How the weather affects roadways

Posted:

With the rise and drop in temperatures we're seeing and plenty of winter weather you might be thinking it's hard on your car, but roadways could be getting the real brunt of it.

With the freeze and thaw we keep seeing, MoDOT says roadways take a hit.

It's not just snow plows and salt causing damage either.

MoDOT's District Maintenance and Traffic Engineer, Jennifer Hinson says the thing that does the most damage is the salt and moisture combination,"It allows the moisture to get into that crack and then that crack when it gets cold. That expands and causes the pot hole."

She also says the cold weather causes the moisture in that crack to refreeze.

The constant change in temperature cause these cracks to expand and contract, and essentially create more damage.

Snow plows can also wreak havoc, pulling up surface material on some of its less traveled roads.

Hinson saysMoDOT's Northeast Missouri region spends around two to three hundred thousand dollars on pot hole filling material.
