BALANCE THIN FILM OVEN

The Oven Fine Film Rolling Procedure (RTFO) offers short-term simulated asphalt ligant age for physical property testing. Asphalt binder is exposed to high temperatures to simulate the manufacture and placement of aging. RTFO also provides a quantitative measure of volatile compounds lost during the aging process. The basic RTFO procedure takes samples of asphalt binder without aging in cylindrical glass bottles and places these bottles in a car that rotates inside an oven. The cart rotates inside the oven while the 325 f (163 C) temperature ages of the samples for 85 minutes. Samples are stored for use in the properties of physical tests or APV. The standard oven thin film rolling test is: AASHTO T 240 and ASTM D 2872. Heat and air effect on a moving asphalt film (fine film rolling Oven Test)
 
Asphalt binders typically lose volatiles during manufacturing processes and placemen. The high temperature of these processes ages asphalt agglomerate by conduction was a substantial amount of volatile compounds. Field tests have shown that instead of asphalt binder it does not lose a significant amount of volatile compounds during its lifetime.
