Extreme Heat Can Cause Pavement Buckling

With substantially hot and humid weather conditions on the way, the Wisconsin Department of Transportation (WisDOT) is reminding motorists of the potential for pavement buckling.

Hot temperatures cause pavement to expand, and where there are expansion joints, the slabs of pavement push against each other. If the pressure becomes great enough, the pavement can buckle. While it’s difficult to predict if or where buckling may occur, WisDOT offers the following tips for motorists:

  • Slow down, buckle up and eliminate distractions to focus your full attention on the roadway. Along with pavement issues, other concerns this time of year include deer or debris on the roadway.

  • Watch for slowing traffic, and be ready to Move Over for all roadside workers including highway crews as they repair damaged pavement.

  • Before your trip, check 511 Wisconsin, the department’s free 24/7/365 traveler information system, for the latest on any incidents or delays.

If necessary, report serious pavement issues by calling 911. Be ready to provide specific location information
