WebThe Rolling Thin Film Oven Test (RTFOT ) is a conditioning process, rather than a test method and is described in EN 12607-1. RTFOT simulates the combined effects of heat and air on a thin film of bituminous binder. The procedure is intended to simulate the ageing that takes place during the mixing and transportation process for hot mixtures.
