Hot weather increases chances for pavement buckling

Drivers asked to be alert for potential pavement problems, traffic slow-downs, and to Move Over for roadside workers including highway repair crews

Release date: June 26, 2019

With hot, humid weather in the forecast, officials with the Wisconsin Department of Transportation (WisDOT) are asking motorists to be alert for the potential of pavement buckling - and for highway maintenance crews making needed repairs.

Pavement buckles are most common during the first few heat waves of the season when the weather quickly goes from cool to very hot, causing pavement to expand. This can cause slabs of pavement to push against each other, and if the pressure becomes great enough, the pavement can buckle. While it’s difficult to predict exactly when or where buckling may occur, WisDOT offers the following tips for motorists:

  • Ensure all vehicle occupants are buckled up. Slow down, eliminate distractions and scan the road ahead carefully.
  • 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 the 511 Travel Information system (511wi.gov) for the latest on any incidents or delays.
  • Report serious pavement issues by calling 911. Be ready to provide specific location information.
