The Falling Weight Deflectometer (FWD) represents the gold standard in non-destructive testing (NDT) for pavement structural evaluation. Unlike static loading methods, FWD technology simulates the dynamic load of a moving vehicle, providing a more accurate assessment of how pavement layers—from the surface asphalt to the deep subgrade—react under real-world traffic conditions. As a leading Custom FWD Falling Weight Deflectometer Supplier, Xi'an Zealchon Electronic Technology Co., Ltd. provides high-precision instruments that allow engineers to calculate the Resilient Modulus and identify structural deficiencies before they manifest as surface failures.
Our FWD systems are designed to bridge the gap between complex laboratory geotechnical analysis and in-situ rapid field testing. By delivering "Information Gain" through multi-sensor data fusion, our equipment helps road authorities and contractors optimize maintenance budgets and extend the lifecycle of critical infrastructure.
Focus on the accuracy of the impulse load and the synchronization of deflection sensors (geophones). Ensuring compliance with AASHTO T 256 and ASTM D4694.
Integration of GPS, thermal imaging, and high-speed data processing units to allow for rapid testing cycles (under 30 seconds per point) without sacrificing data fidelity.
The future involves "Digital Twin" integration. AI algorithms analyze deflection basins to automatically predict remaining fatigue life and subgrade stability in real-time.
Heavy-duty FWD configurations capable of simulating aircraft loading (HWD) to ensure the structural integrity of runways and taxiways.
Testing the modulus of the graded gravel and sub-ballast layers to prevent differential settlement in ballastless tracks.
Trailer-mounted or vehicle-integrated FWD solutions for rapid assessment of municipal road networks with minimal traffic disruption.
Specialized instruments for universities (like Chang'an University) to study advanced pavement materials and structural mechanics.
Located in the ancient yet high-tech hub of Xi'an, Zealchon’s 7,500 square meter facility is a testament to Manufacturing Excellence. Our production workshop is equipped with state-of-the-art CNC lathes, milling machines, and precision welding centers (Argon arc). This vertical integration allows us to maintain a competitive FWD Falling Weight Deflectometer Pricelist while ensuring every component meets rigorous quality standards.
When selecting an FWD supplier, global enterprises must look beyond the initial price. Our systems are engineered to meet international Local Support and Compliance standards. We provide comprehensive documentation for CE certification and ensure that our software interfaces seamlessly with international Pavement Management Systems (PMS).
Dedicated teams in China provide 24/7 remote assistance and localized calibration protocols.
Our "Three Guarantees" promise ensures every machine delivered is calibrated against reference standards.
Our supply chain is built to withstand global logistical challenges, ensuring timely delivery of parts and whole units.
Our FWD geophones offer a resolution of 0.1 microns with an accuracy better than ±2%. This precision is vital for the dynamic backcalculation of layer moduli.
Our systems include integrated infrared surface temperature sensors and deep-probe thermometers to provide the necessary data for temperature correction of asphalt stiffness.
Yes. We offer custom configurations from 12kN for light pavements to 250kN for heavy-duty airfield applications (HWD).
We provide a proprietary data acquisition and analysis suite that supports various backcalculation models (e.g., EVERCALC, MODULUS) and exports to standard GIS formats.
