摘 要：正Layered elastic analysis has been widely used in the structural analysis of heavy duty flexible ***,asphalt mixtures are well-known to exhibit time-dependent viscoelastic behavior,and consequently,results based on elastic behavior assumptions may not truly represent responses of an asphalt concrete *** the other hand,tire-pavement contact stress is traditionally assumed to be uniform,circular and vertical for pavement design and analysis approximations,while the actual tire-pavement contact stress is three-dimensional（3-D）,non-uniform,and non-circular,
