Evaluate the Use of Reclaimed Concrete Aggregate in French Drain Applications, Summary Report.

摘要

RCA is rarely used as as a drainage material becuase its performance as a drainage material has been evaluated by few researchers. In this project, University of Central Florida researchers sought to improve the state of knowledge about RCA. They reviewed the available information related to RCA as drainage material. They conducted a survey of departments of transportation across the nation regarding use of RCA, particularly in French drains. Some state highway agencies reported use of RCA as base course; however, no state reported use of RCA in exfiltration drainage systems.
