This paper is a review of the effect of vehicle characteristics on ground-and track borne-
vibrations from railways. It combines traditional theory with modern thinking and uses a …

Traditional ballasted tracks have been used intensively around the world with ballast as the
main material for tracks. Ballast has a significant contribution to the track alignment, stability …

Ballast plays a vital role in transmitting and distributing the train wheel loads to the
underlying track substructure. The load-bearing capacity, safe train speed, and the levels of …

This paper discusses the triaxial testing of a ballast material and a subballast material, which
are noncohesive, granular materials typically used for construction of a railway track …

An iterative procedure for numerical prediction of long-term degradation of railway track
geometry (longitudinal level) due to accumulated differential settlement of ballast/subgrade …

An elasto‐plastic material model is proposed that can be used to simulate the cyclic
deterioration of railway tracks. The model describes the envelope of the irreversible, plastic …

Railway track designers and maintenance entities have long been pursuing for a robust and
reliable method to predict the track's long-term behaviour. The complexity of this railway …

The frictional collapse of an assembly of equisized spheres is studied by a discrete element
model. The macroscopic constitutive response is determined as a function of the level of …

The geomechanical behaviour of railway ballast is a key aspect in the performance of
ballasted tracks, mainly under increased axle loads and/or train speeds. Recently, and …

This paper presents the results from a laboratory study in which the influence of metal-free
tire-derived aggregates (TDA) on the performance of ballast materials was evaluated. The …
