ACPA has released a new two-page document covering recycled concrete aggregates (RCA) and their use within new pavement structures. The document is part of the Association’s ‘Perspectives’ series, which inform the concrete pavement community about policies, practices and positions on key topics.
Eric Ferrebee developed the document to provide insights into what is now a standard and essential practice by the concrete pavement industry because of RCA’s numerous sustainability (economic, environmental and societal) benefits.
The two-page document explains RCA has been used successfully, is supported by the FHWA, and is specified in paving concrete pavement applications in over 40 states across the country.
The document also conveys both the primary application (for base/subbase layers), as well as secondary applications. Click here to download a copy of the document, which is included in ACPA’s ‘Perspectives’ library.
