Abstract: To consider the complex mechanical behavior of asphalt mortar and provide the data surpport for asphalt mixture micromechanics analysis, several asphalt mixture mixing ratios were transferred into asphalt mortar mixing ratios. Asphalt mortar molding device and discovery hybrid rheometer fixtures developed by ourselves were used to obtain the dynamic shear creep curves. Burgers model was used to fit the creep curves. The viscoelastic parameters of asphalt mortar under dynamic shear loading condition were obtained. The changing rules of the viscoelastic parameters and the relaxation modulus were analyzed. Results showed that Burgers model had good fitting effect on dynamic shear creep curve of asphalt mortar. The creep deformation of SMA-16 corresponding asphalt mortar was larger than AC-20 within the same loading time. Rubber asphalt mortar had the optimal shear creep resistant properties. The asphalt mortar creep deformation had the same influence rules with the general influence rules of asphalt miture rutting deformation. Test temperature, asphalt contant, type of asphalt and aggregate gradation all had obviously influence on asphalt mortar dynamic shear creep viscoelastic parameters and relaxation modulus.

Key words: Burgers fitting, relaxation modulus, asphalt mortar, dynamic shear creep, viscoelastic parameters
