The global road maintenance market is undergoing a seismic shift towards sustainable, thin-layer surfacing technologies. As governments strive to reduce carbon footprints and extend pavement lifecycles, Slurry Seal and Micro-surfacing have emerged as critical solutions. However, the efficacy of these treatments depends entirely on the design of the mix and its resistance to wear under traffic and moisture.
The Asphalt Wet Wheel Abrasion Loss Tester (WWAT) is the cornerstone of this quality assurance. It measures the minimum binder content required to prevent aggregate loss in the presence of water—a failure mode that can lead to rapid road deterioration and safety hazards. From the high-speed expressways of North America to the heavy-load corridors of Asia, the WWAT ensures that emulsified asphalt mixtures can withstand the harshest environmental stresses.

Modern testers now incorporate high-torque motors with variable speed control, ensuring consistent abrasion rates that strictly adhere to ISSA TB-100 and ASTM D3910 standards. The integration of high-grade stainless steel components ensures longevity even in corrosive laboratory environments.
The future of bitumen testing lies in data. Our latest OEM models feature touchscreen interfaces, automated weighing calculations, and IoT connectivity, allowing lab managers to track test progress and export data directly to cloud-based quality management systems.
As the industry moves toward "Green Bitumen," testing equipment must adapt to new chemical additives and bio-based emulsions. Our machines are calibrated to handle a wide range of modified binders, providing accurate abrasion loss data for next-generation eco-friendly road materials.

The "Xiya" trademark was rated as a trademark of Shaanxi Province. 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.
The production workshop has production equipment such as machining center, CNC lathe, milling machine, planer, grinder, shearing machine, bending machine, electric welder, argon arc welder, etc.
Our machines are used world-wide by government agencies, commercial testing laboratories, ready mix producers, contractors and universities. Over 15 years of quality dedication.
High-friction micro-surfacing on runways requires extremely low abrasion loss. Our WWAT equipment provides the precise data needed to ensure flights land safely on durable surfaces.
In hot climates, bitumen emulsion can become brittle. Testing with the Wet Wheel Abrasion method helps engineers optimize mix designs to prevent premature aggregate stripping.
Cost-effective slurry seals are vital for rural networks. Our portable and reliable testers allow local government labs to maintain quality without massive infrastructure investment.
The company keeps up with the pace of national standards, ministerial standards, and industry standards testing, and has a production and sales service mechanism. The products are deeply trusted by user units.
Adheres to the corporate spirit of "people-oriented, unity and cooperation, pursuit of excellence", and the purpose of "quality first, honesty and trustworthiness".
Quickly grows into a technology-based professional enterprise, providing the market with high-quality products. We promise to provide three guarantees for all products sold.
The primary purpose is to determine the minimum binder content for a slurry seal or micro-surfacing mixture. It ensures that there is enough emulsified asphalt to bond the aggregates together effectively under wet conditions, preventing material loss under traffic.
Yes, we specialize in OEM solutions. While our standard machines follow ISSA TB-100 and ASTM D3910, we can customize motor speeds, abrasion head weights, and digital interfaces to meet specific regional requirements or proprietary testing protocols.
Generally, a lower abrasion loss value indicates better performance. For micro-surfacing, the maximum loss is typically specified (e.g., 538 g/m² for a 1-hour soak). If loss exceeds this, the binder content may need to be increased or the aggregate quality improved.
Regular calibration of the motor speed and inspection of the rubber hose (abrasion head) are crucial. Since the test involves water, ensuring that the drainage and stainless steel components are cleaned after each use will extend the machine's life significantly.
