Alligator Cracks: Cincinnati's issue with cracks in asphalt driveways

Asphalt Seal Coating in Greater Cincinnati

Alligator asphalt cracks caused by a bad ground base

Have you ever noticed an asphalt surface that looks like it's been attacked by a giant reptile? Those rough, interconnected cracks, resembling an alligator's hide, are aptly named alligator cracks. They're more than just an eyesore; they're a warning sign of trouble beneath the surface.

What Causes Alligator Cracks in Asphalt Driveways?

Alligator cracks are caused by underlying pavement instability. This instability can stem from various factors, including:

• Weak subbase: The layer beneath the asphalt isn't strong enough to support the weight and movement of traffic.

• Improper drainage: Water seeps into the pavement, weakening the base and causing cracks to form.

• Extreme weather: Freezing and thawing cycles can put stress on the asphalt, leading to cracking.

• Age and overuse: Over time, even well-constructed asphalt pavements will start to crack.

Why Repair Alligator Cracks?

Ignoring alligator cracks can lead to bigger problems:

• Potholes: The cracks widen and deepen, eventually breaking apart into potholes, creating safety hazards for vehicles and pedestrians.

• Water infiltration: Cracks allow water to penetrate the pavement, further weakening the base and accelerating deterioration.

• Increased repair costs: Fixing small cracks is much cheaper than patching up large potholes or resurfacing the entire pavement.

Repairing Alligator Cracks: DIY or Pro?

The severity of the cracks and your DIY skills will determine your approach.

DIY Repairs for Mild Cracks:

• Crack filling: Use a flexible crack filler specifically designed for asphalt. Clean the cracks thoroughly and apply the filler according to the manufacturer's instructions.

• Sealcoating: Apply a sealcoat to the entire asphalt surface to protect it from water and further cracking.

Professional Repairs for Severe Cracks:

• Patching: For extensive alligator cracks, professional patching is necessary. This involves cutting out the cracked area, filling it with new asphalt, and compacting it.

• Milling and paving: In severe cases, the entire top layer of asphalt may need to be milled and replaced.

Remember:

• Early intervention is key. The sooner you address alligator cracks, the less likely they are to develop into bigger problems.

• Consult a professional for extensive repairs. DIY repairs may not be effective for severe cracks, and improper patching can worsen the situation.

• Preventative measures can help. Regular maintenance, such as sealcoating, can extend the life of your asphalt pavement and reduce the risk of alligator cracks.

By understanding alligator cracks and taking prompt action, you can keep your asphalt surfaces smooth, safe, and looking their best.

Additional Tips:

• When choosing a crack filler, select one that is flexible and designed to withstand expansion and contraction due to temperature changes.

• Apply crack filler in cool weather, as hot asphalt can make it difficult to work with.

• Allow the crack filler to cure completely before driving or walking on the repaired area.

• If you're unsure about the severity of the cracks, it's always best to consult a professional paving contractor.

With proper care and attention, you can keep your asphalt pavement alligator-crack-free for years to come.
