UV Rays: The Enemy Of Asphalt Pavement

UV rays are a primary enemy of asphalt pavement. Over time, they can cause the surface to crack and deteriorate, leading to costly repairs.

In this blog post, Prime Asphalt will discuss the damage that UV rays can cause and the steps you can take to prevent it. Stay tuned for more!

How Bad Is It?

Since we can’t see ultraviolet (UV) light, it’s easy to forget its power. But make no mistake: UV rays are intense, and they can do some severe damage. They’re one of the leading causes of deterioration in asphalt pavement. Over time, UV rays can cause the pavement’s surface to crack and crumble.

This can lead to several problems, including:

  • Potholes
  • uneven surfaces
  • decreased lifespan of the pavement
  • increased repair and maintenance costs
  • driving hazards

All of these issues can be costly to repair, which is why it’s essential to take steps to prevent UV damage in the first place.

What Can Be Done?

We lather sunscreen onto our skin to protect ourselves from UV rays, and we should take similar precautions with our asphalt pavement.

No. 1: Sealcoating

One of the best ways to realize this is to seal coat the pavement surface regularly. Sealcoating creates a barrier between the pavement and the elements, including UV rays. It’s important to note that sealcoating is not a cure-all, however. It will not repair existing damage but can help prevent future problems.

No. 2: Slurry Seal

A thicker and heavier version of sealcoating, slurry seal is a good option for areas that see significant traffic or are subject to harsh weather conditions. Slurry seals can also help fill in small cracks and bumps in the pavement surface. This type requires at least 24 hours to cure, so be prepared for some traffic disruptions if you choose this option.

No. 3: Microsurfacing

Although more expensive than sealcoating or slurry seals, microsurfacing can further extend the life of your pavement. This treatment is perfect for larger parking lots or roads with a high traffic volume. It contains more polymer and aggregate with added asphalt residue in a slurry mix, which is then applied to the pavement and left to cure for a short time. After it dries, the result is a smooth, new surface.

No. 4: TRMSS

Tire rubber modified surface sealer, or TRMSS, works for areas like airport runways, highways, and other high-traffic areas. This sealer replaces oils that have dried out in the asphalt along with aggregate necessary for a new top layer. It also contains rubber from ground-up tires, which gives it its name. This addition makes the sealer more elastic and durable to withstand heavy traffic and extreme weather conditions.


While UV rays might be the enemy of asphalt pavement, there are ways to fight back and prevent damage. Proper maintenance and sealcoating allow your asphalt surface to last many years.
