ROLLING THIN FILM OVEN (RTFO) – BAS-516
The Rolling Thin Film Oven (RTFO) is designed to evaluate the effect of heat and air on moving films of semi-solid asphalt binders. Complying with ASTM D2872 and AASHTO T240, the RTFO simulates short-term aging of asphalt binders for quality control and performance evaluation.
Standards:
- ASTM D2872
- AASHTO T240
Rolling Thin Film Oven (RTFO) for Asphalt Aging Testing
The Rolling Thin Film Oven (RTFO) is designed to determine the effects of heat and air on a moving thin film of semi-solid asphalt binder under controlled laboratory conditions.
The RTFO test simulates the short-term aging that occurs during asphalt mixing, transportation, and paving. After conditioning, the asphalt binder is evaluated by comparing its properties before and after the aging process.
The oven features a durable stainless steel chamber, a large glass inspection door, and is supplied with eight glass containers to ensure reliable and repeatable asphalt binder testing.

Rolling Thin Film Oven (RTFO) Test Method
The Rolling Thin Film Oven (RTFO) simulates the short-term aging of asphalt binders by exposing thin films of asphalt to controlled heat and airflow while continuously rotating glass containers.
This conditioning process reproduces the aging that occurs during asphalt production and paving, enabling engineers and laboratory personnel to evaluate changes in binder properties before and after aging.
Durable Oven Construction
The RTFO is manufactured with a robust stainless steel chamber that provides excellent temperature stability, uniform heat distribution, and long service life.
Its large glass viewing door allows operators to observe the testing process without interrupting the conditioning cycle, improving both safety and operational efficiency.
