Behaviour of Asphalt Mixture under Large Amplitude Cyclic Loading

This paper presents a study on the behavior of asphalt mixture under large amplitude cyclic loadings. A special cyclic loading path was applied during homogeneous test on cylindrical specimen kept at constant temperature. The test included loading periods, unloading periods, rest periods and the measurement of complex modulus E* and complex Poisson’s ratio v* at different frequencies and different strain levels. A few loading/unloading cycles in large strain domain (up to 6% strain in compression) at constant strain rate were carried out. The measurements of E* and v* were performed in applying some small strain amplitude sinusoidal cycles. The results are analyzed in axial stress-axial strain axes and volumetric strain-axial strain axes. Trends similar to the one observed for unbound granular materials are obtained. The evolution of E* and v* during the test are compared with stiffness and Poisson’s ratios at the beginning of large loading cycles.
