Several pavements were tested with a wheel tracking device todetermine the fatigue performance. The use of the visco-elasticmethod (with a dissipated energy criteria) was compared to elasticanalysis for those pavements tested. Strains measured in testtracks show that, in the longitudinal direction, compressive strainsoccur which are followed by a tensile peak and then compressivestrains again, whereas, in the transverse direction, the strainis all tensile. If a visco-elastic model is employed, non-symmetricalstress/strain responses can be calculated. Further analysis illustratesthat using asphalt material properties associated with a visco-elasticmodel the effect of multiple wheel passes on the strain responsecould be explained with reasonable accuracy. Analysis of pavementsproduced a similar ranking to the performance obtained in thetest pavements and indicated that as temperature is increased,life decreases, consistent with fatigue calculations by othertechniques.
