Standard: EN 14769, ASTM D6521, AASHTO R28
Product Description
The NL PavePro Pressure Aging Vessel (PAV) simulates the long-term oxidative aging of asphalt binders caused by climate and traffic loading over a pavement's service life. By subjecting bitumen samples to controlled temperature and pressure, it evaluates the anti-oxidation capacity of different materials and provides aged specimens for essential performance testing.
Designed for standard laboratory benchtops, this compact unit features a high-definition touchscreen for real-time monitoring of aging cycles and error data. It integrates advanced safety protocols, including over-pressure relief and thermal protection, to ensure operator safety while meeting rigorous international standards.
Features of Pressure Aging Vessel (PAV)
- 7-inch HD Touchscreen Controller — Enables real-time monitoring of internal chamber pressure and temperature.
- Dynamic Data Visualization — Displays real-time temperature-time and pressure-time curves throughout the aging process.
- Compliance Monitoring — Provides real-time tracking of temperature and pressure deviation durations.
- Integrated Safety Interlocks — Features temperature and pressure linkage control to prevent overheating during the pressurization phase.
- High-Frequency Data Logging — Records data every 5 seconds; supports data export via USB in Excel format.
- Automated Reporting — Capable of automatically printing comprehensive process data upon test completion.
- Advanced Safety Protection — Equipped with over-temperature protection, over-pressure protection, and high-pressure relief systems to ensure operator safety during high-heat and high-pressure conditions.
- Intelligent Diagnostics — Includes overload protection and fault pre-warning systems with audible buzzers and digital error code displays.
- Premium Construction — The cabinet is constructed from high-grade stainless steel with specialized finishing for a professional aesthetic, ease of cleaning, and long-term durability.
