Asphalt Rolling Thin Film Oven ASTM D2872
This asphalt rolling thin film oven is designed and made as per ASTM D2872.
It is suitable to determine mass loss of petroleum asphalt thin film after being heated.
It is also used to determine performance changes of penetration, viscosity, ductility, and breaking point of asphalt residue after the thin film has been heated which can be used to evaluate anti-aging performance of asphalt.
I.Summary
This asphalt rolling thin film oven is designed and made as per ASTM D2872 . It 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.
II. Main technical features
1. This 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. It adopts high precise temperature controller which can meet test requirements.
