A new framework for the prediction of fatigue failure life of asphalt pavements was presented. The new fatigue failure criterion based on energy dissipation theory, which was verified to be valid for wide range of mix stiffness modulus, was combined with the theoretical temperature estimation method. Traffic and environmental effects were incorporated into the new prediction system as probabilistic variables. In this system, the fatigue failure is assumed to take place at both top and bottom surfaces of the mix slab. With the method, an attempt was made to predict the fatigue failure lives for some routes of national highways in Japan, showing reasonable agreement between the predictions and the observations.
