Railway ballast permeability
Railway ballast serves as a major structural and drainage component of railroad track, but is known to degrade over time. This progressive degradation increases the amount of finer particles within the ballast over time, called fouling material, which decreases its drainage capacity and strength. …

Discrete Element Modeling of Railway Ballast for Studying Railroad Tamping Operation
… development of Discrete Element Model (DEM) of railway ballast for the purpose of studying the behavior of ballast particles during tamping is addressed in a simulation study, with the goal of optimizing the railroad tamping operation. A comprehensive literature review of applicability of DEM …

Discrete Element Modeling of Railway Ballast for Studying Railroad Tamping Operation
The behavior of the ballast particles during their interaction with tamping tines in tamping operation is studied by developing a simulation model using the Discrete Element Model (DEM), with the aim of optimizing the railroad tamping operation. A comprehensive literature review is presented …

Experimental and Numerical Study of Rubber Intermixed Ballast System Subjected to Monotonic and Cyclic Loading
… rock aggregates are the most demanded type of railway ballast worldwide, attributed to their favourable physical, geotechnical and mechanical properties. After a certain period of operation and fatigue under repeated loading, degraded ballast requires replenishment with freshly quarried …
