Alligator cracking Alligator cracking is a network of interconnected cracks that resembles the pattern of an alligator's skin. It commonly indicates that the pavement has experienced structural distress.
Although most often associated with asphalt pavement, alligator cracking signals that the pavement structure has weakened and can no longer adequately support applied loads. The condition may result from repeated traffic, inadequate foundation support, or long-term deterioration. Localized patching alone is often insufficient if the underlying structural problem remains.
Frequently Asked Questions About Alligator cracking
What is alligator cracking?
A network of interconnected cracks resembling alligator skin, indicating the pavement structure has weakened.
What does it tell you?
That the pavement can no longer support the loads applied to it, usually because of foundation failure rather than a surface problem.
Is it common on sidewalks?
It is most associated with asphalt pavement, but the same pattern signals structural distress wherever it appears.
Can it be patched?
Localized patching rarely lasts, because the underlying structural weakness remains. Reconstruction of the affected area is usually needed.
