This research study developed and quantitatively evaluated the concept of Bridge Weigh-In-Motion (B-WIM) and advanced knowledge within the field. The primary objective of B-WIM systems is to instrument a bridge to obtain the axle information (i.e., weights, number, speed, and spacings) and weight information (i.e., axles and gross) of trucks that cross the structure. A secondary objective of B-WIM is to evaluate the bridge itself. The challenge of B-WIM is to accurately obtain this information through robust sensing technology and post-processing algorithms. B-WIM (compared to pavement WIM) is potentially less disruptive to traffic, more durable, more economical, safer to install, and able to produce accurate truck-traffic data and bridge assessment information. This research study realized these advantages through the development of a B-WIM system that included extensive experimental testing followed by field validation on in-service bridges. A testbed bridge was utilized for preliminary B-WIM system development and testing before the deployment on in-service bridges. A load cell based B-WIM system was developed and quantitatively evaluated. Three in-service bridges were selected, and B-WIM systems for each bridge were developed and deployed. Data were collected and utilized for live load analysis and validation through an independent portable pavement WIM system. The systems on in-service bridges were able to accurately identify truck axle and weight information and the validation results were deemed satisfactory. Side-by-side challenge was investigated for both the load cell and strain gauge systems utilizing the distribution factors. In addition, an approach was developed to identify bridge parameters, such as distribution factors and composite action from B-WIM data. The final bridge evaluations included refined site-specific load ratings. Finally, guidelines for future B-WIM implementation were developed.
