PRESSURE AGEING VESSEL - ASTM D6521-13

The Pressure Aging Vessel (PAV) provides simulated long term aged asphalt binder for physical property testing. Asphalt binder is exposed to heat and pressure to simulate in-service aging over a 7 to 10 year period. The basic PAV procedure takes RTFO aged asphalt binder samples, places them in stainless steel pans and then ages them for 20 hours in a heated vessel pressurized to 305 psi (2.10 MPa or 20.7 atmospheres). Samples are then stored for use in physical property tests. Vacuum Degassing Oven (VDO) & Dynamic Shear Rheometer (DSR) are available at extra cost.
