The ATS Pressure Aging Vessel (PAV3) simulates in-service oxidative aging of asphalt binder through exposure to elevated temperatures in a pressurized environment. Our PAV3 introduces a user friendly touchscreen and improved software, providing the highest level of efficiency and reliability during testing. Each PAV3 meets AASHTO R28, ASTM D6521, and EN 14769 test standards. ATS can also retrofit any previous version of our PAV and upgrade it to the PAV3.
