Even though there's water on the ground, crews can still use a special mixture to fill potholes. It's not perfect and when it's wet, it may not last as long. But, IDOT supervisors say it's better than leaving big, gaping holes in the ground.
Crews cover state roads like North Prospect, Mattis and Springfield, in Champaign. What they do is shovel out the patch and tamp it down. They don't harden as much as the asphalt, but right after that, it's settled enough for cars to drive on.
IDOT's District 5 covers seven counties; Champaign, DeWitt, Douglas, Edgar, McLean, Piatt and Vermilion. The department usually spends about $574,000 a year in labor, equipment and materials for filling potholes. So far, since July, it's spent about $385,000. It's a little above average.
If the temperatures dip below freezing again, those patches could expand and pop back out, so crews would have to come back out and fill them again.
