Imagine the back of an alligator with all of its scales and ridges. This is what an asphalt driveway or parking lot looks like when there is damage to the sub-base. Known as alligator cracks, asphalt service technicians say the condition not only causes dangerous buckling but also leads to vehicle damage and physical injuries for pedestrians. The encouraging news is there are ways to avoid these structural imperfections. Here are several.

How to Avoid Asphalt Alligator Cracks 

1. Ensure Proper Sub-Base Installation

One of the best ways to prevent alligator cracks is to ensure the sub-base is installed by a professional. These layers of aggregate material are critical for supporting asphalt driveways and parking lots. A licensed and experienced asphalt services technician will determine the proper base thickness, stability, and compaction levels to endure winter freezes, thaws, and vehicle traffic. 

2. Fill in Cracks

If you notice small cracks forming in your driveway, parking lot, or other asphalt surface, have them filled in. They are designed to offer temporary support to keep larger alligator cracks from forming. Determining why the cracks have emerged is essential for obtaining the necessary repairs. 

3. Apply Periodic Seal Coatings

Seal coating provides a barrier against the sun’s ultraviolet rays, which can trigger alligator cracks. The application is also effective for preventing cracks and potholes and creates a durable safeguard so that rain, frost, and snow don’t penetrate the asphalt sub-base. Seal coating should be done two years after an initial asphalt surface installation and every few years afterward. 

4. Repair Potholes

Over time, potholes may appear on your asphalt surface due to weather exposure, heavy vehicle traffic, and improper installations. Potholes should be repaired right away to prevent them from spreading and causing alligator cracks. These dangerous fissures must be filled and safely leveled to ensure the longevity of the repair.
