Abstract:

A controlled field demonstration was conducted to evaluate the effectiveness of a methodology for reducing the volume and improving the physical characteristics of dredged material in confined disposal areas. The procedure involves the almost continuous conditioning of a layer of dredged material slurry by a tracked vehicle to accelerate evaporation of water in order to create a layer of soil from the slurry. The soil layer is then compacted with conventional construction equipment. A two-acre demonstration site was selected near Monroe, Michigan. The site was cleared the in situ silty sand was compacted and leveled and a 30-in.-high dike was constructed around the site. The site was divided into two test areas and a control pond. The water content of material in the control pond decreased from an initial 425 percent to about 186 percent at the conclusion of the demonstration. The concept of partitioning a containment area into several smaller areas should be considered where staged planning would permit filling operations in some of the areas while previously filled areas were being conditioned.
