What Is Alligator Cracking in Asphalt?
Alligator cracking is a network of interconnected cracks that looks like reptile skin. You’ll often see it in drive lanes, parking stalls, and high-traffic areas where asphalt takes repeated stress. Unlike a single surface crack, alligator cracking usually points to a deeper issue beneath the pavement, not just normal aging.
If you’re noticing these patterns on your driveway or parking lot, it’s a strong signal that asphalt repair should happen sooner rather than later.
What Causes Alligator Cracking?
Alligator cracking forms when the pavement structure can’t support the load it’s carrying. Common causes include:
- Weak or failing base: If the foundation under the asphalt is compromised, the surface flexes and breaks.
- Poor drainage: Standing water or water that seeps into the pavement can weaken the base over time.
- Heavy traffic loads: Frequent delivery vehicles, dumpsters, or repeated turning movements accelerate damage.
- Aging asphalt: As pavement oxidizes, it becomes brittle and more likely to crack under pressure.
- Thin asphalt installation: If the asphalt layer isn’t thick enough for the use case, it can fail prematurely.
Can You Patch Alligator Cracking?
Patching can be effective if the damage is localized and the underlying base is still stable. In those cases, a targeted repair removes the failed section and replaces it with new material to restore strength and a smoother surface.
However, if alligator cracking is widespread across a parking lot or driveway, patching often becomes a short-term fix. New patches may hold temporarily, but the surrounding pavement can continue failing.
For localized fixes, see our asphalt repair and patching services.
When Repaving Is the Better Option
Repaving is typically recommended when:
- Cracking covers large areas
- The pavement has visible depressions, soft spots, or uneven sections
- Water is pooling and worsening the problem
- Repairs are frequent but results don’t last
If the base needs correction, repaving gives you a stronger foundation and better long-term performance.
