In the proposed study, the researchers propose construction of in-situ and full-scale French Drain systems and monitoring of long term recementation, drainage performance, and clogging buildup. As a long term goal, the researchers will investigate the beneficial use of recycled concrete aggregates (RCAs) as sub-drainage material in French Drain applications. The objectives of this research on the in-situ study of RCA French Drain are: (1) to evaluate the long-term calcite precipitation and recementation of RCAs under in�situ condition; (2) to develop field test methods to measure the drainage performance of in-situ and full-scale French Drain; and (3) to monitor long-term drainage performance and clogging buildup in the in-situ French Drain systems. |
