Reusability and Impact Damage Repair of Twenty-Year-Old AASHTO Type III Girders
The report describes the results of a four girder test series used to evaluate impact damage and effectiveness of repairs. The girders used for the study were fabricated in 1967 and placed into service. The girders were removed from service in 1984 as a result of a road realignment project. The objectives of the research project were to: (1) determine the effective prestress in the strands after 20 years; (2) determine the influence of impact damage on girder performance; (3) evaluate the performance of two impact damage repair schemes under static, fatigue and ultimate loadings; and (4) develop a model to estimate the strand stress ranges in damaged girders.
