Block Cracks: Why Does Your Asphalt Pavement Have Them?

If you do everything you possibly can to keep your asphalt pavement safe and free of defects, but the pavement cracks anyway, talk to an asphalt contractor. You could have block cracks in your pavement. Although block cracks can be bad, you can do something about them. Learn more about block cracks and how you can fix or address them below.

How Do Block Cracks Form in Asphalt?

Block cracks are large, interlocked defects that form on the surface of asphalt pavement. Although most asphalt pavement defects occur from load-related pressure or stress, block cracks tend to develop under different circumstances. Changes in temperature can cause the pavement to shrink, expand, and spall during the year. 

Block cracks can be minor or alarming, depending on their severity. The cracks can develop in some of the pavement, or the defects can affect the entire surface of the pavement. If the cracks open up, they can fill up with dirt, oil, and other debris. Plants and weeds may also grow in the cracks.

The cracks can get worse without immediate intervention. You'll need to act fast if you want to repair your pavement.

How Do You Fix Block Cracks?

Repairing block cracks isn't something homeowners or businesses want to do themselves. The job can require things, steps, or equipment you might not have access to, such as asphalt filler and sealant. You also need to free the cracks of any debris that may reside inside them.

An asphalt contractor can do the jobs above for you. A contractor will determine the type of block cracks you have and take steps to clean, fill, and seal them. An asphalt paver may also need to remove and replace parts of the pavement during the repairs. 

If spalling severely impacted your pavement, you may need to replace it altogether. Your pavement may deteriorate completely if you don't take action now. A contractor will discuss the replacement with you before they move ahead with the project.

Once a paver repairs your pavement, you want to do a couple of things to keep it in good condition. First, contact a paver as soon as you notice block cracks forming in your asphalt. You want to keep the defects from expanding deeper into your pavement. Also, seal your pavement regularly. A contractor may offer to seal your pavement for you.
