Evaluation of Recycled Base Aggregates

Recycled asphalt pavement (RAP) and recycled concrete aggregate (RCA) are materials processed from existing pavements and used in new pavement construction projects. The environmental and economic benefits of reusing waste materials have made RAP and RCA popular in base course applications in Wisconsin for more than 30 years.
