Kurzbeschreibung (Abstract)
The load-bearing capacity of traffic superstructures is usually assessed based on deformation measurements. The bearing capacity is defined as the superstructure’s resistance to short-term deformations. However, different measurement concepts and evaluation methods are required for different superstructures to assess the bearing capacity. Therefore, this paper will present various methods for road and tramway superstructures and illustrate them with practical examples. The bearing capacity of road pavements is typically assessed by deflection measurements using the falling weight deflectometer (FWD). This dynamic measurement method applies a falling weight to the road surface, and the resulting deflection basin is recorded briefly. This can then be evaluated. Evaluations of various measurements in Germany are presented. The assessment of load-bearing capacity in the tramway sector is not currently established in German regulations. An individual measurement concept was developed and applied to assess the load-bearing capacity in urban transportation. The measurements aimed to determine the in-situ deformations of the grooved rail with a selected type of fastening during the passing of trams. In addition, the serviceability during operation was checked. The measurements were carried out on an open construction (grass track) and a closed construction (asphalt), as well as in tight curves and on straight track sections. Based on the deformations determined, conclusions can also be drawn about the service life.
