Over time, asphalt will crack. That is an inevitability. Even the best asphalt pavement will eventually start to crack. The key to prolonging the life of your pavement is to manage these cracks as they occur, preventing them from growing and doing any more damage.
Common Types of Asphalt Cracking
1. Surface or Shrinkage Cracks: These cracks are caused by lack of traffic, extreme temperature changes, excess water and/or ultraviolet degradation.
2. Structural or Reflective Cracks: These cracks are typically caused by vertical or horizontal movements of pavement beneath, due to expansion and contraction with temperature and moisture changes.
3. Joint or Seam Cracks: These types of cracks are caused by weak seam or improper pinch roll.
Cracks allow water to penetrate your asphalt pavement, eroding the stone base and leading to further cracking, potholes, and eventual premature failure. And this process is accelerated during the winter months.
Crack Filling: The Key to Asphalt Longevity
“Crack sealing and filling are imperative preventative maintenance tools.” – The Federal Highway Administration Manual of Practice (FWHA Report Number FHWS-RD-99-147)
In fact, crack filling can extend the life of asphalt from 6 to 20 years. So what are you waiting for? Pick up the phone and call your local asphalt contractor at the first sight of cracking.
