As temperatures begin to get closer to 100 degrees in Missouri, motorists should be aware that the extreme heat can cause pavement blow-ups on Missouri roadways.
A pavement blow-up occurs when the roadway surface expands at a crack or joint where moisture has seeped in. The crack weakens the pavement and the heat causes the pavement to buckle and warp.
"Several blow-ups have occurred on area routes. Missouri Department of Transportation crews are monitoring other state routes and will make repairs as soon as they occur," states a MoDOT release.
“We never know when or where a pavement blow-up will happen, but when it gets this hot outside, we’ll see them,” said Kansas City District Maintenance Engineer Lynelle Luther. “If you come across a blow-up, use extra caution, slow down and give us a call to let us know so we can respond and fix it as soon as possible.”
Motorists can call MoDOT’s toll-free customer service center at (888) ASK-MODOT (275-6636) to report pavement blow-ups. For more information about other MoDOT projects, visit www.modot.mo.gov/kansascity.
