Insight To Help You Deal With Two Types Of Common Asphalt Damage

When you are the owner of a property with asphalt paving, it is essential for you to maintain and take care of the asphalt to ensure it remains a durable surface for your needs. Asphalt is a flexible material that can become weakened along any of its unsupported edges and over an unsupportive base material. Here are some recommendations to help you repair and prevent these types of damage to your pavement:

Alligator-Pattern Cracking

One of the most serious types of asphalt damage appears as a web-like or alligator-pattern cracking over the surface of your pavement. Alligator pattern cracks occur as the sub base material below the asphalt was not installed properly and is eroding and settling, causing your asphalt to sink in and crack.

As a temporary fix until you can arrange for a permanent repair, patch the cracks over the area of alligator cracking, using an asphalt crack filler. You can then apply a sealcoating layer to seal in the damage and stop its growth. Then, mark off the damaged asphalt so you or other drivers do not continue to drive across its surface, as this can cause further damage with the cracking to spread over the pavement.

For a permanent repair, the area of damage will need to be removed and the sub-base material inspected to determine why it failed. A professional paving company or a contractor can help you with this repair. The sub-base should be replaced with several inches of compacted angular gravel to provide structure to the new asphalt layer you install. Installing your sub-base material with the existing soil or sand can cause the area to sink and cause cracking patterns.

Edge Deterioration

If the edges of your asphalt pavement have been installed without appropriate support from a structural material, such as paving stones, concrete edging, or gravel, the edges of your asphalt will begin to crumble. Over time, this crumbling will continue and work its way further into the surface of your pavement.

If your asphalt edges have been sloped downward, tapering off on the existing soil, you can help support the asphalt by backfilling a layer of gravel onto the sloped edges of the pavement. This helps prevent cracking by providing a supportive apron to prevent edge cracking when, for example, a vehicle drives off the edge of your asphalt.

If your asphalt's edges are not sloped, it is recommended to install an edging material, such as concrete edging, paving stones, or concrete blocks set into the soil and level with your asphalt. This provides the support to the edges of your pavement and prevents crumbling due to vehicle traffic over its edges and wear from the weather.
