Pressure Aging Vessels (PAV’s) use heated, pressurised air to simulate longterm oxidative aging of asphalt binders. The Pressure Aging Vessels (PAV's) consist of an ASME-Code and CE certified stainless steel pressure vessel, stainless steel cabinet with encased band heaters, and integral pressure measurement control.

This state of the art system meets ASTM, AASHTO, and EN 14769 requirements and includes a platinum RTD device to insure accurate temperature resolution and uniformity. A pressure relief valve and high-temperature thermal shut-down are included as standard safety features. A USB port located on the front of the unit allows the user to easily store test data and upgrade software if necessary. The system now includes remote operation capabilities, and allows the user to completely control the Pressure Aging Vessel (PAV) using an app compatible with most smart phones and tablets. The CRT-PAV Pressure Aging Vessel uses a Touch-Screen Controller with front panel user interface for complete control and monitoring of all test processes. The system has an operating pressure range of 2.1 ±0.1mPa, and temperature range of 80° to 115°C, with resolution of 0.1°C. 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 CRT-PAV includes a set of ten TFOT specimen pans, a precision anodised aluminum sample holder with lifting handle, and a specimen handling tool. Additional MOA-2 TFOT pans can be ordered as necessary. Bottled compressed air with a pressure of at least 325psi (2.24mPa) and a regulator must be user provided.
