Abstract

A method for reclaiming hydraulically dredged material from a dredge reclamation area (DRA) having particular application for reclaiming hydraulically dredged virgin/new cut earthen material. The method involves the construction of training dikes and weirs in the DRA for draining water from saturated silts within the DRA and drying clay in the DRA in either a separate processing area or within the confines of the DRA by windrowing and by mechanical manipulation of the clay. The silts are then dried in the same way and mixed with the dried clay, either in a separate processing area or within the DRA. The resulting reclaimed material can meet industry standard density tests of 95% standard Proctor along with removing the moisture content to a 2%± of optimum moisture or better for use as structural or regular fill.
