ST. LOUIS, MISSOURI ( KTVI ) - The Missouri Department of Transportation released a warning this week to all mid-Missouri drivers to be aware of potential pavement blow-ups. The warning comes as a result of the extreme heat.
The rain brought some relief from the heat, but the extreme temperatures have MoDOT warning drivers about buckling roads. "With the high temperatures we have had the past two weeks and these spot thunder storms and moisture getting into the pavement , you just really need to be careful and watch out because we are experiencing some pavement blow ups, said MoDOT District Maintenance Engineer, Becky Allmeroth.
MoDOT officials say spot showers and the hot weather create the perfect situation for so-called "pavement blow-ups. Parts of Interstate 44 at Boles Ave buckled early in the week.
There have been about 50 already in the region and drivers should be on the look- out for more as they travel labor day weekend.
A pavement blow-up occurs when the roadway surface expands at a crack or joint where moisture has seeped in. That crack weakens the pavement and the heat causes the pavement to buckle and warp.
While it is difficult to know where or when a pavement blow-up will happen, crews with the Missouri Department of Transportation are monitoring state routes for these blow-ups and will make repairs as soon as possible.
“We have the perfect recipe for pavement blow-ups with consistent temperatures in the high 90’s coupled with spot rain showers. We have several areas that have already been repaired and several more that we are keeping an eye on,” said District Maintenance Engineer, Becky Allmeroth.
Motorists can report pavement blow-ups, or any other roadway concerns, by calling MoDOT’s toll-free customer service center at 1-888-ASK-MODOT (275-6636), or online at www.modot.org.
