Concrete Recycling May Cut Highway Construction Cost, Landfill Use

Purdue University civil engineers are working with the Indiana Department of Transportation (INDOT) to perfect the use of recycled concrete for highway construction, a strategy that could reduce material costs by as much as 20 percent. . . .

"Some parts of Indiana have plenty of quarries near highway construction sites," said Nancy Whiting, a scientiest with the Applied Concrete Research Initiative at Purdue's School of Civil Engineering. "In other places, it's more difficult to find quality aggregate. If you have to drive 50 or 100 miles to get a good quality aggregate, it's going to be much more cost effective to use recycled materials by crushing the concrete you have in place."
