Notes:
Recycled asphalt mixture is a multiphase system, which consists of sized recycled asphaltpavement (RAP), new asphalt, and/or recycling agents and new aggregates. RAP percentages mayhave influences on performance of total recycled asphalt mixture. The performance of asphalt mixtureis significantly affected by its dynamic response and fatigue performance (crack formation andpropagation). Dynamic and fatigue properties of virgin and recycled asphalt mixture are investigatedbased on Indirect Tensile Test (ITT). It is demonstrated in test results that recycled asphalt mixture isstiffer and more elastic-like than virgin ones with RAP added. The number of load cycles to fatiguefailure expected of recycled asphalt mixture is a bit decrease compared with that of virgin ones in lowstress level. In addition, high fatigue resistance of recycled asphalt mixture is observed in this testwhen stress level is high
