Experimental study of the gap between track slab and cement asphalt mortar layer in CRTS I slab track [PDF]
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.

A STUDY ON THE WHEELSET/SLAB TRACK VERTICAL INTERACTION [PDF]
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.

Modelling of Floating-Slab Track with Discontinuous Slab [PDF]
This paper presents three different methods for modelling a track with discontinuous slab under oscillating moving loads. These are the Fourier-Repeating-unit method, the Periodic-Fourier method and the Modified-phase method. The first two methods, borrowed from the literature of periodic infinite structures, are accurate if careful consideration is ...

Influences of cement asphalt emulsified mortar construction on track slab geometry status [PDF]
Purpose – The construction of cement asphalt (CA) emulsified mortar can obviously disturb the slab status after the fine adjustment. To decrease or eliminate the influence of CA mortar grouting on track slab geometry status, the effects of grouting ...

Energy harvesting from railway slab-tracks with continuous slabs
This paper contributes to the literature and development of knowledge in the topic of energy harvesting by presenting the modelling and calculations of energy from vibration of railway tracks due to moving trains on floating-slab tracks with continuous slabs, considering both the quasi-static and dynamic effects. The floating-slab track is modelled as
