What Causes Driveways to Crack?

A severely cracked asphalt surface.

You walk out of your home one morning and go down to the driveway’s edge to pick up the morning paper. The sun is shining, the birds are chirping, your coffee is hot, and life is good. As you reach down to get the paper, that’s when you notice the dreaded cracks in your driveway. Cracks lead to potholes, and potholes lead to busted tires and a bad time for everyone. 

At one point or another, every homeowner has to deal with cracks in their driveways. Cracks form, tires can potentially be damaged, and you have to call in the asphalt driveway crack repair specialists in the Montgomery County, PA area, Superior Seal Coating. But how and why does your driveway crack and get to this point? 

Natural Winter Causes

All asphalt is susceptible to cracks forming through changes in moisture retention and temperature changes. After heavy snow or rainfall, the moisture will seep through the surface and into the area below. Changes in temperature then cause the moisture to expand and cause cracks to form in asphalt. More often than not, the winter’s cycle of freezing and thawing generates the most cracks, but your driveway, parking lot, or other surface can still fall victim to asphalt cracking throughout the year. 

Here Comes the Sun

While the cold winter months can cause a high volume of asphalt cracking, the other end of the spectrum can be just as hazardous. Extreme heat can cause the asphalt to expand, with the pressure causing cracks to form. If left untreated, these cracks can balloon into larger problems. 

Ground Shifting

Another common cause of asphalt cracking stems from the earth shifting beneath your asphalt. Most asphalt driveways are laid atop a layer of gravel. Throughout the driveway’s lifetime, either through the natural movement of the earth or more extreme reasons (such as heavy storms), the gravel will shift and cause cracks to form as everything begins to settle. 

The Asphalt’s Age

The older your asphalt is, the more likely it is to develop cracks. As it gets further along, the material begins to degrade and loses its natural ability to withstand your surface’s daily pressures. 

What You Can Do

While it appears that there is little you can do to combat crack formation, there are still steps you can take to keep your driveway looking its best. Having a regular maintenance routine in place is essential to keep the cracks from spreading. For the cracks that become too much for you to handle on your own, calling in Superior Seal Coating to assess and address the issue is your best course of action.
