Aging (PAV, VDO, RTFO, TFO)

Pressure Ageing Vessel PAV and Vacuum Degassing Oven VDO

The ageing 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 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 PAV

The Pressure Aging Vessel has been developed to simulate in-service aging of binders.

Updated

Rolling Thin Film Ovens (RTFO)

To simulate the short-term ageing of binders.

TFOT Bitumen Oven

Used for determining the loss in mass of binders.

Vacuum Degassing Oven VDO

VDO is designed to remove air bubbles created during PAV ageing.
