Abstract

This paper presents a successfully executed project for the renewal an existing fixed railway track in a heavily frequented underground train station Zurich Airport by the application of ultra-high performance cementitious fibre reinforced composite material (UHPFRC). UHPFRC has so far been used mainly for the rehabilitation of road, roadways and railway bridges. The use of UHPFRC and novel technologies allowed to improve the existing fixed railway track, increase the service duration and reducing the construction cost by 30% compared to the traditional renewal methods. In frame of this project, the existing fixed railway track has been modernized in such way that the previous wearing components became part of the bearing structure. The minimum service duration of more than 100 years is expected for the improved fixed railway track. Furthermore, the use of UHPFRC to cast the new rail pedestals allowed to obtain uncracked structural elements for the anchoring of the rail fasteners, which
