Abstract:
Anti-aging performanee of asphalt material is a key factor afecting 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, solening point test anadynamie shear rheometer test had been done and the test data is analyzed to diseuss how dillerent aging conditions alleet the perormanee of asphalt and asphalt aging mechanism. The results show that the extension of theaging lime, the improvement of asphalt aging temperature makes losses inerease, solening point and penetralion deerease , asphalt mixture fatigue resistanee deeline ; ageing lime and temperature changes can dramatieally change mobility of asphalt; when we inerease the shear rate, the rheologieal properties of asphalt index de.creased.
