Track ballast modelling by discrete element method

Građevinar, 2019
An increase in axle load and travel speed causes faster degradation of track structure and, hence, of the ballast prism. Crushing of stone grains in ballast due to excessive contact forces among these grains causes degradation in the form of filling of voids and, in turn, in poorer drainage, which can cause structural failure.
