Next-Generation Wireless Bridge Weigh-in-Motion (WIM) System Integrated with Nondestructive Evaluation (NDE) Capability for Transportation Infrastructure Safety

The expansion in highway freight shipments has led to a substantial increase in truck traffic. The use of heavy vehicles (18 wheelers) has become the backbone of logistics and economic success, and national projections predict that freight shipments will double in the next ten years. Of particular concern are the increased number, size and weight of heavy commercial vehicles, some illegally overloaded. Overloaded vehicles can endanger the safety of transportation infrastructure and cause expensive premature structural damage. Bridge Weigh-in-Motion (WIM) is a method where an existing bridge is used as a weighing scale to identify the axles and gross weight of passing trucks. The system can provide information on overloading and potentially protect the bridge from sudden collapse. This project will develop rapidly deployable, portable wireless bridge WIM systems with enforcement and monitoring capability. Another unique system feature is the integration with state-of-the-art ultrasonic nondestructive evaluation (NDE) technologies that can assist in monitoring damage growth in critical structural members. The research will deliver a low-cost, easy-to-install-and-maintain, reliable monitoring system for long-term next-generation WIM and NDE deployment on bridges. By removing lengthy cables and bulky equipment, it is expected that an accurate, portable, and self-powered wireless WIM system incorporated with ultrasonic NDE will achieve much higher accuracy and reduce traditional cabled WIM system cost ($120k each) by at least 50%.
