Pressure Aging Vessel

Asphalt Pressure Aging Vessel (PAV) 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.

STANDARDS COMPLIANCE :

• COMPLIED AS PER AASHTO R28, ASTM D6521, EN 14769

Design / Construction :

• The lightweight structure of the equipment fits perfectly on any standard laboratory benchtop and is easy to operate and maintain.
• The cabinet is made of stainless steel, treated with special technology, easy to clean and durable.

Operation and Control :

• 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.

Data Recording and Output :

• 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 Features :

• 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.
