ACPA's "Recycling Concrete Pavements"(EB043P) is a comprehensive guide that addresses facts about recycling concrete for use in new concrete pavement structures

The 102-page technical resource describes concrete pavement recycling as a proven technology that offers an alternative aggregate resource that is both economical and sustainable. Concrete recycling is a relatively simple process that involves breaking, removing and crushing hardened concrete from an acceptable source to produce recycled concrete aggregate (RCA), a granular material that can be produced for any application for which virgin aggregate might be used. Concrete pavements are 100 percent recyclable.

The publication begins with an executive summary and an introduction, and then, continues with chapters covering production, properties and characteristics; and uses of RCA, as well as properties, performance, and recommendations for concrete pavement structures containing RCA. A number of very helpful appendices follow, including guidelines for removing and crushing existing concrete; using RCA in unstabilized (granular) subbases: and using RCA in concrete pavement mixtures. Additional appendices include AASHTO and ASTM standards, as well as a glossary of terms.
