Why the Pavement is Buckling

The warm Memorial Day weekend caused over 30 incidents of pavement buckling statewide.
 
Kristin McHugh with the Wisconsin DOT says that's due in part to wide temperature variants and that there is absolutely no telling when and where the phenomenon will occur.
 

If you go from 60 degrees at night to 95 degrees at the peak of the afternoon, it's an extreme change from cold to hot and the heat makes the concrete expand.

 
That's why it's important to stay attentive to the road.
 
She says if you encounter a pavement buckle this summer slow down, and report it immediately through the 9-1-1 system.
