To optimize the thickness of slab and block pavements and also to test new large-format slabs an accelerated pavement test (APT) using the New Mobile Load Simulator (MLS10) was carried out in Aus-tria from September to October 2010. The APT was an international cooperation with the Swiss Federal Laboratories of Material Science and Technology, Semmelrock Ebenseer and the Vienna University of Tech-nology. The experiment consists of seven different 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 wheel load. For the APT the MLS10 used Goodyear super single tires with a wheel load of 65 kN. 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 in-tended to evaluate the parameters for a developed Finite-Element Model (FEM) for slab and block pave-ments, which enables simulation of the whole superstructure, traffic loads and thermal stresses. The FEM is the final tool to optimize the thickness of slabs and blocks for new designs and heavy traffic areas.
