How to Treat Alligator Cracks
Alligator cracks are a frequent issue that can appear on asphalt surfaces, often indicating deeper structural problems. They not only affect the appearance of the surface but can also lead to more significant damage if not addressed promptly. Proper treatment is essential to prevent further deterioration and extend the lifespan of the pavement. Let us see what alligator cracks are and how to treat them.
What are Alligator Cracks?
Alligator cracks are a network of interconnected cracks that resemble the rough, scaly pattern of an alligator’s skin. These cracks usually develop due to repeated stress on the asphalt, such as heavy traffic, poor drainage, or an inadequate foundation. Over time, the asphalt weakens, causing the surface to break down into these distinctive patterns. If not treated, alligator cracks can worsen, leading to potholes, further structural damage, and costly repairs.
How to Repair Alligator Cracks?
1. Assess the Damage
Start by evaluating the extent of the cracks. For minor surface-level issues, simple repairs might be enough. However, widespread or severe cracking may require digging deeper to inspect the sub-base and identify underlying problems. A contractor can help determine whether modifications to the sub-base are needed to prevent future damage.
2. Clean the Area
Thoroughly clean the damaged surface by removing dirt, debris, and vegetation. Use a broom or a high-pressure washer to prepare the area for repairs. A clean surface ensures better adhesion of the repair materials.
3. Diagnose the Underlying Problem
To fully understand the extent of the issue, your contractor may need to excavate and assess the asphalt’s sub-base. This step is essential for identifying problems like poor drainage, inadequate compaction, or a weak foundation. Fixing these issues is crucial to avoid recurring damage.
4. Repair Minor Cracks
For small, isolated cracks, use a crack filler or asphalt sealer to close the gaps. This will prevent water from seeping in and causing further damage.
5. Patch Larger Areas
If the damage covers a larger section, the affected asphalt should be removed and replaced. Your contractor can remove only the damaged areas, repair the sub-base, and lay new asphalt. In cases of widespread cracking, replacing the entire surface, along with properly reinforcing the sub-base, may be more cost-effective in the long run than repeatedly addressing smaller issues.



Closing Remarks
Alligator cracks can quickly cause damage to asphalt surfaces, but with the right handling, they can be repaired and prevented from getting worse. By evaluating the extent of the cracks, cleaning the area, addressing any underlying issues, and making the necessary repairs, you can extend the life of your pavement. For more severe cases, replacing damaged sections and reinforcing the base can be a more cost-effective solution in the long term.
