Why Asphalt Cracks Form and How to Avoid Them


Asphalt roads and parking lots are known for their durability, but even the best-laid asphalt can fall prey to cracks over time. Cracks in asphalt can be frustrating and unsightly, and they can also be dangerous for drivers and pedestrians alike. Given that many businesses and households in Lake County, FL, rely on asphalt for their driveways and parking lots, it's important to understand what causes asphalt cracks and how to prevent them. This blog will delve into the main causes of asphalt cracks and share some tips on how to avoid them.


1. Heavy traffic and weight loads

One of the most common reasons that asphalt cracks form is due to the pressure of heavy vehicles and equipment. Over time, repeated weight loads, such as those from delivery trucks or construction equipment, can cause cracks to form. When large vehicles park or move around on an asphalt lot, they can also put considerable pressure on the asphalt surface. If you need to support heavy vehicles or equipment regularly, it's important to choose a thicker, more sturdy mix of asphalt that can resist damage.

2. Weather conditions

Changes in temperature and precipitation levels can also cause pavement to crack. In hot weather, the asphalt expands, while cold temperatures cause it to contract. In areas with extreme temperature changes, such as Lake County, FL, asphalt is more susceptible to cracking. Water can also penetrate cracks in the pavement and cause further damage, especially during periods of heavy rainfall. To prevent these types of cracks, you can consider adding a sealant or coating to your asphalt.

3. Improper installation

If the asphalt was not installed correctly or was installed with sub-quality materials, it can experience premature cracking. One of the most common installation errors is laying the asphalt mixture too thin or too thick, which can lead to unstable surfaces and cracks. Hiring a professional asphalt contractor with experience and expertise is a good way to avoid such mistakes. They will ensure the proper and adequate mix of materials to avoid any early cracks.

4. Poor Maintenance

A well-maintained parking lot or driveway can last for many years, but neglecting its upkeep can accelerate the appearance of cracks. Regular seal coating & crack sealing can reduce the frequency & speed at which cracks appear. Promptly repairing any cracks or potholes as soon as they appear is important for extending the life of the asphalt surface.

5. Tree Roots

It's common to see tree roots breaking up concrete sidewalks, but tree roots can just as well damage asphalt. Trees planted near a parking lot can cause problems when the roots grow into and under the paved surface, causing it to crack from beneath. To avoid this situation, either relocate the trees or build a root barrier around them.



While it's impossible to prevent all types of cracks from forming on an asphalt surface, knowing the causes of and prevention methods for asphalt cracks can go a long way in extending the life and function of your surface.
