Abstract:The five skewed reinforced T-beam bridges listed below were tested during the summer of 2018 by the University of Maine (UMaine) in partnership with the Maine Department of Transportation (MaineDOT): (1) Bridge No. 5489 in Levant, carrying Route 222 over Black Stream; (2) Bridge No. 5109 in Hampden, carrying Route 9 over Souadabscook Stream; (3) Bridge No. 2390 in Unity, carrying Town Farm Road over Sandy; (4) Bridge No. 2879 in Atkinson, carrying Stagecoach Road over Piscataquis River; (5) Bridge No. 3848 in Columbia, carrying Saco Road over Western Little River. Revised load ratings were computed using data collected during live load testing. Details of bridge instrumentation, load cases, and strain plots for each bridge are provided in Appendices A.1 to A.6 inclusive. The results of the tests and analyses are summarized and are compared with the existing ratings. Use of these revised load ratings, live load test data, and extrapolation of these results to other structures is at the sole discretion of the bridge owner.
