Numerical and Experimental Development of an "Accelerated Repeated Rolling Wheel Load Simulator"
In the computational dimensioning of flexible pavements, special attention has to be paid to a realistic description of fatigue phenomena in asphalt layers caused by bending tensile stresses repeated millions of times. However, current experimental investigations show stress states and mechanisms of crack propagation that differ significantly from the states in real pavements.
