This asphalt film heating oven is suitable for measuring the quality changes of road petroleum asphalt and polymer-modified asphalt films after heating. As needed, it can also measure changes in properties such as penetration, ductility, softening point, and viscosity of the residue after film heating to evaluate the aging resistance of asphalt.
