Dane County -- As construction season picks up, some area roads are popping up. Literally.

Tuesday, Highway 12 near Waunakee was shut down for nearly two hours because of pavement buckling.

We're less than one week into summer, and some roads are already cracking under pressure.

So what exactly is it, and why does it happen?

Experts at the DOT say, when the road surfaces heat up they expand, and that's what causes the crumbling or buckling.

"Typically you'll see fractured concrete in front of you, or small pieces, laying on the roadway," said Steven Krebs.

The DOT says, it happens the this time of year the most, specifically early summer. They're also common when it's really hot out. Older roads are also a common culprit for pavement buckling.

Experts say, it's important to be careful on the roads, and be prepared to stop or make a maneuver. The DOT also says, if you're driving and come across a pavement buckle. The best number to call is 911 to report it.
