Purpose:

GD-0610 RTFOT Rolling Thin Film Oven is designed and made as per T0610 “Asphalt Rolling Thin Film Heating Test” in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine mass loss of petroleum asphalt thin film after been heated. It can also be used to determine performance changes of penetration, viscosity, ductility, and breaking point of asphalt residue after the thin film has been heated to evaluate anti-aging performance of asphalt. It is also suitable to make determination as per ASTM D2872 “Test Methods for Effect of Heat and Air on a Moving Film of Asphalt (Rolling Thin-Film Oven Test)”.
