Recycling of Dredged Soil Waste Using Air-foam Stabilization Method as Highway Construction Material

Recycling of wasted soil becomes a hot issue due to the difficulty of disposal, whereas stiff soil is limited for construction. This paper investigates the properties of air-foam stabilized soil made from dredged soil recycled by air-foam stabilization method such as strength, resilient modulus, and evaluation of the pavement performance when using it as pavement sub-base material. Air-foam stabilized soil samples are prepared by mixing soil and water with various cement and air-foam contents. The unconfined compression test and the resonant column test are conducted; then, the relationship between the unconfined compressive strength and the resilient modulus of air-foam stabilized soil is evaluated. The resilient modulus values are applied in a layered elastic model to predict the allowable number of load repetitions based on fatigue cracking and rutting. According to the pavement performance, air-foam stabilized soil is sustainable and suitable in the role of pavement sub-base material.
