Recycling shingles for use on roads is nothing new. They can prevent potholes and slow binder aging. And though recycled shingles take a little getting used to, they are becoming increasingly popular.

Now one Wisconsin county is adding shingles to its roads.

Following a hailstorm this summer that damaged many roofs in Manitowoc County, Wisconsin, the county began recycling shingles to use as asphalt, reports.

County Public Works Director Jeff Beyer noted that the process lowers costs for asphalt companies, saves space at landfill sites and is a cheaper option for residents and business owners repairing their roofs.

Todd Schoenwalder, site manager for Green Bay-based Forward Vision Environmental, said Northeast Asphalt is purchasing the asphalt and will grind it up to incorporate it in asphalt mix. He added that the shingles will make up about 15 percent of the asphalt mix.

The report notes that the shingles consist of material that is similar to that of hot mix asphalt, allowing it to be combined with the asphalt for road construction.

Manitowoc County began the shingle recycling program in September, and as of October 21 had received about 1,250 tons of shingles.
