Industry-leading solutions for asphalt, bitumen, and pavement analysis.
The Evolving Science of Bituminous Material Stability Testing
In the modern era of civil engineering, the durability of asphalt road surfaces is non-negotiable. The **Asphalt Flotation Stability Tester** (Floating Test) is a critical instrument defined by **ASTM D139**, used to evaluate the consistency and temperature susceptibility of bituminous binders. As global urbanization accelerates, especially in Southeast Asia and Africa, the demand for precise, repeatable testing equipment has surged by 18% annually.
Modern testers have transitioned from manual observations to **Automatic Digital Display** systems. High-precision sensors now provide a resolution of 0.1°C and timing accuracy within milliseconds. This technical leap ensures that engineers can accurately predict the behavior of asphalt under extreme climatic conditions—be it the scorching heat of the Middle East or the freezing tundras of Northern Europe.
China, led by innovation hubs like Xi'an, has become the global nerve center for testing instrumentation. The advantage lies in the integration of massive industrial supply chains with academic research. Xi'an Zealchon, for instance, leverages the intellectual capital of **Chang'an University**, allowing for rapid prototyping and higher cost-efficiency than traditional European manufacturers.
With more than 15 years of civil engineering background, located in the new technology industry development zone in Xi'an, we cover an area of 7500 square meters. We specialize in the production and sales of geotechnical testing instruments, asphalt and asphalt mixture testing instruments, and cement and concrete equipment.
Our research team, founded by experts from Chang'an University and Xi'an Polytechnic University, represents the pinnacle of geotechnical technology. The "Xiya" trademark is not just a brand; it’s a standard of quality in Shaanxi Province and across the global market.
In high-speed rail construction, asphalt layers must maintain extreme stability under dynamic loading. Flotation testing ensures the binder meets the rigid shear resistance required for 350km/h track systems.
Municipalities use our testers to determine the aging rate of existing asphalt, allowing for data-driven decisions on whether to resurface or perform localized repairs.
The industry trend is shifting toward crumb rubber and bio-binders. Our testers are being recalibrated to handle these complex, non-Newtonian fluids, providing "Information Gain" for sustainable material R&D.
Advanced equipment: Machining centers, CNC lathes, argon arc welding, and more.
