There are many reasons to install an asphalt parking lot. The sleek blacktop makes any business look professional and sophisticated. It’s also a renewable product, which helps to cut down on the cost when paving a large lot. However, if you are installing this type of lot, it’s important to understand how to take care of it if you hope to get the most out of your investment.

A Guide to Asphalt Parking Lot Longevity

How long should an asphalt parking lot last?

When properly installed and constructed, a well-maintained lot can last 15 to 25 years. However, if not correctly maintained, it can start to deteriorate in as little as five years.

What can damage the pavement?

Asphalt is a very durable material, but over time, the elements can take their toll. A pavement’s biggest weakness is standing water. Moisture can deteriorate the fine aggregates and allow water to seep down to the sub-grade. When this happens, the surface will begin developing cracks.

When the temperature outside drops below freezing, any moisture in the asphalt will freeze and expand those cracks. Also, the asphalt becomes harder and more brittle in the winter months, which can exacerbate this damage and cause potholes.

Your asphalt pavement can also deteriorate if it wasn’t made to handle the daily traffic load. The weight plus UV radiation and any chemicals spilling from vehicles can dissolve the aggregates holding the asphalt together.

How can I maintain it?

About twelve months after installation, have your asphalt parking lot sealed. Sealcoating will prevent moisture penetration and protect against chemical spills and UV radiation. Repeat this maintenance every two to three years.

At least once a week, inspect the lot for new cracks. Quickly catching and filling small cracks is essential to extending the life of the asphalt. Also, regularly clean the lot to remove dirt, sticks, rocks, and other debris that can damage the pavement. Clean and inspect drains and catch basins to ensure proper drainage.

How can I prevent depressions in the pavement?

Your parking lot has a weight limit. Adding signs that notify drivers of this limit will prevent those in large, heavy vehicles from driving across it or leaving them parked on the pavement for long periods.
