Thin-Film Oven

The thin-film oven (TFO) test simulates short-term aging by heating a film of asphalt binder in an oven for 5 hours at 163° C (325° F). The effects of heat and air are determined from changes incurred in physical properties measured before and after the oven treatment by other test procedures.
