Crumb rubber (CR) has been proposed to apply in the ballast or sub-ballast layer for degradation mitigation and vibration (noise) reduction. The CR can change stiffness, which affect train-track-subgrade dynamic performance cause travel comfort safety issues. Towards this, this study aims at confirming 1) how much application of train layer; 2) what extent CR-ballast distribute loadings reduce ...

Dislocation structures can be directly related to the fatigue properties of metals, such as strength, including limit and saturation stress. We present an indirect dislocation-structure-based method evaluate local stresses for in-depth analysis sleeper screw failures, there is little knowledge about load these failures. The screw, fastening baseplates rails sleepers, a small but critical compon...

The train is a mode of mass transportation that fast, efficient, and relatively affordable. To support the high demand for this transportation, adequate infrastructure also needed. condition must always be monitored so level security safety rail modes can in optimal conditions. One important component requires regular attention maintenance railway sleepers. In paper, finite element (FE) model w...
