Crews working on pothole repairs

Fluctuating temperatures key to the problem

ANDERSON — With a temperature swing of almost 70 degrees in the space of a week, it should come as no surprise that potholes are popping up faster than weeds in the spring.

As the road surfaces undergo a constant freezing and thawing, which is continuing this week, the pavement begins to break up causing sometimes a “bone-jarring pothole.”

Potholes are formed after rain or snow seeps into the soil below the road surface, according to the Michigan Department of Transportation. The moisture freezes when the temperature drops causing the ground to expand and push the pavement up. As the temperature rises, the ground returns to a normal level, but the road surface remains rose, causing a gap. When a vehicle drives over the cavity, the pavement surface cracks and falls into the hollow space.

Crews with Anderson and Madison County are working daily to fill the potholes, while those in Elwood and Alexandria are reporting there isn’t a problem at the current time.

“We’re filling potholes with a vengeance,” Brad Lamb, superintendent of the Anderson Street Department, said Tuesday.

“We did a lot of paving the past few years where potholes were a problem,” he said. “The problem areas are on 53rd Street and Broadway.”

Land said the Street Department is using a cold patch that is heated in a hot box before applying to the road surface.

“With the freezing and thawing taking place, we anticipate more potholes,” he said.

Scott Harless, superintendent of the Madison County Highway Department, said the county has two Dura-patchers and three hot boxes working on filling potholes on county roads.

“So far we’ve only had one complaint,” he said. “Right now the crews are running the townships looking for potholes.”

Harless said he expects more potholes as the freeze-and-thaw pattern of Indiana weather continues.
