Characterization of asphalt binders extracted from field mixtures containing RAP and/or RAS

The use of reclaimed asphalt pavement (RAP) and/or recycled shingles (RAS) in the mixtures is a common practice U.S.A. However, there controversy to date on how RAP/RAS interact with virgin binders (VABs) mixtures. For containing RAP/RAS, aged RAP and air-blown RAS alter performances extracted (EABs). Thus, rheological properties EABs from these require more investigation. focus this paper was relating high-temperature field cores corresponding rolling thin film oven (RTFO AVABs). Furthermore, comparison effect another objective. Different were collected within two weeks after construction process 2016. These represented eight different binder replacement percentages by RAP, RAS, or both. considered as RTFO AVABs. included temperature sweep frequency testing multiple stress creep recovery testing. had higher stiffnesses elasticates than AVABs because RAP/RAS. interacted readily VABs binders.
