• Abstract:
  "Crushed concrete aggregate (CCA) is granular material manufactured by removing, crushing, and ; processing old concrete for reuse as an aggregate source in new construction. Although the Michigan ; Department of Transportation (MDOT) has used CCA since the 1980s, issues in the performance of ; some of the early projects currently limit its use to primarily bound and unbound drainable bases beneath ; concrete pavements. Some of the performance issues on the early projects developed because of the ; unique characteristics and properties of CCA materials, such as increased absorption, lower specific ; gravity, and reduced abrasion resistance. ; Although there are potentially some limitations associated with the use of CCA, the effective ; characterization of these materials during their production and throughout the design and construction ; process can help lead to their successful use and application. This document is intended to help guide ; MOOT engineers in using CCA in the State's transportation infrastructure, with particular focus on ; pavement applications. Information is provided by chapter on the processing and production of CCA, on ; the physical, mechanical, and chemical characteristics of CCA, and on the use of CCA in base layers, ; asphalt paving layers, and concrete paving layers; these are presented in conjunction with MDOT's ; standard specifications for construction and and special provisions to indicate the Department's current ; usage policies policies and recommendations regarding CCA."
