4 FAQ About the Life Expectancy of Asphalt Parking Lots, Shelbyville, Kentucky

If you’re a business or property owner, the quality of your asphalt parking lot is a reflection on your commitment to the safety of your customers and the quality of your work environment. Potholes, cracks, and loose asphalt can be hazardous for drivers, pedestrians, and the disabled or elderly. Here are some answers to common questions about how long your asphalt lot should last and how you can help to extend its life.

4 FAQ About Asphalt Lots

1. How long should an asphalt lot last?

A well-constructed asphalt lot should last about 25 years—if you care for it well and perform regular maintenance. In high-traffic commercial lots or roadways, the life span may only be 15 years, especially if heavy trucks frequent the area. Whether a lot is newly constructed or overlaid onto an old one can also affect life expectancy. An overlay on a damaged lot will not last as long as a freshly laid asphalt one.

2. What can I do to keep my lot safe and extend its life?

asphaltRegular maintenance is one of the best ways to get the most life from your asphalt. Have a sealcoat applied every few years or when you can see bare pavement beneath the coating. Fill cracks as they appear to prevent water from getting in. When water freezes, it will expand and create larger cracks. It can also cause the pavement to dip or buckle when water collects underneath. Proper drainage will direct it away from the lot and mitigate possible damage.  

3. How does climate affect asphalt?

Asphalt is strong, but it’s not impervious to temperature changes. While freezing weather can cause ice to expand cracks, a hot climate can be just as tough on asphalt. High heat can damage the layers below the surface and allow air gaps to form. Over time, the weight of vehicles on the weakened asphalt can cause it to crumble, allowing potholes to form.

4. When should I repair or repave asphalt?

If your asphalt is approaching 20 years, it’s time to replace it. This is more cost effective in the long term over continuing to repair an aging lot. If your asphalt is less than 15 years old and the surface is still relatively even, you can continue to repair and seal for a while longer.
