Automatic Asphalt Laboratory Equipment ASTM D2872 Rolling Thin Film Oven RTFOT
ASTM D2872 Rolling Thin Film Oven is suitable to determine mass loss of
highway asphalt rolling thin film after heating, and the change of penetration, viscosity,ductility and breaking
point of asphalt residue after the thin film has been heated, so as to estimate the aging performance of bitumen.
Features:
1. ASTM D2872 Rolling Thin Film Oven is composed of electric control component, working oven and
mechanical drive. An illuminating light is equipped in the oven for convenient observation.
2. There is an air compressor in the oven to supply the air needed for the test. The air can be controlled by a
flowmeter on the panel.
3. ASTM D2872 Rolling Thin Film Oven adopts high precise temperature controller which can meet test requirements.
