Abstract:

To analyze the influence of the content of aggregate on the mechanical properties of asphalt mixture， four grades of asphalt mixtures are prepared by Superpave gyratory compactor. The cracking resistance， compression resistance， and creep properties of the four asphalt mixtures are respectively studied by splitting tests， compression tests， and creep tests at different temperatures. Then， the variations of relaxation moduli of four grades of asphalt mixtures with the loading time are deduced by convolution integral and Laplace transform， and the creep and relaxation characteristics of four grades of asphalt mixtures are fitted and analyzed by Burgers model and second-order extensive Maxwell model. Finally， according to the grey correlation degree algorithm， the correlation degree between aggregate content and mechanical properties of asphalt mixtures is calculated， and the influence of aggregate content on the mechanical properties of asphalt mixtures is analyzed. The results show that the low-temperature cracking resistance， room temperature tensile and compressive properties of asphalt mixtures are highly related to the content of aggregate with 0.15~0.3 mm and 1.18~2.36 mm， while the creep resistance at room temperature is mainly affected by aggregate with 0.6~1.18 mm and 2.36~4.75 mm. As the temperature increases， the effect of aggregate content on the creep resistance increases. The relaxation strength is greatly affected by the fine aggregate， while the relaxation time is mainly affected by the larger aggregate.
