The PAV Pressure Aging Vessel complies with relevant industry standards and is designed to simulate the long-term aging process of asphalt binders under climatic conditions and traffic loading. By accelerating oxidative aging under specified temperature and pressure conditions, the PAV evaluates the long-term aging performance of asphalt binders and provides aged binder specimens for further performancetesting.
