PennDOT RECYCLING MATERIAL BRIEF Recycled

throughout the United States is the use of Recycled Concrete Aggregate (RCA) in civil engineering applications. The reuse of concrete in roadway infrastructure dates back to the 1940s; specifically, the first documented use of recycled concrete in a transportation projects in the United States was a section of Route 66 in Illinois.
