Frost heaves pop up on Iowa roadways

Posted:

WATERLOO (KWWL) – Eastern Iowa drivers are in for a bumpy ride when they hit the road. The freezing and thawing we experienced last week is causing roads to buckle and form frost heaves. These annoyances are created when moisture underneath the road freezes and expands.

Shawn Streittmatter, the Manager at Boubin Automotive Services in Waterloo says these frost heaves can cause a mountain of damage to your car.

"I would say the bulk of the damage would be to the suspension on the exhaust due to bottoming out. Generally when you hit frost heaves you straddle them and pretty much directly underneath the car that takes the brunt of the force. The suspension on the other hand is at the wheel and if you hit those big deep holes just like pot holes it does a lot of damage too," said Streittmatter.

As for cost it depends on how much damage was done.

"It depends on the severity of the situation and how fast you were going and how big the frost heave that you hit was. I would say that would be the key to know how big of a fix it was going to be," said Streittmatter.

As for how to avoid paying this extra cost, Streittmatter says all it takes is a little common sense.

"Just slow down, take it easy though them and your expense will be a lot less, that's for sure."

Pavement experts say to prevent frost heaves the area of the road needs to be drained with tile, while ditches surrounding the area need be kept clean and free of clutter to allow water to flow away from the pavement.
