An assessment of the relation between pavement stored energy and road damage is presented. This assessment is based upon mathematical models of different heavy duty vehicles and pavement configurations. Vehicle-road interaction is simulated assuming that the pavement behaves as viscoelastic material and the vehicles perform as linear multibody spring damped mass systems. Variation in a tyre's inflation pressure, suspension stiffness, load level, and road roughness are analysed as a function of different vehicle configurations. Based on this simulation, a level of friendliness as a function of pavement accumulated strain energy, is associated to each vehicle configuration.
