Experimental study of the gap between track slab and cement asphalt mortar layer in CRTS I slab track [PDF]
Journal of Modern Transportation, 2018 Gap exists in the interface of cement asphalt emulsion mortar and CRTS I track slab universally, which is more severe at four corners than other parts of the track slab.

Modelling of Floating-Slab Track with Discontinuous Slab [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 2006 A floating-slab track with discontinuous slab provides a spatially-varying stiffness under a constant moving load. When a train moves on such a track, even with the absence of rail roughness, a parametric excitation develops as wheels move up and down applying dynamic forces at the wheel-rail interface.

Quality of Slab Track Construction – Track Alignment Design and Track Geometry [PDF]
Civil and Environmental Engineering, 2015 Abstract The slab track superstructure design (without ballast) is a perspective construction especially for building tunnels and bridges in the modernized sections of railway tracks in Slovakia. Monitoring of the structure described in this article is focused on the transition areas between standard structure with ballast and slab ...

Effect of temperature gradient-induced periodic deformation of CRTS Ⅲ slab track on dynamic responses of the train-track system [PDF]
Railway SciencesPurpose – Temperature is an important load for a ballastless track. However, little research has been conducted on the dynamic responses when a train travels on a ballastless track under the temperature gradient.

Modelling of slab track systems for design purposes
Journal of Engineering and Applied Science, 2023 Slab track is a recent technology used to cope up with the train high axle loads and speed, it has replaced the ballast material in classical ballasted track with either reinforced concrete slab or asphalt layer in order to increase both stability and ...

A STUDY ON THE WHEELSET/SLAB TRACK VERTICAL INTERACTION [PDF]
Fiabilitate şi Durabilitate, 2012 This paper deals with the interaction between a moving wheelset and a slab track due to the short-pitch corrugated rail. The wheelset is modeled using a free-free Timoshenko beam with attached rigid bodies as the axle boxes, wheels and brake discs.

Design methodology of slab track systems
, 2008 The substantial ballast wear in high-speed lines has led to the adoption of the slab track. In this paper a methodology for the calculation of the actions applied on the slab track and the design philosophy of such systems are presented.

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2017 An abrupt change in the stiffness of railway tracks at the junction between slab track and ballasted track causes increased dynamic loads, asymmetric settlements, damage of track components, and, consequently, increased maintenance costs. Due to this, a transition zone is usually built at the junction between the ballasted and the ballastless tracks to

Slab track optimisation considering dynamic train–track interaction [PDF]
, 2021 Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. Slab tracks generally have lower maintenance demands than ballasted track.
