Quantifying the Impact of Bridge Maintenance Activities on Deterioration: A Survey of Practice and Related Resources

Minnesota Department of Transportation (MnDOT) is interested in learning about practices to quantify the benefits of various bridge maintenance treatments in relation to remaining service life and bridge life-cycle costs. In addition, the agency is interested in knowing how maintenance treatments may be incorporated into deterioration models. To support this effort, CTC & Associates conducted a literature search and a survey of domestic and international transportation agencies to learn about the type and frequency of bridge maintenance activities, practices for quantifying the impact of bridge maintenance activities on deterioration, and the use of deterioration models to examine the benefits of bridge maintenance. This document includes a summary of findings from the online survey, related documents, the full text survey responses, and three of the related documents in full in the appendices.
