THE SPEED EFFECT IN PAVEMENT DEFLECTION

The influence of vehicle speed on pavement deflection is a problem of obvious importance related to the evaluation of pavement performance. The fact that the deflections diminish with increasing speed implies a dissipative component in the system. A simple visco-elastic model is analysed which furnishes results in good agreement with empirical evidence and may be used in assessing the distortion pattern of pavements under idealized service conditions. Furthermore, relatively simple experimental procedures may be used to determine the required material parameters. /Author/TRRL/
