Ballasted Track Superstructures: Performance of Innovative Railway Sleepers
Civil-Comp Proceedings, 2012A railway sleeper is the structural element which transversally connects the two rails by means of fastening components, thus ensuring its gauge. Its additional function is to firmly secure the track to the ballast and to distribute the loads transferred from railway carriages to the ballast. One of the most important parameters in the characterization

Influences of ballast degradation on railway track buckling
Engineering Failure Analysis, 2021Abstract Presently, railway track buckling, caused by extreme heat, is a serious issue that causes a huge loss of assets in railway systems. The increase in rail temperature can induce a compression force in the continuous welded rail (CWR) and this may cause track buckling when the compression force reaches the buckling strength.

Infrared thermographic investigation of railway track ballast
NDT & E International, 2002Abstract A theoretical study was undertaken to determine if infrared thermography is an appropriate method to identify the condition of railway track ballast. Within this study the optimal conditions for an infrared survey were established. A laboratory experiment was undertaken to identify clean and spent ballast using an infrared camera.

Deflectometer-based analysis of ballasted railway tracks
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2007The falling weight deflectometer (FWD) device is used in the UK for the dynamic testing of ballasted railway track. Using the deflection data obtained from the test, elastic modulus values of the track substructure required to build a numerical model of the track can be determined using a procedure known as back-analysis.

Dynamic behaviour of ballasted railway tracks: A discrete/continuous approach
Computers & Structures, 2005Owing to the small number of grains in the vertical direction of the ballast layer of a railway track, a discrete/continuum double-layer model is proposed: the upper layer (the ballast) is modelled by a discrete 3D-lattice of interacting grains whereas the infinite underlayer is a continuum linear elastic medium.
