ATS Pressure Aging Vessel Asphalt Binding Testing

Burhani Engineering Technology: Pressure Aging Vessel (PAV4) The Pressure Aging Vessel (PAV4), manufactured by Burhani Engineering Technology, is a high-precision laboratory instrument designed to simulate the long-term oxidative aging of asphalt binders. This equipment is essential for road construction research and quality control, replicating approximately 7 to 10 years of environmental exposure in a compressed 20-hour timeframe. By subjecting binders to extreme pressure and heat, the PAV4 allows engineers to evaluate how asphalt will perform against fatigue and thermal cracking over its actual service life.

Technical Design and Innovation

The Burhani Engineering PAV4 features a compact, benchtop design with an integrated vessel and oven system. Built for durability and ease of use, it incorporates several advanced technical elements:
Touchscreen Interface: Equipped with an industrial-strength touchscreen and intuitive software, the unit provides real-time monitoring of critical parameters including time, temperature, and pressure.
Precision Performance: Using a platinum RTD sensor, the system maintains a temperature accuracy of. It also boasts an industry-leading recovery time of 30 minutes or less, significantly increasing laboratory throughput.

Connectivity: A front-mounted USB port allows for seamless data acquisition and software upgrades.
