The effects of heat and air are determined by physical tests measured before and after the oven treatment.
A moving film of a sample is heated in an oven with a constant air flow and a vertical rotating shelf.

ASTM D 2872:
The samples are cooled down in horizontal position in a metal rack.
The change in sample mass (by analytical balance) and the changed properties of bitumen (by Ductility, Viscosity) are examined.

EN 12 607-1:
The samples are cooled down in a desiccator. The change in sample mass (by analytical balance) and the changed properties of binders (by Penetration, Softening-Point, Viscosity).
