ROCKFORD (WIFR) -- This week's heat wave has Stateline road crews on high alert for buckling pavement.
After several ninety degree days in a row, roadways are feeling the stress. That results in expanding pavement but no where for it to go. This causes the road to bubble up. Rockford Street Division Operations Manager Mark Stockman says what starts out as a small bump, can quickly turn into a dangerous situation. Fortunately, the Stateline has avoided any significant damage so far.
"We have been very fortunate this year. We haven't seen any major defects caused by the heat. I have noticed a couple of minor ones here and there. Mostly on a blacktop streets that had a concrete sub-base underneath them," Stockman said.
Rockford is asking drivers to be on alert for buckles in the road. The risk is greatest when the temperature is over 90 degrees. So with cooler weather heading into the weekend, the threat should diminish.
