지속가능한 발전을 위한 궤도시스템의 LCA기법 적용 연구

초록

In this study, Among various rail track systems, Ballast and concrete track system of Seoul-Busan High-speed Line was adopted to quantify the amount of environment load through the LCA technique. It was intended to compare the results of both track systems through investigating life cycle inventory and gathering the material and energy flows of each track system. With applying the LCA technique to railway infrastructure, which simple maintenance was considered in the past, fundamental technology can be established for the sustainable development in the railway construction industry.
