Among paving materials, asphalt is one of the most widely used and valued for its low cost, durability, and appearance. However, it will experience wear and tear over the years because of exposure to the elements. This prolonged exposure will lead to the formation of multiple cracks resembling the scales on an alligator’s back. “Alligator cracking” has several causes, each requiring a different solution, which you can learn more about in the guide below.

What Causes Alligator Cracking?

Alligator cracking usually results from water seeping into existing small cracks and potholes in a paved surface. The moisture destabilizes the paving foundation, causing it to subside and the surface to weaken and break apart.

This issue can also result from tree and shrub root growth under pavement, soil settlement, moisture-heavy clay soil, and erosion that weakens paving foundations. Pedestrians and vehicles will further accelerate the process, leading to the pavement breaking down into multiple small patches separated by deep cracks.

How to Fix Alligator Cracking

If detected early enough, alligator cracking can be prevented by patching and sealing existing small or transverse—side to side—cracks which might otherwise worsen. It may also help to limit foot and vehicle traffic on damaged pavement.

However, if alligator cracks have already begun to form, patching and resealing will only be a temporary solution, as the pavement will have been critically weakened. In this case, the only viable long-term solution is to remove and repave the affected area on top of a fresh, strong foundation. As long as it’s regularly repaired and resealed every three years, the new pavement should last for up to 20 years.
