Status:  Complete
Report Date:  12/31/2015


Bridge maintenance treatments are expected to have an impact on remaining service life and bridge life-cycle costs. MnDOT is interested in learning about other transportation agencies practices to quantify the benefits of bridge maintenance treatments and how those treatments are incorporated into an agencys deterioration model. This Transportation Research Synthesis uses a literature review and a survey of domestic and international transportation agencies to gather information about the use of various bridge maintenance treatments, efforts to quantify the benefits of bridge maintenance treatments, and the use of deterioration models in examining the impact of bridge maintenance.
