While asphalt paving can last for 25 to 35 years, everyday wear and tear and exposure to the elements will affect its integrity over time.

The first step to proper asphalt paving maintenance is to be aware of the common causes of asphalt damage so you can take preventive measures. Here are three of them.

Tree Roots

Tree roots can grow and spread several feet away from the tree, typically reaching for water sources. If there’s a tree growing near the asphalt pavement, you might end up with a root creating an uneven surface. If the dirt beneath the surface buckles because of root growth, this may cause sections of your driveway or parking lot to collapse.

Solution: You can opt to cut the roots in question from the tree or place a small amount of copper sulfate on the areas around your driveway or parking lot to keep the roots from spreading further. Be careful not to overdo this, though, as this can harm the environment.

Water

Left unaddressed, water can cause major asphalt damage. Water pooling on the pavement and freeze-thaw water cycles, combined with a heavy volume of traffic, can create surface depressions which may eventually lead to cracks and potholes.

Solution: Make sure there’s a proper drainage system in place to divert the flow of water away from the pavement. Building gutters and concrete culverts help prevent water damage.

One way to make your asphalt driveway last longer is to have it sealed every two to three years. Not only will it keep small existing cracks from worsening, but it will also restore your driveway’s sheen.

Cracks and potholes can be repaired through asphalt patching. It involves removing the damaged asphalt, repairing the base, and filling the area with either cold-mix or hot-mix asphalt.

Dumpsters

This is a common concern among property managers. Asphalt pavements can crack under the pressure of a heavy dumpster.

Solution: Place concrete pads or wood boards under the dumpster. These will cushion the asphalt pavement from the weight of the dumpster. If possible, avoid filling the dumpster with heavy debris such as bricks or dirt as the weight puts a strain on the asphalt surface.
