RISSubstructure Nonlinear Effects on Sleeper Design Pressure in Heavy Haul Railway Tracks
Publisher: American Society of Civil Engineers
Abstract: This study focused on the effects of track substructure material nonlinearity on sleeper design pressure for conventional heavy haul railway ballasted railway tracks. The material nonlinearity was applied by using Mohr-Coulomb ...
Investigating Seismic Behavior of Ballasted Railway Track in Earthquake Excitation Using Finite-Element Model in Three-Dimensional Space
Publisher: American Society of Civil Engineers
Abstract: In this paper, a finite-element (FE) model including the track super- and substructure components was developed for seismic analysis of railway track. In the developed model, the beam elements were used to define rails and ...
Influence of Tire-Derived Aggregates on the Properties of Railway Ballast Material

Effect of Moisture on Performance of Mixture of Sand-Fouled Ballast and Tire-Derived Aggregates under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: The optimum weight percentage of tire-derived aggregates (TDAs) mixed with ballast, as a new approach to rehabilitate the performance of ballast layer in desert areas, has been suggested as 5% in the presence of sand ...
Dynamic Interaction of Vehicle and Discontinuous Slab Track Considering Nonlinear Hertz Contact Model
Publisher: American Society of Civil Engineers
Abstract: This paper develops a new two-dimensional numerical model of vehicle/discontinuous slab track dynamic interaction. The vehicle is simulated as a multibody system with 10 degrees of freedom. The slab track is represented ...

Dynamic Train–Track Interactions and Stress Distribution Patterns in Ballasted Track Layers
Publisher: ASCE
Abstract: This paper focuses on developing train–track dynamic interaction models by consideration of ballast and subballast layers’ stress distribution patterns. In this paper, the existing railway track pyramid models are more ...
