A network of pavement cracks filled with dirt and autumn leaves remains, which resemble the shape of a stained glass. It divides the asphalt into several tiles with irregular shapes while maintaining the fine rocky texture.

We know that over time, asphalt is bound to break down, which is why we offer a variety of services to help keep it strong. Here are some causes of parking lot breakdowns:

A Few Types of Cracks:

  • Fatigue cracking – If your parking lot or roadway has a weakened base due to overloading, wet/soft subgrade, or improper asphalt thickness, this type of cracking can occur.
  • Block cracking – These larger, rectangular cracks result from temperature fluctuations that cause the asphalt to shrink and expand.
  • Edge cracking – If the edges of pavement do not have sufficient support, long cracks along the outer edge can form.

Weather

Weather plays a large role in the breakdown of asphalt. Over time, UV rays continuously penetrate the binder that holds asphalt materials (rock, sand, and aggregates) together. As this happens, it breaks down the binder and in turn, causes the asphalt to decompose. In addition to UV rays, the freeze-thaw cycle of water can play a part in asphalt breakdown. When water seeps into asphalt cracks and freezes, it expands, making the crack larger. When the temperatures warm, it thaws and the process starts all over again, making cracks worse and eventually creating more serious issues.

Heavy Weight

Is your parking lot a commercial parking lot or frequented by heavy trucks, vehicles, or machinery? If so, the weight can be a problem. When heavy weight is applied to asphalt over and over again, it will eventually begin to break it down. Once a problem area (such as cracks or divots) is present, any additional heavy weight will just make it worse.

Neglect

Just like any other structural entity, parking lots need to be maintained; reputable asphalt companies know that maintenance is the key to a strong, durable parking lot. If you find your parking lot has suffered damage, we can offer patching services or resurfacing services to restore it back to its original state. In addition to structural maintenance, we also recommend sealcoating your parking lot every 2-3 years to give it an added layer of protection against natural elements. If you don’t maintain your parking lot, you could end up letting small problems turn into larger problems and in return, face higher costs and lengthier times to fix them.
