5 Different Types of Asphalt Damage

With proper installation and regular preventative maintenance, you can easily avoid most damages to asphalt paving. However, if your asphalt surface begins showing any signs of damage, it is essential to repair them right away to avoid more extensive deteriorations that come with costly repair bills. Our experts on asphalt paving and sealcoating in San Antonio, TX, offer the following types of asphalt damage to be on the lookout for in your pavement:

Stripping

Stripping happens when the adhesion between the aggregate and asphalt becomes weak, causing the surface to become dislodged. This damage can quickly lead to the formation of cracks in asphalt paving.

Base failure

Base failure can result from installation errors, a lack of support, too much weight in a particular area, and poor drainage. Repairing base failure requires removing asphalt's surface layer to access the subbase.

Depressions

Depressions are areas on your asphalt surface with lower elevations than the rest of the pavement. Pavement depressions generate standing water, leading to more significant damages down the line.

Potholes

Potholes result from heavy traffic on the pavement and wear and tear caused by weather elements. You usually discover most potholes toward the end of winter or early spring because water is constantly exposed to the freezing and melting cycle. When this water has made its way into the base of an asphalt structure, it will weaken the pavement. Preventative maintenance can help you minimize or prevent this type of damage to your pavement.

Cracks

Transverse cracks

These cracks form perpendicular to the centerline of your pavement. Transverse cracks will develop when there are issues in the underlying layers of an asphalt structure.

Longitudinal cracks

The poor construction of longitudinal joints generally causes this type of cracking. As a result, you will find longitudinal cracks running parallel to the centerline of your pavement.

Block cracks

These damages can be identified by their interconnected series of cracks that usually resemble rectangles. Block cracks result from shrinking and expanding the asphalt binder during temperature changes. They are a direct result of laying an asphalt mixture that is too dry.

Edge cracks

As suggested in the name, the cracks develop close to your pavement's outer edge. They can result from a lack of support and heavy vegetation at the edge of your pavement.

Slippage cracks

This cracking forms because of a poor bond between pavement layers or an asphalt mixture that is too weak. These cracks are unique and recognized by their similarity to stretch marks.

Alligator cracks

Alligator cracking, also known as pavement fatigue, is typically caused by overloading. In addition, these cracks can form due to a problem with your pavement’s subbase or your pavement being too thin.

These are just some of the damages you may discover in your asphalt pavement. Please remember that it is essential to repair these damages as soon as you notice them to avoid more extensive deteriorations and costly repairs in the future.
