Asphalt is one of the most popular paving materials due to its affordability, clean appearance, and resistance to the elements and wear. However, it’s not uncommon to detect cracks forming in asphalt driveways or parking lots after a few years. While it may not be clear why cracking has occurred, determining the most likely cause is a vital step in the repair process. Take a look at a few common types of asphalt cracks and what you can do to repair them in the article below.

What Are Some Common Types of Asphalt Cracks?

1. Alligator Cracks

So-called because they resemble the scales on an alligator’s skin, alligator cracks are the most common and serious form of asphalt cracks. Usually, they form when moisture penetrates the foundation below an asphalt driveway or parking lot, thus causing the surface to destabilize and fragment.

It’s possible to carry out short-term repairs to resolve this issue, but patching and resealing won’t completely restore the pavement, since the underlying structure is compromised. You can avoid the need to repave completely by resealing your asphalt every three years and patching any small cracks as soon as they appear to keep moisture out.

2. Block Cracks

Block cracks get their name because they form large rectangular chunks in paved surfaces. This typically occurs when asphalt can’t expand and contract with rising and falling temperatures as the seasons change. As long as block cracks are less than an inch deep, they can be patched. However, if they go deeper, it might be necessary to remove the uppermost layer and resurface the pavement.

3. Edge Cracks

Edge cracks form along the boundaries of paved surfaces, usually due to insufficient structural support around the edges of a parking lot or driveway caused by soil erosion or settlement. If detected early enough, it may be possible to save the pavement by reinforcing the soil under the edges, patching the cracks, and clearing roots and other obstructions which may impede proper drainage.
