Answer #1

If bitumen is taken to rolling thin film oven test, it is tested for short age at high temperature. Viscosity of bitumen is increased due to loss of volatiles. After then if it is taken for ductility test , the ductility values is more than the ductility value of the fresh bitumen owing to the intact molecular structure of the fresh bitumen.
