By the year 2000, approximately 20,914,000 cubic yards of material will be dredged in the Port of New York and New Jersey region. Under the new joint dredging plan for this region, 9,114,000 cubic yards of this material is classified as Category II and III, non-ocean disposal material. Without ocean disposal, the contaminated material must be stabilized of contaminants before any placement can occur. The Newark Bay dredged material was treated with three different pozzolanic admixtures prior to laboratory tests; portland cement (PC), cement kiln dust (CKD) and lime kiln dust (LKD). Each mix was then tested for material properties and strength characteristics using soil classification, resilient modulus, and triaxial compression tests. The shear strength of the treated material was found to be sufficient for a wide range of geotechnical applications such as embankments, subgrades of roadways, and structural and non-structural fills. Toxicity Characteristic Leaching Procedure (TCLP) tests conducted on the treated material found no detectable levels of contaminants (heavy metals, PCB's, etc.) present once stabilization occurred.
