Abstract:
In order to explore the feasibility and optimal replacement amount of coal gangue powder instead of mineral powder, the road performance of asphalt mixture AC-16 was analyzed by using different substitution proportions of coal gangue powder instead of mineral powder. The high temperature stability, low temperature crack resistance and water stability of AC-16 asphalt mixture with different substitution proportions of coal gangue powder were evaluated by rutting test, low temperature beam bending test, immersion Marshall residual stability test, and freeze-thaw splitting strength test. The shear strength was analyzed by triaxial test, and the fatigue performance was analyzed by three-point bending method. The microstructure of coal gangue powder and mineral powder was compared by SEM and Image-Pro Plus, to reveal the influence mechanism of coal gangue powder on asphalt mortar. The results show that the high-temperature stability, low-temperature performance and water stability of substitution proportion(mass fraction, the same below)40% coal gangue powder asphalt mixture meet the specification requirements, and its dynamic stability can reach 2 472 times/mm, and the shear strength and fatigue resistance are the best, and its bonding force C and internal friction angle φ are 0.128 MPa and 38.5°, respectively. Compared with mineral powder, coal gangue powder has large specific surface area, low strength and high needle flake content, which can significantly improve the road performance of asphalt mixture under certain dosage.7 tabs, 12 figs, 21 refs.
