Cover Story: Non-destructive testing based on elastic wave propagation is well established for solids. In the field of infrastructure, there is great potential for applying these methods to base courses of granular material. The detection of inhomogeneous compaction makes it possible to optimize construction and maintenance processes, e.g., for railway superstructures. Using sand as an example, the presented study shows that there is a nonlinear correlation between the stress state in granular material and the propagation velocity of ultrasound. The laboratory tests were carried out using a servo-hydraulic press and a measurement box. In follow-up investigations, it is planned to further develop the test equipment for coarse-grained materials such as railway ballast. View this paper
