Abstract Four hard-grade asphalt mixtures of two hard binders and two gradations are investigated in terms of their rutting resistance, cracking resistance, and moisture sensitivity. After examining the basic properties of the hard-grade asphalt mixture, its viscoelastic performance is given focus. The dynamic modulus test is executed at seven temperatures. Based on time temperature superposition, the sigmoid function of the viscoelastic models of the hard-grade asphalt mixture on is established, and the master curves of the dynamic moduli are also constructed. Results indicate that the hard-grade asphalt mixture has excellent resistance to rutting and that its low temperature performance and water sensitivity meet the current specifications. Research demonstrates that a dynamic modulus of coarse gradation is higher than that of fine gradation in the load frequency of 10^-3-10⁴ Hz. The viscoelastic analyses for the Christensen Anderson Marasteanu (CAM) model shows that the complex modulus of the glassy state G_e^*of coarse gradation is higher than that of fine gradation. The crossing frequency f_c in the CAM model of the fine gradation is higher than that of the coarse gradation. These results indicate that a finer gradation is beneficial to the low temperature performance of hard-grade asphalt mixture.
