In the realm of pavement engineering, the longevity of asphalt binders is a primary concern for contractors, government agencies, and research institutions. The Bitumen Pressure Aging Tester (PAV) stands as the industry gold standard for simulating the long-term oxidative aging that occurs in asphalt binders during 7 to 10 years of service life. As a leading OEM Bitumen Pressure Aging Tester Manufacturer, we recognize that the precision of these instruments directly influences the reliability of infrastructure life-cycle predictions.
Operating at 2.10 MPa and temperatures between 90°C to 110°C, our PAV systems provide the strictly controlled environment required by ASTM D6521 and EN 14769 standards.
Our latest models integrate digital data logging, allowing for real-time monitoring of pressure and temperature gradients to ensure zero-deviation testing cycles.
Engineered with stainless steel pressure vessels and redundant safety valves, our equipment ensures operator safety in high-pressure environments.
Global infrastructure is currently facing unprecedented challenges due to extreme temperature fluctuations. This has led to a surge in demand for high-performance bitumen binders. Laboratory testing is no longer a luxury but a prerequisite. Procurement officers in North America, Europe, and Asia are increasingly looking for Pricelist transparency and OEM customization to fit specific laboratory workflows.
"Information Gain: Modern PAV testing is now being combined with Dynamic Shear Rheometer (DSR) analysis to create a comprehensive 'Aging Profile' of bitumen, significantly improving road durability."
China has become the global hub for civil engineering instrumentation. Factories in Xi’an, like Zealchon, benefit from an integrated supply chain that combines advanced metallurgy with sophisticated electronic control systems. This allows us to offer competitive pricelists without compromising on the strict tolerances required by international testing protocols.
In the United States and Canada, PAV testing is mandatory for determining the Performance Grade (PG) of asphalt binders. Our OEM testers provide the stability needed for long 20-hour aging cycles.
In China and Europe, the bitumen used in railway waterproofing and vibration damping must undergo rigorous PAV aging to ensure it maintains elasticity over decades.
Airports require bitumen binders that resist the heavy loading of aircraft. Our PAV solutions help engineers select the right polymer-modified bitumen (PMB) for these high-stress environments.
With more than 15 years of civil engineering background, located in the new technology industry development zone in Xi'an, an ancient city in China. It covers an area of 7500 square meters of building area.
We manufacture and supply testing instruments for civil engineering, geological survey, water conservancy and hydropower, roads and bridges, highways, railways, and airports. We specialize in the production and sales of geotechnical testing instruments, asphalt and asphalt mixture testing instruments, cement and concrete testing instruments.
Under the guidance and cooperation of many professors and researchers from Chang'an University Highway College, Air Force Engineering University, and Xi'an University of Technology, we introduced technology to develop a series of professional and core technology testing instruments.
Our production workshop has production equipment such as machining centers, CNC lathes, milling machines, and argon arc welders, ensuring every Pressure Aging Vessel is machined to micron-level precision.
The "Xiya" trademark is rated as a prestigious trademark of Shaanxi Province. We have filled gaps in the domestic market with instruments that won national and ministerial awards.
Our machines are used worldwide by government agencies, commercial testing laboratories, ready-mix producers, and prestigious universities.
A: According to ASTM D6521, the standard aging process typically takes 20 hours at a specified temperature (90°C, 100°C, or 110°C) and a pressure of 2.10 MPa.
A: OEM partnerships allow for localized branding, customized software interfaces in various languages, and hardware modifications to meet specific national safety regulations while maintaining a competitive pricelist.
A: Regular calibration of temperature sensors and pressure gauges is vital. The seal on the pressure vessel should also be inspected every 50 cycles to ensure airtight operation.
A: Yes, our Pressure Aging Testers are specifically designed to handle the complex aging characteristics of both neat bitumen and PMB.
