• Abstract:
  Recycled concrete aggregate (RCA) is often used ; as a replacement of virgin aggregate in road ; foundations (base course), embankments, hot-mix ; asphalt, and Portland cement concrete. However, ; the use of RCA in exfiltration drainage systems, ; such as French drains, is currently prohibited in ; many states in the U.S. The French drain system ; collects water runoff from the road pavement ; and transfers it to slotted pipes underground ; and then filters it through coarse aggregate and ; geotextile filter fabric. The Florida Department ; of Transportation (FDOT) requires No. 4 size ; aggregate for French drain applications. The ; primary concerns with using RCA as a drainage ; medium are the fines content and precipitation of ; calcium carbonate, which can reduce filter fabric ; permittivity. Additional concerns include the ; potential for re-cementation of RCA fines.
