Abstract

In order to study the behavior of railway ballast under vibration and the distribution of pressure under the ballast layer, experimental and numerical studies have been performed. A physical model of ballast was used to study repeated impact loadings in the laboratory. The instrumented equipment enables the measurement of vertical force at the impact and under the ballast layer.
