SUPPLEMENTARY NOTES16 ABSTRACTCrushed concrete aggregate (CCA) is granular material manufactured by removing, crusUsing Recycled Concrete in MDOT’s Transportation Infrastructure— Manual of PracticeFinal ReportPrepared For:Michigan Department of TransportationPrepa MDOT_Research_Report_RC1544_368544_7used 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 charactenstics and properties of C MDOT_Research_Report_RC1544_368544_7CA materials, such as increased absorption, lower specific gravity, and reduced abrasion resistance.Although there are potentially some limitations asMDOT_Research_Report_RC1544_368544_7
