Pressure Aging Vessel (PAV's) uses heated, pressurized air to simulate long-term oxidative aging of asphalt binders. The PAV oven consists of an ASMECode stainless steel pressure vessel, in a stainless steel cabinet with encased band heaters.
This state of the art system meets all ASTM and AASHTO requirements and include a platinum RTD device to insure accurate temperature values to ±0.1°C. Pressure relief valves and high-temperature thermal shut down controls are included as standard safety features.
The Pressure Aging Vessel uses a Programmable Logic Controller (PLC) for complete control and monitoring of all test processes. This easy to use system completes a test in three easy steps; press the heat button, insert specimens when prompted, and press the age button. The ATS PAV includes a set of ten TFOT specimen pans, a sample holder with lifting handle, and a specimen handling tool.
Bottled compressed air with a pressure of at least 325 psi (2.24 MPa) and a regulator must be user provided.
