What Causes Asphalt Cracks and How Should They Be Repaired?

Asphalt cracks are often the first visible sign that water, traffic, age, or movement is stressing the pavement. The right repair depends on the crack pattern and the condition beneath it. Treating cracks early is usually simpler than waiting for moisture to weaken the base.

Common reasons asphalt cracks

• Water entering joints or low spots
• Base movement or poor drainage
• Repeated vehicle loads and turning
• Surface aging and oxidation
• Edge support loss

Match the repair to the problem

Narrow, stable cracks may be cleaned and sealed to limit water entry. Broken pavement, potholes, or areas with a weak base need more than surface sealant and may require patching. Widespread interconnected cracking can indicate structural distress, making an overlay or reconstruction worth evaluating.
