- Abstract:
-
Anti-aging performanee of asphalt material is a key factor affecting the durability of asphalt pave.ment, simulating the aging test in laboratory is an important way to study the performanee of asphalt aging. lnorder to simulate the asphalt aging, rolling thin film oven testing, penetration testing, softening point test anddynamie shear rheometer test had been done and the test data is analyzed to diseuss how dillerent aging condilions affeet the performanee of asphalt and asphalt aging mechanism. The results show that the extension of thaging time, the improvement of asphalt aging temperature makes losses inerease, soltening point and penetration deerease, asphalt mixture fatigue resistance decline ; ageing time and temperature changes can dramatically change mobility of asphalt; when we inerease the shear rate, the rheologieal properlies of asphalt index deereased.
