Your once-pristine asphalt driveway may develop cracks and imperfections over time. These fractures are known as alligator or fatigue cracks and are a common but serious problem that can lead to future damage if not fixed. Use this guide to learn more about alligator cracks, asphalt repair, and maintenance tips for your pavement.

What Property Owners Need to Know About Alligator & Fatigue Cracks

What Causes Them?

While it appears on the surfaces of asphalt, fatigue cracking indicates a more serious structural issue. Cracking can be the result of problems with the base layer. For the driveway or roadway to remain intact, the initial layer of asphalt must provide a sturdy foundation. Problems installing other materials, such as the subgrade, can also lead to crack formation. 

Drainage problems are another common cause of alligator cracks. Water that becomes trapped in asphalt will freeze and expand as temperatures decline in winter. As this occurs, cracks and weaknesses can develop, rendering the ground unstable. They often first appear along a wheel path from the stress and force of a vehicle. 

What Are the Prevention Methods?

Sealcoating is a beneficial method for preventing alligator cracks, as it can keep water from penetrating asphalt in the first place. It’s usually performed after the pavement has been installed, but it’s recommended to re-seal every few years for maximum protection. However, once imperfections appear, asphalt crack filler should be applied to stop the spread.

You should also be careful about the stress you put on your driveway or roadway. Habitually parking your car in the same spot can weaken the asphalt, causing it to crack. Too much weight from heavy-duty work vehicles can also increase its wear and tear. Ask your contractor to install a second base layer to increase the support of your driveway.
