3차원 입체평면을 가지는 프리캐스트 슬래브궤도(3D-PST)의 개발

3D-PST is 3-dimensional precast panel producing technology. The panel has curved shape for vertical, horizontal direction and cant for each location. It is effective to secure the quality and to increase the durability of track because of the excellent curving performance to the precise construction. It is possible to produce systematically for panel-integrated type and separated type, including application for conventional wheel-rail track, rubber-tired runway and embedded track. Until now, the primary development process was undertaken through the design, manufacture and construction. The verification is performed on test line at now.
