Abstract

In this study, an attempt has been done to figure out the geotechnical properties of physically remolded dredged materials of the Gulf of Izmit located in NW Turkey, by using slump test method. For this aim, slum tests were conducted on dredged material specimens using open-ended polyvinyl chloride (PVC) cylinders of 10 cm diameter and height. Water content of the dredged material specimens was obtained in the laboratory using oven method. Bulk wet density, Atterberg limits and phase relations such as bulk unit weight, % solids by weight, void ratio, and engineering behavior properties such as Vane shear strength, and effective stress were determined. Later, the statistical correlations were conducted by regression analysis to obtain the relationships between water content and slump/cylinder height as well as other parameters such as wet bulk density, % solid by weight, void ratio, Vane shear strength and effective stress.

Key words: Vane shear strength, dredged materials, slump test.
