A Baltimore Asphalt Contractor explains the Freeze Thaw Effect on Pavement

As your asphalt pavement ages, it will develop small cracks. This is just an inevitability. Even the best pavement begins to break down at some point, typically around 3-5 years after paving. If you ignore these early cracks, your asphalt could fail prematurely, especially when water is allowed to penetrate these cracks during the winter months.

The Freeze Thaw Effect on Pavement

When water penetrates asphalt cracks in the winter, it freezes, expands, and widens these asphalt cracks. This happens numerous times over the course of a winter, worsening asphalt cracks each and every time and degrading your asphalt surface from the inside out. The Result: Premature pavement failure.

Guess what? Maryland’s constantly changing weather makes things even worse!

“Any time you have weather where it is 60 degrees one day and 20 degrees the next, you’re going to have a significant impact on the pavement,” said Rob Morosi, Michigan Department of Transportation spokesman.

Cracks are just the beginning. Rapid freeze-thaw can even lead to potholes.

“Soil conditions will react differently, but essentially what happens is the top layer thaws while the soil stays frozen deeper down,” said Kirk Weston, managing director of the St. Clair County Road Commission. “You end up with moisture trapped between the frozen soil and the asphalt and as that drains, it makes the base unstable and you get potholes.”

Battling Back against the Freeze Thaw Effect

So how do you prevent the freeze-thaw effect from affecting your asphalt pavement? Crack filling! According to the Federal Highway Administration Manual of Practice (FWHA Report Number FHWS-RD-99-147), “Crack sealing and filling are imperative preventative maintenance tools.”
