In this study，a series of triaxial creep tests of core asphalt concrete were conducted with the temperature controlled as 5℃，10℃，and 15℃，respectively，relying on an embankment dam with asphalt concrete core (ACED) located in the west of China. The test result indicates that a linear relationship is satisfied between the shear creep strain and time in the double logarithmic coordinates. The slope for the lines corresponding to the different deviator stress changes slightly，while exponentially decreases with the increase of the temperature. The shear creep strain at different time increases nonlinearly with the increase of the deviator stress，and this nonlinear behavior becomes more obvious with the increase of temperature. Moreover，with the increase of the temperature，the creep rate is accelerated，and the creep deformation is also increased. Larger creep deformation is observed under the action of larger deviator stress. The volumetric creep strain is greatly influenced by the value of deviator stress，which shows the compression in the low deviator stresses and the dilatancy in the large deviator stresses. Furthermore，the dilatancy is remarkably larger than the compression deformation. Besides，the influence of the confining stress on the creep of asphalt concrete core is also dependent on the value of deviator stress. The creep under different confining stress changes slightly in the low deviator stresses，while decreases with the increase of confining stress in the high deviator stresses.
