MoDOT officials checking for potholes
Tuesday, March 15, 2011
Missouri highway crews are on the lookout for potholes on state roads amid the rising and falling temperatures of late winter.
The Missouri Department of Transportation says warmer weather sends melting snow seeping into cracks and joints in pavement. If temperatures drop, the water refreezes and the pavement expands, then heaves and breaks — causing a pothole.
Work crews are checking for potholes and can make temporary repairs. But permanent fixes require more durable asphalt and have to wait until winter is done.
The agency also is repairing road stripes that have been damaged by snow plows.
