PAV-1 Asphalt Pressure Aging System

Pressurized Aging VesselThe system design is based on the "Pressure Aging Vessel Accelerated Asphalt Aging Test Method (PAV)" proposed by China Petroleum&Chemical Corporation and drafted by the Heavy Oil Research Institute of the University of Petroleum (East China), as well as the ASTM D6521 and AASHTO PPI test methods. This system is a specialized equipment for evaluating the natural environmental aging status of asphalt.
