Abstract:
To evaluate the deformation resistance of coal direct liquefaction residue(DCLR)modified asphalt mixture and compound DCLR modified asphalt mixture under high temperature and heavy load, the tri-axial repeated load test was carried out on two asphalt mixtures with the gradation of AC-20 under multi-temperatures(50 ℃, 60 ℃, 70 ℃)and multi-loads(0.7, 0.8, 0.9, 1.0 MPa)conditions, and the test data were nonlinearly fitted. An index for evaluating the deformation resistances of the two asphalt mixtures under high temperature and heavy load was proposed, and the variance analysis method was used to investigate the significant influences of temperature and load on the deformation resistance of asphalt mixture. Research result shows that the permanent deformations of two asphalt mixtures increase as temperature and load increase. The flow number and nonlinear fitting index have negative and positive correlation with temperature and load, respectively, indicating that both nonlinear fitting index and flow number can reflect the deformation resistance of asphalt mixture. However, the flow number three-dimensional surfaces of the two asphalt mixtures have intersects when temperature varies from 65 ℃ to 70 ℃ and load is 1.0 MPa, demonstrating that flow number cannot effectively distinguish the deformation resistances of DCLR modified asphalt mixture and compound DCLR modified asphalt mixture under high temperature and heavy load. The sensitivity of two asphalt mixtures to temperature is higher than to load at a significant level of 0.05. Therefore, temperature is the main factor that affects the deformation resistances of the two asphalt mixtures, and load is the secondary factor. The nonlinear fitting index and flow number of temperature and load have significant influences on the deformation resistances of two asphalt mixtures when the significant levels are 0.013 and 0.113, respectively, reporting that the nonlinear fitting index is more suitable than the flow number for evaluating the deformation resistances of DCLR modified asphalt mixture and compound DCLR modified asphalt mixture within test temperature and load conditions. 3 tabs, 7 figs, 32 refs.
