The aging of asphalt binders during service is affected by ambient temperature and other mixture-associated variables, such as component proportions in the mix, aggregate properties, and many more. Short-term aging (2 years or less) can be simulated in the laboratory by using a Rolling Thin Film Oven (RTFOT), while long-term aging (more than 7 years) can be simulated with a Pressure Aging Vessel (PAV).

Pressure Aging Vessel PAVThe Pressure Aging Vessel has been developed to simulate in-service aging of binders.
Rolling Thin Film Ovens (RTFOT)The Rolling Thin Film Ovens (RTFOT) is to simulate the short-term ageing of binders.
TFOT Bitumen OvenThe TFOT Bitumen Oven is used for determining the loss in mass of binders.
Vacuum Degassing Oven VDOThe Vacuum Degassing Oven VDO is designed to remove air bubbles created during PAV ageing.
