MoDOT warns to watch out for buckling roads

JEFFERSON CITY, Mo. (AP) - With temperatures forecast around 100, Missouri motorists are being warned to prepare for bumpy rides.

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.
