Abstract
Reservoirs in Taiwan have been experiencing severe siltation problems due to unfavorable environmental conditions and numerous harmful human factors. This research conducts a bench scale experimental study to explore the potential of using reservoir siltation (RS) in controlled low strength material (CLSM) particularly for subgrade applications. Test results show that RS can be used for producing of acceptable CLSM through proper mix design procedures. Considering the requirements of pavement subgrade constructions, this study recommends a water/solid ratio of 0.7~0.8 and a cement/water ratio of 0.4~0.5 can be used for the design. The study proposes a promising solution to reuse reservoir siltation, save natural resource of granular fill, and ensure the quality of pavement subgrade constructions in most cases.
