3 Types of Damage Asphalt Sealing Prevents, 9, Tennessee

Asphalt sealing is an important part of maintaining a driveway or parking lot made of this material. It should be performed every two to three years to protect the pavement from developing damage that could shorten its life span. If you miss this maintenance, you could develop one or more of the issues below.

What Can Happen When You Skip Asphalt Sealing

1. Freeze-Thaw Expansion & Fracturing

The winter can be absolutely brutal on asphalt, particularly due to the freeze-thaw cycle. This occurs when water seeps down into the pavement, freezes, and expands — resulting in cracks. As the water thaws, it will then creep even deeper into the material, repeating this process and leading to numerous fractures. Asphalt sealing prevents this by covering any small cracks in the material and keeping water out year-round. 

2. Sun Drying

The chemical bonds in the pavement begin to deteriorate, leading to cracks and other damage on the surface. Asphalt sealing prevents this by covering the blacktop in anti-oxidation additives and other aggregates that act as a barrier. 

3. Surface Softening

Since asphalt pavement is predominantly used by vehicles, it will most likely experience some auto fluid spills. When oil, gas, and similar liquids fall onto the surface, they will be absorbed by the asphalt and cause it to soften. While these spills can be easily cleaned up in most cases, overtime they can result in cracks or a deterioration of the aggregates comprising the blacktop.
