Wooden-sleeper, which has been adopted as railway turnout in Korea, has created many problems such as short life span and increase of maintenance cost. Especially turnout on Maintenance Free slab track, which has been used in city metro, has been constructed with wooden sleeper buried in concrete roadbed due to complexity of structure. However, such problem as rapid erosion in subground makes it difficult to maintain the sleeper because of frequent replacement required. Therefore, the objective of this paper is to introduce design and construction of reinforced concrete(R.C) sleeper for turnout on the concrete roadbed to facilitate maintainability and economic construction of turnout.
