Abstract

This paper describes an experimental evaluation of engineering characteristics of dredged marine soils (DMS) which excavated during the dredging works carried out from Malaysian waters. DMS mainly consists of clays, silts and sands mingled with debris, rocks and organic matter. The samples were retrieved from Kuala Muda (Kedah) and Kuala Perlis. In laboratory works, physical properties of DMS are depends to space, time and land in the watershed. Due to its poor engineering properties, the material was destined for disposal offshore. Dredged marine soils, commonly classified as geo-waste. The parameters examined include particle size distribution, morphology, water content, Atterberg limits, specific gravity and organic content. The DMS from Kuala Perlis Kuala Muda Kedah can be classified as high plasticity of silt (MH) and low plasticity of silt (ML) respectively. Reasonable agreement can be noticed at different locations have different physical properties. Thus, the geo-characterization of DMS is significant in decision making either to be reused or disposed to the designated open waters
