Asphalt paving is the preferred choice when it comes to building roads that last. Both easy and inexpensive to install, this material offers impressive structural integrity that can support traffic for several decades. To maximize its performance, road management crews must stay aware of surface wear and all the elements that cause it. The guide below discusses factors that can contribute to asphalt wear and how to prevent damage.  

3 Factors That Erode Asphalt Roads

1. Water

When standing water penetrates asphalt, it softens the binding agent and displaces aggregate, causing the surface to gradually deteriorate. In cold temperatures, moisture in the pavement may also freeze and expand. This freezing can cause cracking and potholes. If the road experiences heavy traffic, then the potholes will likely grow due to the excess weight.

Sealcoating the surface about once every three years will add a protective layer that prevents moisture penetration. Prompt snow removal and proper drainage solutions can also keep water from collecting on the pavement.

2. Sunlight

UV rays from sunlight cause asphalt to oxidize, which accelerates the aging process. Over time, this oxidization will cause the surface to fade, crack, and crumble.

Sealcoating is the best way to protect the surface from sun damage, as this protective layer will deflect harmful UV rays.  

3. Fuel & Oil

Fuel and oil that spills out from vehicles will change the chemical composition of the asphalt’s binding agent. At first, this damage may only result in staining. Eventually, the fluids will soften the asphalt so that it is more susceptible to damage.

In the winter, extra fuel and oil can mix with snow and undergo the freeze and thaw cycle, which causes potholes. Regular sealcoating can prevent these chemicals from penetrating the surface, as well as protect the material from road salt.
