RESPONSE OF A ROADWAY LYING ON AN ELASTIC FOUNDATION TO RANDOM TRAFFIC LOADS

This paper analyzes the response of a roadway lying on a Westergaard foundation to the pressures of a load moving on a random profile at a constant velocity. The profile power spectrum is based on experimental recordings done on French roads. From the vibrating axle characteristics, the authors deduce the power spectrum of the exciting load. Then, they examine random bending vibrations so as to determine the expected mean square displacements of the roadway. They compare the results obtained for random and harmonic profiles.
