Beneficial Use of Dredged Material in Flowable Fill

US Army Corps of Engineers (USACE) annually dredge 300 million cubic yards nationwide to maintain channels’ navigation. Treating this huge amount of dredged material is a major challenge due to the mobilization of potential contaminants causing depreciation in water quality and depletion of valuable land. Rather than treating the dredged material as a waste, investigating alternative ways to recycle and reuse the dredged material is needed. Therefore, the aim of this study was to evaluate the feasibility of utilizing dredged material as a substitute for sand in flowable fill. A total of five mixtures were prepared by using different proportions of dredged material and virgin fine aggregates (sand) in flowable fill. Each mixture was tested for flowability and compressive strength. Both flow consistency and strength results were found within required specification for flowable fill.
