레티스형 바이블럭 철근콘크리트 침목 표준 제정을 위한 요구조건 도출 연구

초록

Lattice-type bi-block reinforced concrete (RC) sleepers have been widely used for cast-in-place concrete slab tracks. However, the standards for manufacturing, inspection, and performance verification of the lattice-type bi-block RC sleepers are not well established, even when such a sleeper is a critical component of the cast-in-place concrete slab track. Therefore, it is necessary to develop a new standard for lattice-type bi-block RC sleepers. In this study, the requirements for the relevant standard were investigated through literature review. Domestic and international standards pertaining lattice-type bi-block RC sleepers were summarized and compared with each other. Consequently, the requirements for standard establishment were proposed.
