Bitumen PAV System (PAV & VDO) Manufacturer

TBTPAV-II Bitumen PAV System consists of TBTPAV-I Pressure Aging Vessel(PAV) & TBTPAV-II Vacuum Degassing Oven(VDO).

TBTPAV-I Pressure Aging Vessel(PAV) simulates the accelerated aging process of asphalt binders in service on road by high pressure and temperature.

TBTPAV-II Vacuum Degassing Oven(VDO) removes air bubbles created during the in-service oxidative ageing of asphalt binder.

The method is first aged using T 240(RTFOT, TBT-0610W is suitable model). A specified thickness of residue, from the RTFOT, is then placed in stainless steel pans and aged at the specified aging temperature for 20h in a vessel pressurized with air to 2.10 MPa. The aging temperature is selected according to the grade of the asphalt binder. At the completion of the PAV process, the asphalt binder residue is then vacuum degassed.

TBTPAV-II system is certified by Regulations of Safety Supervision of ISO 9001 quality management system.
