Field Performance and Durability of Eco-friendly Prestressed Concrete Sleeper

초록

order to dramatically reduce the usage of cement and natural fine aggregate as main ingredients of the concrete. It was already found that eco-friendly PSC sleeper satisfied its static/dynamic performances required by the Korean standard (KRS) and European standard (EN). In this study, the field performance of eco-friendly PSC sleeper was evaluated in the operating line of conventional railway, and its durability against extreme environmental conditions was tested as well. Based on the field monitoring and laboratory/field tests, the eco-friendly PSC sleeper can be an environmental as well as mechanical alternative to traditional PSC sleeper in railway.
