Protocol Worksheets for Data Collection
This study was conducted as part of the Federal Highway Administration’s Long-Term Bridge Performance (LTBP) Program. The LTBP Program is a long-term research effort, authorized by the U.S. Congress under SAFETEA-LU, the “Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users,” to collect high-quality bridge data from a representative sample of highway bridges nationwide that will help the bridge community to better understand bridge performance. The products from this program will be a suite of data-driven tools, including predictive and forecasting models that will enhance the ability of bridge owners to optimize their management of bridges.
In order to ensure that LTBP Program data are collected in a consistent manner over the duration of the program, data collection protocols are being developed for use by LTBP researchers. This report presents 51 protocols that will be used throughout the LTBP Program for data collection, mining of bridge legacy data, visual inspection, sampling and testing of concrete materials, and nondestructive evaluation of bridges, as well as data management and storage. Future versions will present additional protocols that will be implemented in the LTBP Program studies as well as any modifications deemed necessary to the 51 protocols herein. This report will be of interest to practitioners, researchers, and decision makers involved with the research, design, construction, inspection, maintenance, and management of bridges.

| 16. Abstract
The Long-Term Bridge Performance (LTBP) Program is a long-term research effort to collect scientific performance data from a representative sample of bridges in the United States. Data will be collected for in-service bridges using a variety of techniques. These data will be supplemented with legacy data from design plans, design and construction specifications, as-built plans and construction records, inspection and maintenance records, weather records, and traffic data. To maintain consistency in the manner in which data are collected and stored, a set of protocols has been developed. These protocols provide guidance on what kinds of information to obtain from existing bridge records and how each field testing activity is to be conducted; how to identify and classify the defects and how to measure their extent; and how to document the location and severity of the defect in the bridge element being evaluated. The protocols also specify the accuracy to which defect measurements are to be recorded. This report presents protocols for the collection and mining of legacy data, site preparation, visual inspection, sampling and testing of materials, nondestructive evaluation, and data storage and management. Future versions of this report will include additional protocols covering other activities, data collection methods, and analysis and reporting protocols for the LTBP Program. |
