The TBTPAV-II bitumen PAV system consists of the TBTPAV-I Pressure Aging Vessel (PAV) and the TBTPAV-II Vacuum Degassing Oven (VDO).
The pressure aging vessel simulates the accelerated aging process of asphalt binders in service on roads by using high pressure and temperature.
The vacuum degassing oven removes air bubbles created during the in-service oxidative aging of asphalt binder. The aging process begins with the binder being first aged using T 240 (RTFOT, where TBT-0610W is the suitable model). A specified thickness of residue from the RTFOT is then placed in stainless steel pans and aged at the designated aging temperature for 20 hours in a vessel pressurized with air to 2.10 MPa. The selected aging temperature depends on the grade of the asphalt binder. Following the completion of the PAV process, the asphalt binder residue is then vacuum degassed.
The TBTPAV-II system is certified under the ISO 9001 quality management system for safety supervision.
