Develop Bridge Weigh-in-Motion Approach to Measure Live Loads on Texas Highways
The primary objective for bridge weigh-in-motion (B-WIM) systems is to characterize the truck loading on a given corridor. B-WIM (compared to pavement weigh-in-motion) is potentially less disruptive to traffic, more durable, more economical, safer to install and able to produce accurate traffic data. This project aims to realize these potential advantages through the development of a B-WIM system that includes extensive experimental testing. The system will identify the truck gross weight, axles (weights, number and spacing), speed and vehicle classification. A secondary objective of B-WIM is to evaluate the bridge itself. The research team will develop an approach to identify bridge parameters such as distribution factors, percent composite action, dynamic impact factor, and stress cycles from B-WIM data. The Performing Agency will include site-specific load ratings on the final bridge evaluations. The overall purpose of B-WIM is to aid the Texas Department of Transportation (TxDOT) with future decisions. The major technical objectives of this research are to: (1) Develop and finalize the B-WIM approach through preliminary experimental testing. (2) Select three (3) bridges to install B-WIM systems along crucial corridors. (3) Install the B-WIM system along three in-service bridges, which includes calibration of each setup. (4) Conduct traffic data analysis and a validation study. (5) Perform an evaluation of each in-service bridge.
