High Temps Mean Metro Roads More Prone to Buckling

With the hot temperatures Monday there is a concern of buckling pavement in the metro.

Crews from the Minnesota Department of Transportation have been monitoring the hot highways all across the metro, and so far there have been no pavement problems. 

The potential increases around rush hour when the heat has been building all day, and the extra rush-hour traffic increases pavement temperatures, according to MnDOT.

Buckling happens when the road surface heats up, expands, becomes deformed and causes a traffic tangle. It can happen anywhere, but typically concrete is more prone than asphalt because it's not as flexible, according to MnDOT.

The age of the roadway can make a difference too. "We generally see it happen more on older concrete roads that may have some cracks," said Kirsten Klein with MnDOT.

More potential problems are tire failures and cars overheating. MnDOT said if your car is not prepared, hot days like today will be the day they breakdown.
