T1 - A distinction between cyclically and dynamically loaded ballasted track T2 - 2nd International conference on railway technology: research, development and maintenance (Proceedings) N2 - This paper presents the impact of dynamic loading on the deterioration of ballasted track. Firstly it is discussed which types of loading can be observed at the track. The effects of cyclic and dynamic loading on the ballast assembly are discussed with respect to the different boundary conditions of physical model tests compared to those existing in reality. For dynamic loading, on the one hand, the displacements and rotations of single particles at the surface become more important. On the other hand, the load distribution caused by an impact like loading is different from a quasistatic loading. Finally, large scale tests are presented. When comparing the dynamic loading sequences with the solely cyclic loading, limits are found for a vibration level that is associated with an accelerated accumulation of permanent deformations.
