An effective method for improving utilization of large quantities of surplus soil generated by construction works is required in light of the lack of waste disposal areas and a rise handling costs. Several methods have been tested including dehydration, ceramic, fusion, granularity, lime improvement, liquified stabilization, and so on. This paper presents the ReSM (Re-produced Soil Material) system that utilizes a modified concrete mixing truck installed with a projection to which wires are at.ta.ched to chum the contents inside the drum. This system mixes surplus soil with water and solidifieds and distributes them from the generating site to a. selected backfilling site directly. In this paper, laboratory data is presented to clarify the unconfined compressive strength and consolidation degree of ReSM, showing that the void ratio is large compared to that of natural soil. The test results prove that ReSM fully achieves the required standard for use as a back fill material. Furthermore, we introduce an example of shield-generated soil of 20,000m^3 back filled with homogeneous materials under the effective utilization of this method.
