Rolling Thin Film Oven
Rolling Thin Film Oven â Equipment for asphalt binder (bitumen) analysis
Asphalt binder is a thermoplastic material, which means its properties change significantly with temperature.
At high temperatures, asphalt binder becomes softer and may lose its load-bearing capacity, leading to deformations such as rutting, tire marks, and pavement depressions.
At high temperatures, asphalt binder becomes softer and may lose its load-bearing capacity, leading to deformations such as rutting, tire marks, and pavement depressions.
Therefore, tests such as softening point, penetration, and ductility allow us to predict how asphalt binder will behave under different climates and service conditions.

Rolling Thin Film Oven (RTFOT) (20-25720)
The Rolling Thin Film Oven (RTFOT) is equipment designed to evaluate the short-term aging of asphalt binders, simulating exposure to heat and air during the mixing and field compaction process. This test allows for determining how the properties of the asphalt binder vary under controlled laboratory conditions.
