Pressure Aging Vessel PAV

PAV Asphalt Pressure Aging Vessel HTHY-0630 is used to simulate the long-term aging process of asphalt under the action of climate and traffic load, to evaluate the anti-oxidative aging ability of different asphalt under certain test temperature and pressure conditions, and to provide aging asphalt samples for performance tests.

STANDARD

• ASTM D6521
• AASHTO R-28
• EN 14769

FEATURES
· 7-inch high-definition display controller, real-time monitoring of pressure and temperature in the chamber;
· Display the temperature-time and pressure-time curves in the chamber during the working process;
· Real-time display of the temperature error time and pressure error time of the aging process (to meet the requirements of the new specification);
· Temperature and pressure linkage control to ensure no overheating during pressurization;
· Record the data once every 5s, and export it as excel format data via U disk;
· After the test is completed, the process data can be automatically printed;
· Safety protection designs such as over-temperature, over-pressure protection, and high-pressure relief can effectively protect experimenters working under high-temperature and high-pressure experimental conditions;
· With overload protection, fault warning and other functions, there is a buzzer sound alarm prompt and display the fault code at the same time;
· The cabinet is made of stainless steel, treated with special technology, easy to clean and durable.
