A framework for applying slab track on earthworks in Norway [PDF]
, 2019 Fastspor er en sporkonstruksjon der skinner og sviller legges på en betong- eller asfaltplate. Fastspor gir normalt lavere byggehøyde enn spor med ballast, og gir ofte en mer stabil sporgeometri og krever mindre vedlikehold enn spor med ballast ...

Comparison of the technical performance of a discretely supported slab track system and an embedded slab track system in a high-speed railway [PDF]
, 2019 Slab tracks are increasingly used for High-Speed Railways (HSR) as opposed to the conventional ballasted track. This is due to many factors, including increased durability and sustainability, as the slab track can sustain higher dynamic loading with less

Full-scale experimental and field investigations into expansion mechanism of foamed polyurethane and its lifting behaviors for repair and maintenance of railway slab track systems [PDF]
Excessive settlement of the subgrade seriously reduces the service quality of slab tracks and threatens trains’ running safety. While the utilization of foamed polyurethane is recognized as an effective solution, previous research on its expansion ...

Differential railway track settlement in a transition zone – Field measurements and numerical simulations [PDF]
, 2023 In a transition zone between two different railway track forms, there is a discontinuity in track structure leading to a gradient in track stiffness. Examples include transitions between different superstructures, e.g., slab track to ballasted track, and/

The application of track deflection measurements made by the video gauge [PDF]
, 2018 This paper presents direct track deflection data measured by the Video Gauge (VG), (a Digital Image Correlation method) that is used to remotely determine track stiffness characteristics. Two cases are discussed.
