摘要:The fatigue failure form of asphalt pavement is not reflected in the design index of asphalt mixture proportion when determining the optimum asphalt content in the existing asphalt mixture proportion design. In order to solve the problem, the effect of different asphalt content on the fatigue life of three types of asphalt mixtures was studied by indirect tensile fatigue test.The results show that: (1) the splitting strength of asphalt mixture decreases with the increase of asphalt content; (2) the fatigue life of asphalt mixture increases first and then decreases with the increase of asphalt content; (3) the order of sensitivity of fatigue life of three types of asphalt mixture to asphalt content is: AC-5 > STRATA > ATB-25.Some useful suggestions are put forward for the design of asphalt mixture with good fatigue resistance.
