Predicting Geotechnical Parameters of Fine-grained Dredged Materials Using the Slump Test Method and Index Property Correlations

Abstract : This technical note describes an innovative method for estimating selected geotechnical properties of physically remolded dredged materials using the proposed laboratory slump test and correlation equations. Material property assessment requires laboratory testing of dredged material samples. The index properties (including bulk density, void ratio, porosity, water content, percent solids, Atterberg limits, and specific gravity) are ultimately needed as geotechnical parameter inputs into the engineering planning, design, construction, operational, and management aspects of dredging and dredged material placement. This technical note explores innovative, non-standardized, and expedient methods to estimate numerous material index properties and engineering behavior properties without running standardized time-consuming and expensive laboratory tests. The proposed methods are presented only as optional engineering tools based on experimental data and are not intended to usurp any standard laboratory testing protocol.
