• Abstract:
  Replacing aging, deteriorated infrastructure often requires road closures and traffic detours which impose ; inconvenience and delay on commerce and members of the motoring public. Accelerated bridge construction ; techniques often use precast members to reduce the duration of construction and the resultant disruption to traffic ; patterns. ; This project considered various technical, safety, and economic challenges in the design and construction of a full-width precast concrete slab with a centerline crown. Torque verified leveling screws compensated for girder, deck ; panel prefabrication tolerances, and dead load deflections. In addition, the uniform-depth deck slab was cast by ; conventional prestressing fabricators. The method to lift and transport the slabs was considered to prevent damage. ; Accelerated bridge construction is less expensive and bridge work can be c
