Name：Asphalt rotating film oven
Model：YZ-85
Specification
This product is suitable for measuring road petroleum asphalt, the influence of rotating film oven heating (RTFOT) on viscous asphalt, the mass loss after heating, and the penetration, viscosity, and ductility of asphalt residue after heating of rotating film as needed. To evaluate the aging performance of asphalt, it is based on TB/T5502-91 “Technical Conditions of Drying Box” and T0609-93, T0610-93. Explosive items are strictly prohibited to be heated in the box to avoid danger.
