Abstract: 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 a 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.

Keywords: heavy vehicles; mathematical modelling; road damage; vehicle suspensions; suspension dynamic response; vehicle-road interaction; simulation; viscoelasticity; tyre inflation pressure; suspension stiffness; load level; road roughness; vehicle configurations; strain energy.
