Asphalt Rolling Thin Film Oven (85 Type)

This instrument is designed and made as per industrial standard T 0610-2011 and ASTM D2872 Standard Test Method for Effect of Heat and Air on a Moving Film of Asphalt in JTG E20-2011 Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering.  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.

I.  Main technical features

1.  This 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.  The intelligent temperature control instrument ensures that the oven temperature reaches 163℃±0.5℃ within 10 minutes after the sample is installed, which meets the requirements of the test regulations.
