Kurzfassung englisch:
To optimize the structure and thickness of block and slab pavements as well as to test new large-format slabs an accelerated pavement test (APT) using the New Mobile Load Simulator (MLS10) was carried out in Austria from September to October 2010. The APT was an international cooperation with the Swiss Federal Laboratories of Material Science and Technology, the Austrian block paving industry and the Vienna University of Technology. The experiment included seven different types of slab and block pavements, and some were instrumented with soil pressure cells and horizontal strain gauges in order to assess the primary response under the moving wheel load. For the APT a wheel load of 65 kN was applied by super single tires of the MLS10. The test speed was 22 km/h and no lateral wandering and no application of water was used during the tests. Falling Weight Deflectometer (FWD) measurements were taken after construction of the test sections and after completion of loading. Deformation of the surface (rut depth) was determined periodically. The results of the APT are used to validate the parameters for a Finite-Element Model (FEM) specifically developed for slab and block pavements, which enables realistic simulation of the whole superstructure, traffic loads and thermal stresses. This FEM is used to optimize slab and block pavement design for industrial and heavy traffic areas.
