The Great East Japan Earthquake generated a huge amount of disaster-related waste. If soil generated from wood chips derived from woody waste materials is to be effectively used as a material in soil structure, the settlement and stability characteristics of this material should be considered. In this study, a series of laboratory tests was carried out, exposing soil composed of different ratios of wood chips to varying compaction degrees. The unconfined compressive strength decreased and the stress–strain curve exhibited more ductile behaviour as the wood chip content increased, while the opposite tendency was exhibited as the compaction degree increased. Deviator stress was not influenced by the mixing rate. The cement-mixed soil exhibited the effect of curing on strength properties, with crushed stone concrete-mixed soil displaying similar tendencies.
