This paper investigates the mechanical characteristics of monofilament-reinforced bottom ash mixtures for recycling dredged soil. Reinforced bottom ash mixture is a lightweight soil added with monofilament in order to increase its shear strength. Test specimens were fabricated by various mixing conditions including monofilament content, its length and its diameter. Then several series of unconfined compression tests and direct shear tests were performed to investigate mechanical characteristics of reinforced lightweight soil. The experimental results indicated that stress-strain behaviors of reinforced lightweight soil were strongly influenced by mixing conditions of monofilament content, its length and diameter. The compressive strength of reinforced lightweight soil generally increased by adding monofilament. In this test, the maximum increase in compressive strength was obtained at 0.5% content and 4cm length of monofilament. These results were similar to those of direct shear tests. The unconfined compressive strength of reinforced lightweight soil with monofilament of 0.25mm in diameter was greater than that of reinforced lightweight soil with monofilament of 0.5mm in diameter.
