Description

The Rolling Thin-Film Oven Test (RTFOT) is one of the most commonly used standardized tests to simulate the STA of binders. This test is used to measure the combined effects of heat and air on a thin film of bitumen or bituminous binder in permanent renewal.

Test Method

Determines the effect of heat and air on a moving film of asphalt to serve as an indicator of approximate change in properties during conventional hot-mixing. The results are reported in terms of the changes in selected properties such as viscosity, penetration, and ductility brought about by the RTFO test, as evidenced by test data taken before and after the 75-minute oven cycle.
