Abstract

This study is part of research aimed at valorizing dredged sediments through the development of formulationsfor use in road engineering. The purpose of the study was to determine if the materials selected for pavement layerscomply with road design standards, in particular, with specific requirements for density, grain size, plastic properties, organicmatter, and mechanical performance. Methods: To determine the physical-chemical and mechanical characteristics of thedredged sediments obtained from samples taken from the Bakhadda dam located in western Algeria’s semi-arid climate,the sediments were treated with binders in small amounts (3% lime (L), 6% cement (C)) for reuse in road construction. Thestudy focused on the evolution of physical and mechanical characteristics of the treated sediments, including LL, PI, VBS,immediate bearing index (IBI%), UCS, tensile strength Ϭt, as well as small strain modulus ESS and large strain modulus E50.The results showed that adding lime and cement to the dredged sediments improved their strength, as evidenced bythe increased compressive strength (UCS) over time for the samples containing different amounts of binders (3%L,6%C, and 3%L + 6%C). Additionally, the effect of the water content on the mechanical properties of the formulations wasdemonstrated. The study showed that the strength increased when the water content decreased
