Railway superstructure for high-speed rails [PDF]
Acta Polytechnica CTU Proceedings, 2021 The construction of the track is solved as a conventional (with track ballast) or as a ballastless track (without track ballast). When deciding on the choice of the most suitable track design for high-speed rail, it is necessary to emphasize that with ...

Experimental Study on Vibration Characteristics of Unit-Plate Ballastless Track Systems Laid on Long-Span Bridges Using Full-Scale Test Rigs [PDF]
Sensors, 2020 In this work, we present a series of hammering tests on full-scale unit-plate ballastless tracks used for long-span bridges. There is no denying that it is a new attempt to pave ballastless tracks on high-speed railway long-span bridges; the related ...

Determination of the rail-to-earth transition resistance of the ballastless track and influence of the resistance on the current spreading in the subgrade [PDF]
Вестник Научно-исследовательского института железнодорожного транспорта, 2022 Introduction. The rail-to-earth transition resistance is an important parameter of electrified railways, which directly effects the electrical safety level of the traction network and the potential distribution in the upper structure track area.

Influence of temperature gradient of slab track on the dynamic responses of the train-CRTS III slab track on subgrade nonlinear coupled system [PDF]
Scientific Reports, 2022 Temperature is an important load for ballastless track. However, there is little research on the system dynamic responses when a train travels on a ballastless track under the temperature gradient of ballastless track.

Concrete mixtures with high-workability for ballastless slab tracks
Journal of King Saud University: Engineering Sciences, 2017 The concrete track-supporting layer and the monolithic concrete slab of ballastless track systems are made in-situ. For this reason the concrete mixtures of high workability should be used.
