Current backfill materials for shield tunneling are mixed with very high water cement ratio, often exceeding 200% to 300%. Those high water containing materials are easily consolidated and decrease its volume, which may cause ground loss. In the meantime, railway industry disposes huge amount of used paper tickets in daily basis and considerable cost is required for its recycling. This paper presents reuse of the train tickets for the backfill material. It is achieved both improving material properties and decreasing undesirable emission with the mixture containing the shredded tickets.
