Major Factors to Degrading Asphalt


Since asphalt is somewhat porous, water can get into the tiny nooks and crannies within the pavement layer and cause the petroleum-based asphalt binder to separate from the aggregates inside. This can be caused by heavy weather or improper drainage leading to water pooling on the surface. When water freezes, it can expand and cause cracking.

Sunlight & Chemicals

Since asphalt is made up of petroleum based products, it needs oils to stay stable and firm. UV rays in sunlight can leech these oils out of the surface, causing it to dry up and become brittle. Chemicals spilling from vehicles can also break down the asphalt itself, resulting in pavement deterioration.

Vehicle Traffic

The weight of vehicles passing over asphalt pavement can make these other factors even worse. Tires push water and chemicals deeper into the pavement, and the pressure of heavy traffic physically breaks down the surface and can cause shifting of all pavement layers.
