Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: The fatigue limit, a strain below which none or very little fatigue damage develops to materials, is the essential consideration in perpetual pavement (PP) design. This paper presents a study on the fatigue performance of asphalt mixtures in Bingzhou, China to determine this threshold for facilitating the process of devising designs and specifications for the construction of PPs. The strain levels for fatigue tests of asphalt mixtures in this study ranged from 70 to 400 micro strains. A nonlinear fatigue model was proposed to analyze different phases of the fatigue process of asphalt mixtures. The results were further interpreted by a weighted regression method to predict the fatigue life of asphalt mixtures and subsequently, determine the fatigue limit of PP. Based on the testing results of mixture fatigue performance and local condition in Binzhou, 120 micro strains and 70 micro strains were recommended as the fatigue endurance limits respectively for HMA-25 and ATB-25 in PP design of Binzhou, China.
