JEFFERSON CITY, Mo. (AP) — In the spring it’s potholes but when temperatures soar into triple digits, motorists can face another, even more dangerous problem; buckling roads.
The Missouri Department of Transportation says extreme heat can cause pavement to “blow up.” The trouble starts when moisture seeps into a crack or joint, which weakens the pavement. The heat then causes the weak spot to buckle or warp.
MoDOT Maintenance Engineer Mark Giessinger says it’s difficult to know when or where the pavement will blow up. But he says crews will try to make repairs as soon as possible.
