Abstract:

Side-by-side box-beam bridge constitutes approximately 17 percent of bridges built or replaced annually on public roads and there is a renewed thrust to use this bridge type for rapid construction under the Highway for LIFE program. Further, failure of a fascia girder of Lakeview Drive bridge in Pennsylvania on December 27, 2005 and with a large number of aging bridges in the U.S., highway agencies are concerned about the safety of similar bridges. This project was developed to evaluate the capacity of distressed box-beam through load testing; investigate the impact of distress types identified during phase I of this project on flexure and shear capacities of a beam in a structural system; identify proper materials and methods for long lasting repairs to improve the structural integrity of distressed box-beam bridges; and by performing simulations of the construction process using finite element (FE) models investigate stresses developed in components during each stage of construction and under operation, develop recommendations for changes or modifications to the design procedures, construction process, material specifications, and to the maintenance and repair techniques of side-by-side boxbeam bridge deck. Six tasks were performed in this project ranging from literature review, instrumentation and load testing of a severely deteriorated fascia beam, laboratory investigation of fresh and hardened (durability) properties of shear key grout and repair materials, evaluation of mechanical properties of shear key grout and repair materials, construction process simulation, and evaluation of flexural and shear capacities of distressed beams considering structural system behavior. Recommendations of this project include selection of repair and shear key material, development of comprehensive inspection procedures to assure bridge safety and implementation of the rational design procedure given in the report for improved durability.
