Asphalt surfaces handle auto traffic and stress day in and out. “Alligator” cracks, a form of fatigue, develop when they’re neglected. They’ll only spread and worsen over time, which is why you should address them right away. Here’s a closer look at why these cracks occur and how to prevent future problems after they’re repaired.

What Are Alligator Cracks?

These cracks get their name from their resemblance to alligator skin. The issue develops when longer cracks spread across an asphalt surface. The interconnected cracks are usually no more than 6 inches across and will gradually weaken the asphalt and create potholes.

These can trip pedestrians and create a loose, dangerous surface for vehicles. They’re also unsightly and negatively impact curb appeal.

What Causes Them?

Many cracks occur because too much weight is placed on the surface, as cracks only worsen under repeated stress. Water also leaks in and erodes the asphalt sub-layer.

As poor-draining surfaces are weakened by standing water, cracks form. These usually begin at the bottom of a surface and work their way upward, but they can also form on the edges and spread downward.

How Are They Repaired & Prevented?

Repair cracks as soon as possible. Paving professionals will resolve smaller cracks with an aggregate filler. They’ll then sealcoat the surface to prevent further moisture damage. A contractor may dig into the alligator cracks to see if the sub-layer is eroded. If so, they’ll remove the damaged asphalt, fill the pothole, and smooth it to create a strong, even surface.

Future cracks can be prevented by a deep layer of asphalt that supports passing traffic and heavy vehicles. Make sure it’s sloped to guide rainwater to a drain. Hire professionals to seal the surface every three years to prevent moisture erosion.
