Asphalt Deterioration and its Causes

Friday, August 10th, 2012

Asphalt pavement is the preferred material for most state and federal road projects for a few very good reasons. Most notably, asphalt is known for its durability, strength, resilience, and longevity. Still, even the toughest asphalt road or parking lot undergoes a lot of wear and tear, eventually deteriorating to the point of no return.

Over time the materials that make up asphalt begin to break down, affected by elements such as rain, sunlight and chemicals. Asphalt binder loses its natural resistance to water, allowing liquids to penetrate the surface and deteriorate the pavement.

Asphalt Deterioration and its Causes

  • Cracking: There are numerous different types of cracks, from alligator cracks and edge cracks to longitudinal cracks, block cracks, and more. When it comes to asphalt pavement maintenance and dealing with cracks, you have two basic options: crack sealing and crack filling.
  • Distortion: Caused by improper pavement construction and the deterioration of the underlying base, asphalt distortion includes : channels or ruts, corrugations and shoving, grade depressions, upheaval and utility cut depressions.
  • Disintegration: Asphalt disintegration includes potholes, raveling, and gas and oil spillage.

Asphalt must also be properly maintained and protected to maximize its lifespan.
