Modelling railway ballasted track settlement in vehicle-track interaction analysis
Transportation Geotechnics, 2021 Abstract The geometry of a ballasted railway gradually deteriorates with trafficking, mainly as a result of the plastic settlement of the track-bed (ballast and sub-base). The rate and amount of settlement depend on a number of factors, and for various reasons are difficult to predict or estimate analytically. As a result, various empirical equations

Wheel Flats in the Dynamic Behavior of Ballasted and Slab Railway Tracks
Applied Sciences, 2021 Wheel flats induce high-impact loads with relevance for the safety of the vehicle in operation as they can contribute to broken axles, hot axle boxes, and damaged rolling bearings and wheels. The high loads also induce damage in the track components such

Settlement behaviour of hybrid asphalt-ballast railway tracks [PDF]
Construction and Building Materials, 2019 The use of structural asphalt layers inside ballasted railway tracks is attractive because it can increase track bending stiffness. Therefore, for the first time, this paper investigates the long-term settlement characteristics of asphaltic track in the presence of a subgrade stiffness transition zone.
