| Abstract: | This study examines the compressibility of high-water-content dredged slurry treated with waste shredded tires (WST) and fly ash (FA). One-dimensional compression tests were performed on FA and WST stabilized slurry with varying WST contents (15%, 35%, 50%) and curing ages (3 h, 7 days, 28 days). Results show that adding FA and WST significantly reduces the compressibility of untreated soil. In detail, the compression coefficient of untreated soil stands at 1.19, whereas treated soil samples demonstrate a significant reduction of 64%–86%. Similarly, the compression index of untreated soil is 0.167, while treated samples exhibit a decrease of 19%–83%. Compared to a linear e-lgp curve observed in untreated soil, treated samples exhibit two distinct straight-line segments with the intersection related to the compression yield stress. Compressibility indices, as well as the rebound index during unloading, increase with higher WST content and decrease with longer curing time. Specifically, the compression index of mixed soil samples increases linearly with WST content. Conversely, when considering curing age, the compression index and rebound indexes decrease rapidly before leveling off. In both cases, compression yield stress shows a quick increase that eventually stabilizes. SEM analysis of treated samples reveals a denser microstructure and improved particle bonding.
