Repairing Alligator Cracks in Asphalt Driveway

Asphalt alligator cracks are a common problem that many property owners face. Alligator cracks, also known as fatigue cracks, occur when interconnected cracks form a pattern resembling alligator skin on the surface of the asphalt. These cracks are often caused by heavy traffic, poor drainage, and subpar asphalt installation.

If not addressed promptly, alligator cracks can lead to more extensive and costly damage to your asphalt surface. However, with proper repair techniques, you can maintain the integrity of your asphalt surface and avoid further damage. This article will explore the causes, types, and repair methods for alligator cracks.

Causes of Alligator Cracks

Alligator cracks can result from several factors, including:

Heavy traffic: The weight of heavy vehicles, such as trucks and buses, puts excessive pressure on the asphalt surface, causing cracks to form.

Poor drainage: Water accumulation on the asphalt surface can weaken the asphalt’s bond with the underlying layers, leading to cracking.

Inadequate base preparation: The base layer provides support for the asphalt surface. Poorly prepared bases can cause alligator cracks to form.

Subpar asphalt installation: It can lead to early cracking and damage if not installed correctly.

Types of Alligator Cracks

Alligator cracks fall into two categories:

Surface fatigue: This type of crack typically affects the uppermost layer of the asphalt surface and is often caused by heavy traffic. The cracks are usually shallow and can be repaired with a simple sealcoat.

Structural fatigue: This type of crack is more severe and affects multiple layers of the asphalt surface, from the base layer to the surface layer. It requires more extensive repairs, such as patching or overlaying.

Repair Methods for Alligator Cracks

When it comes to repairing alligator cracks, the severity of the cracks will determine the best solution. Here are some of the methods contractors use to repair alligator cracks:

Crack sealing

Minor alligator cracks can be repaired using crack sealing. This method involves filling the cracks with a hot-poured rubberized sealant that will expand and contract with the asphalt. The sealant will prevent water from penetrating the asphalt surface and causing further damage. Crack sealing is ideal for surface fatigue cracks.

Crack filling

Crack filling is another method used to repair minor alligator cracks. This method involves filling the cracks with a self-leveling sealant, which is more flexible than crack sealing and can prevent water infiltration. Crack filling is suitable for both surface and structural fatigue cracks.


For more severe alligator cracks, patching may be required. This method involves repairing the damaged area by removing the existing asphalt, preparing the base layer, and replacing the damaged asphalt with new asphalt. Patching is effective for structural fatigue cracks.


If the damage is too extensive for patching, overlaying the existing asphalt may be the best solution. Overlaying can recover the structural integrity of the asphalt surface and enhance its longevity. This method involves placing a layer of new asphalt over the existing asphalt surface.

As a property owner, you must take immediate action if you observe any alligator cracking on your asphalt surface. Alligator cracks can be frustrating and costly if left unchecked. Hiring a professional paving contractor is the best course of action to ensure the repairs are carried out correctly and efficiently. Whether it’s crack sealing, filling, patching, or overlaying, a qualified contractor will provide a tailored solution that fits your needs. With proper repairs, you can extend the life of your asphalt surface and prevent further damage.
