Use of Dredged Sediments from Newark Harbor for Geotechnical Applications


Under the Joint Dredging Plan for the Port of New York and New Jersey, New Jersey has committed to using stabilized dredged material for beneficial reuse. Under the short-term planning (1997–2000), an annual average of 1.39 million cubic meters of dredged material must be used. Laboratory tests were conducted to investigate the geotechnical properties of the Newark Harbor dredged sediments stabilized with portland cement. The material properties and strength characteristics were investigated using soil characterization, California Bearing Ratio, unconfined compression, unconsolidated undrained and consolidated undrained triaxial compression, and resilient modulus tests. Currently, portland cement stabilized dredged material is being placed as a subgrade layer for a future parking lot. Cone penetration testing was conducted on the material to evaluate the in-situ density of the deeper, compacted layers. Nuclear density tests were also conducted to verify compaction of the material. Correlations between the two in situ tests were developed to analyze the two-meter-deep structural fill.
