The Rolling Thin Film Oven (RTFO) test is used to measure the effect of heat and air on a moving film of semi-solid asphalt binder. The results of this treatment are determined from measurements of the binder properties before and after the test.
Repeatability of the test is directly related to the accuracy with which the oven temperature can be maintained and the reproducibility of the thermal rise time of the system. The invention of RTFO by James Cox & Sons led to the present day AASHTO, ASTM and EN standards for Rolling Thin Film Oven test (RTFOT).

Applied Test Systems has been manufacturing custom furnaces and ovens since 1965, and entered into the bitumen / asphalt binder market in the early 1990’s with the introduction of Superpave! It only seems logical to expand our many years of industry and process heating knowledge into the creation of the Applied Test Systems Rolling Thin Film Oven, the RTFO Touch.
The NEW RTFO Touch from ATS has been designed to simulate short-term aging of asphalt binder according to ASTM D2872, AASHTO T240, EN 12607, Superpave, and California Test Method 346 test standards and now offers customizable options to accommodate a broad spectrum of users.
