What Is a Thin Film Bitumen Oven?
The Thin Film Bitumen Oven evaluates the effect of heat and air on asphalt and bituminous binders. It can also be used to determine mass loss caused by heating. Therefore, laboratories can assess how bituminous materials change after controlled thermal exposure.
During testing, specimens are exposed to controlled temperature and air circulation. A rotating platform moves the samples continuously inside the chamber. This arrangement helps create uniform and repeatable testing conditions.
The LT-AS0041 Thin Film Bitumen (Loss on Heating) Oven operates from room temperature up to 200 °C and has a 120 litre chamber.
Precise Temperature Control
A digital PID controller continuously regulates the oven temperature. The operator sets the required temperature according to the applicable test procedure.
Stable temperature control helps reduce variations between consecutive tests. In addition, the system includes audible and visual alarms for over-temperature conditions. This provides an additional level of operational safety during laboratory testing.
Rotating Test Platform
The oven contains a motor-driven rotating platform operating at approximately 5–6 rpm. Continuous rotation exposes the specimens more evenly to heated air.
Two different rotating shelves are available. The LT-AS0041/1 Ø250 mm shelf supports loss-on-heating applications, while the LT-AS0041/2 Ø342 mm shelf is intended for thin-film oven testing.
Forced Air Circulation
An integrated circulation fan continuously moves hot air throughout the chamber. Ventilation openings also support controlled airflow inside the oven.
Uniform air circulation helps minimise temperature differences between different areas of the chamber. Therefore, specimens can experience more consistent heating conditions throughout the test.
Durable 120 Litre Chamber
The internal chamber has a capacity of approximately 120 litres and is manufactured from 304-grade stainless steel. This construction provides resistance to routine laboratory use and simplifies cleaning.
The external cabinet is manufactured from electrostatic powder-coated sheet steel. A double-layer tempered glass front door allows the operator to observe specimens without opening the chamber.
Sample Containers and Accessories
The oven can be supplied with different specimen containers according to the selected method.
The LT-G0152 Moisture Content Tin measures Ø55 × 35 mm and is supplied in packs of nine. The larger LT-G0157 container measures Ø140 × 9.5 mm and is supplied in packs of four.
Testing According to International Standards
The Thin Film Bitumen Oven supports laboratory procedures associated with EN 12607-2, EN 13303, ASTM D6, ASTM D1754, AASHTO T47 and AASHTO T179. Liya Test lists these standards for the LT-AS0041 product.
Overall, the LT-AS0041 Thin Film Bitumen (Loss on Heating) Oven combines precise temperature control, forced air circulation and controlled specimen rotation. Therefore, asphalt producers, universities and quality control laboratories can perform bitumen ageing and loss-on-heating procedures under consistent laboratory conditions.
