Pressure Aging Vessel
The PAV is designed to simulate in-service aging of asphalt binders. The system exposes binder, aged in the RTFO to high pressure and temperature for 20 hours. During the aging period, the temperature and pressure are maintained at +/-0.3°C and +/-0.03 MPa, exceeding ASTM and AASHTO requirements. Control system fully automates start-up and shut-down and stores temperature and pressure test data for downloading to a PC. Pressure vessel is designed for operation at up to 150°C and 2.45Mpa. Unit comes with 10 stainless steel pans, air regulator with quick disconnect, handle for pan rack, spare O-ring and exhaust control.
