The rolling thin film oven (RTFO) test is used to measure the effect of heat and air on a moving film of semisolid asphalt binder. The results of this treatment are determined from measurements of the binder properties before and after the test. The superpave PG binder specification looked for tests which would closely simulate field performance. Hotmix asphalt binder experiences significant aging during the manufacturing and laying process. Repeat ability of the test is directly related to the accuracy with which the oven temperature can be maintained and the re producibility of the thermal rise time of the system. Investigating this phenomenon within a laboratory environment, with a repeatable and simple test is very useful within the design process.
