The average lifespan of a commercial parking lot is about 25 years. However, some asphalt parking lots last longer than that, and others have a much shorter lifespan. Learning what factors affect your commercial parking lot can help you determine approximately how long your parking lot will last and when you may need to call in commercial paving services for a new parking lot. 

Weather Conditions 

Weather conditions can greatly affect how long a commercial parking lot will last. Parking lots that are exposed to large amounts of rain or flooding are more likely to crack or crumble. Ice and the salt used to melt that ice can easily damage asphalt and shorten its lifespan. The weather conditions where you live may also shorten the lifespan of your asphalt or help it to last longer. 

The Amount of Traffic That Uses the Parking Lot

The amount of traffic in your parking lot also has an effect on the asphalt. Understandably, the more traffic you have, the shorter your asphalt surface will last. On top of this, if you have heavy vehicles, such as semi-trucks, frequently on the asphalt, the weight of those vehicles can further wear down the surface. 

The Aggregate Mixture of the Asphalt

Asphalt is made up of different aggregate mixes. A commercial paving company will put together a mixture based on the weather in your area when the surface is being laid and the normal weather conditions for the area. The right aggregate mixture helps your asphalt better react to the weather it will be exposed to, while also ensuring it sets and cures in the weather it is installed during. 

The Thickness of the Asphalt Surface

The thickness of asphalt parking lots can vary. There are many factors that go into determining how thick an asphalt surface should be, including the amount of traffic the parking lot will be exposed to and your budget. A commercial paving company can work with you to select the right thickness of the asphalt surface for your needs. 

How Well Maintained the Parking Lot Is

The final factor that affects how long a commercial parking lot will last is how well maintained the parking lot is. Sealcoating the parking lot, sealing cracks, and repairing potholes can all help to extend the life of the asphalt surface. 

Selecting a reputable and knowledgeable commercial paving company can help your commercial parking lot last as long as possible. Contact a commercial paving service for additional information.
