    Rolling Thin Film Ovens

    Made from high-quality stainless steel, the Rolling Thin Film Oven is available in two models and is ideal for determining the specific performance variation of semisolid bitumen when under experimental conditions. The triple-wall interior jacket heating system with internal elements is excellent for achieving temperature uniformity and mimicking real-life processes.

    Frequently Asked Questions 

    what is a rolling thin film oven used for?

    A rolling thin film oven is used primarily in the asphalt industry to simulate the short-term aging of asphalt binder. A thin film of asphalt binder is heated in a rotating container at a specific temperature for a specific amount of time. This mimics the real-world conditions it would undergo during hot asphalt mixing and road laying.

    What is the rolling thin film oven test for bitumen?

    The Rolling Thin Film Oven Test (RTFOT) assesses the short-term aging effects of heat and air on asphalt binders. The oven simulates the conditions asphalt undergoes during mixing and laying. This helps predict the changes in viscosity consistency and other properties critical to good asphalt performance.

    What temperature is the Rtfo test?

    The RTFOT test is conducted at 163 C. This simulates consistent conditions to simulate the short-term aging effects of heat and air.
