A36 Bitumen rolling thin film oven (85 Type)
This method is applicable to measure evaporation losses of asphalt
materials, the residue of evaporation losses should do the needle
penetration test, calculating the ratio of residual penetration to
the original sample penetration, and measuring asphalt residue
ductility, softening point, and some other tests, to assess changes
in the nature of asphalt when heating.
