contract with the changing temperatures. If the cracks are less than one-half inch deep, sealing the surface will provide a quick fix by keeping moisture out. If they're deeper, though, you should schedule asphalt repair. The technician will recommend removing the affected layers and applying an overlay.
