The Thin Film Oven Test (RTFOT) is an experimental device used to simulate the aging process of asphalt under the action of heat and air. Through this Asphalt Rolling Thin Film Oven, the aging performance of asphalt caused by heat and oxidation during construction and use can be evaluated. 

Main features:

1. Simulated aging: Simulate the aging process of asphalt in actual use through heating and air flow.
2. Temperature control: Accurately control the temperature, usually 163 ° C, to ensure consistency in testing conditions.
3. Rotating design: By rotating the bottle, the asphalt forms a thin film, increasing the contact area with air and accelerating the aging process.
4. Automated operation: Some models have automatic control and data recording functions to reduce human errors.
