Bitumen and Asphalt Testing Equipment - Rolling Thin Film Oven

Rolling Thin Film Oven

Rolling Thin Film Oven TT-2872

Rolling Thin Film Oven TT-2872 is crafted to meet the specifications outlined in the ASTM D2872 Standard Test Method for Effect of Heat and Air on a Moving Film of Asphalt (Rolling Thin-Film Oven Test). 

This oven serves to approximate the changes in asphalt properties during conventional hot-mixing at approximately 302℉ (150℃), as indicated by viscosity and other rheological measurements. It produces a residue that closely resembles the asphalt's condition when integrated into pavement. Significant deviations in mixing temperature from the 302℉ (150℃) level may lead to varying effects on properties. Additionally, this test method facilitates the determination of mass change, offering insights into asphalt volatility.
