Rolling Thin Film Oven he Rolling Thin-Film Oven (RTFO) procedure provides simulated short term aged asphalt binder for physical property testing. Asphalt binder is exposed to elevated temperatures to simulate manufacturing and placement aging. The RTFO also provides a quantitative measure of the volatiles lost during the aging process. The basic RTFO procedure takes unaged asphalt binder samples in cylindrical glass bottles and places these bottles in a rotating carriage within an oven. The carriage rotates within the oven while the 325°F (163°C) temperature ages the samples for 85 minutes. Samples are then stored for use in physical properties tests or the PAV. The standard Rolling Thin-Film Oven test is : AASHTO T 240 and ASTM D 2872. Effect of Heat and Air on a moving film of Asphalt (Rolling Thin-Film Oven Test) Asphalt binders typically lose volatiles during the manufacturing and placemen processes.
