    Abstract
  • The anti-shear properties of asphalt mixtures were studied through triaxial shear test.The influence of shear fatigue on shear strength was analyzed by using triaxial repeated load test.The relationship between anti-shear strength index and rutting index was observed.Analysis result shows that such factors as gradation type, asphalt content, asphalt properties and test temperature have great influence on the anti-shear strength of asphalt mixture.Anti-shear strength decreases exponentially with the increase of repeated loading numbers.The relativity between anti-shear strength index and rutting index shows good logarithmic function.The main reason of rutting formation is flow deformation resulted from shear fatigue.
