Potholes vs. Alligator Cracking: What’s the Difference?

What Are Potholes?

Potholes are depressions or holes in the pavement that occur when water infiltrates cracks in the asphalt. Over time, the combination of moisture, freezing and thawing cycles, and the pressure from vehicles weakens the asphalt and underlying layers. This causes the pavement to break apart, forming a noticeable cavity.

Asphalt potholes can vary in size and depth, and they’re more than just an eyesore—they can be a serious hazard to vehicles and pedestrians. If left unrepaired, they can grow quickly and lead to larger structural issues throughout your asphalt surface.

For this reason, we recommend that you schedule asphalt pothole repair with us as soon as possible.

What Is Alligator Cracking?

Alligator cracking, also known as fatigue cracking, looks like a series of interconnected cracks resembling the scales of an alligator’s skin. This type of damage is usually caused by repeated traffic loading over a weakened base or subbase. It can also be the result of inadequate pavement thickness or poor drainage.

Unlike a single pothole, alligator cracking often affects a larger area and signals that the structural integrity of the asphalt has been compromised. While it might start with small cracks, the damage can spread quickly, leading to crumbling sections of pavement if not addressed promptly.

Key Differences Between the Two

• Appearance: Potholes are isolated, bowl-shaped depressions. Alligator cracking looks like a web or net of small cracks.

• Cause: Potholes are typically caused by water infiltration and freeze-thaw cycles. Alligator cracking is related to structural failure from stress and fatigue.

• Severity: Alligator cracking often precedes potholes, as the weakened pavement eventually breaks apart. However, both are serious issues that require timely repair.

• Repair Methods: Potholes can often be patched with hot or cold mix asphalt, especially in isolated cases. Alligator cracking may require more extensive repair, such as removing and replacing the affected pavement layers.

Why Early Intervention Matters

Both potholes and alligator cracking worsen over time. That’s why early detection and repair are critical. If you notice signs of either, it’s important to schedule an asphalt inspection as soon as possible. Quick action can prevent the need for costly, large-scale repairs later on.
