A premier global manufacturer with over 15 years of deep-seated civil engineering background, specializing in high-performance digital laboratory testing solutions.
Based within the high-tech industry development zone of the ancient historic city of Xi'an, China, Zealchon covers an expansive building area of 7,500 square meters. We stand at the forefront of researching, designing, manufacturing, and supplying high-precision testing instruments for civil engineering, geological survey, water conservancy, hydropower, road and bridges, highways, railways, and airport runways.
Our primary focus lies in the production and sales of advanced geotechnical testing instruments, asphalt and asphalt mixture testing machinery, alongside cement and concrete analysis systems. We integrate modern digital intelligence with mechanical reliability, delivering a qualitative array of research and laboratory testing equipment tailored to global criteria.
How advanced mechanical testing guarantees structural integrity in global asphalt paving projects.
In road paving, structural degradation from heavy wheel tracking, environmental fluctuations, and moisture infiltration can cause early rutting and cracking. The Digital Marshall Stability Tester measures the resistance to plastic flow of cylindrical specimens of bituminous paving mixtures. It determines the point of peak load (stability) and corresponding deformation (flow) under a standardized displacement rate of 50.8 mm/min.
Modern infrastructure demands digital precision. Transitioning from mechanical dial indicators to microprocessor-driven testers with S-type load cells and LVDT (Linear Variable Differential Transducer) sensors reduces user error and increases accuracy. The digital control unit registers stability values (in kN) and flow values (in mm) simultaneously, generating real-time load-deformation curves that help engineers analyze pavement performance before construction begins.
Measures up to 50kN / 100kN with an accuracy class of 0.05% FS, ensuring reliable test results under diverse compound pressures.
Integrated touch-control systems capture and graph deformation data in real-time, displaying structural failure points instantly.
Complies with international testing standards (ASTM D6927, AASHTO T245, EN 12697-34) to support multinational laboratories.
Deep technological heritage based on strategic alignment with China's leading civil engineering research institutes.
Zealchon's production facilities include comprehensive machining centers, CNC lathes, milling machines, planers, grinders, shearing machines, bending machines, electric welders, and argon arc welders. This array of equipment allows us to maintain tight tolerances and structural integrity during the manufacturing of high-load test frames.
The "Xiya" trademark was rated as a recognized trademark of Shaanxi Province, representing our engineering footprint and dedication to building premium-quality material testers.
Developed under the guidance of professors and researchers from Chang'an University Highway College, Air Force Engineering University, and Xi'an University of Technology.
Our R&D team has created testing equipment for asphalt, bridge decks, and geotechnical structures that fills gaps in the field, winning ministerial and provincial awards.
Used world-wide by government agencies, commercial testing laboratories, ready-mix concrete producers, infrastructure contractors, and universities.
Our technical support, marketing, and web development teams are based in China, providing comprehensive customer support, localized calibration help, and global after-sales services.
Our company monitors updates to national, ministerial, and industry testing standards, maintaining a production and sales service mechanism. Our products are widely used and trusted by research institutes and testing laboratories.
Zealchon adheres to a corporate spirit of being "people-oriented, cooperative, and pursuing excellence." We focus on quality first and honest operations, aiming to align our development with the technical requirements of our customers.
We provide high-quality testing instruments and support services. Our company offers "three guarantees" (repair, replacement, and refund) on all sold machinery, backed by technical support from our engineering team.
Addressing supply chain constraints, voltage standards, and regional verification systems.
When procuring a Digital Marshall Stability Tester on a wholesale scale, municipal departments and commercial laboratories face structural localization hurdles. Laboratories in North America require units that fully comply with ASTM D6927 (50.8 mm/min load rate and specific load rings) and operate on 110V AC 60Hz. Meanwhile, European highway authorities operate under EN 12697-34, which has different stability parameters, needing 220V AC 50Hz electrical configurations.
Zealchon addresses these demands by offering pre-calibrated multi-voltage systems with localized firmware available in several languages (including English, Spanish, Russian, and French). Our testing interfaces connect directly with standard Laboratory Information Management Systems (LIMS), enabling technicians to export test runs via USB or RS232 interfaces without manual entry errors. This level of localization helps verify that road materials meet domestic regulatory criteria.
The integration of IoT diagnostics, automated testing routines, and eco-efficient load systems.
As global sustainability goals change, the civil engineering industry is adjusting its material choices. The use of Reclaimed Asphalt Pavement (RAP), Warm Mix Asphalt (WMA), and polymer-modified binders is growing. These materials change how asphalt mixtures respond to loading, requiring testing instruments with higher sensitivity and adaptability.
Future digital stability systems will likely include automated load cell calibration, real-time cloud data sharing, and machine-learning assisted forecasting of pavement rutting behavior. By monitoring stress-strain trends across many test batches, laboratories can better predict the long-term durability of roads. Zealchon continues to update our instrumentation lines to support these technological transitions.
