Service life evaluation of ballastless track construction

open access: yes, 2019
The article presents method for calculating service life of ballastless track structure using the track oscillation model as a structure containing three infinitely long beams, the lower of which lies on the modified Winkler base, and the upper and ...

Concrete mixtures with high-workability for ballastless slab tracks

open access: yes, 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.

Influence of Structural Parameters on Mechanical Properties of Double-Block Ballastless Track

open access: yes, 2011
A high degree of integrity is the most remarkable feature that makes double-block ballastless track different from other ballastless track structure. Based on the beam/plate theory on elastic foundation, influences of several structural parameters (such ...

Experimental Study on Fatigue Performance of CRTS III Ballastless Track-Girder System Considering Transverse Wheel–Rail Force

open access: yes
The CRTS III (China Railway Track System Type III)-girder is susceptible to fatigue damage under high-frequency train loads. However, existing research lacks sufficient focus on the CRTS III-girder and the transverse wheel–rail forces encountered ...
