• Abstract:
  Prestressed concrete panels have been used by the bridge construction industry in the state of Texas for many ; years to increase construction speed and improve safety and economy. At expansion joints, cast-in-place concrete ; is used and requires temporary formwork and slows construction. In a previous TxDOT project (0-4418), a fullscale ; bridge deck was constructed that included precast panels at a 0o skew. The results indicated that the precast ; panel system provided adequate strength and reduced construction costs compared with the traditional cast-inplace ; details at the expansion joint. In this investigation (TxDOT Project 0-5367) two areas not covered in ; Project 0-4418 were studied: fatigue performance of bridge decks using precast panels at the expansion joints and ; the use of precast panels at skewed expansion joints. Fatigue response of precast panels under loading at the ; expansion joint in 0o skew bridges was excellent. Skewed precast panels at expansion joints were tested under ; static and fatigue loads. Two skew angles were tested: 30o and 45o. Six specimens were constructed and ; subjected to a total of eleven tests. Loads were applied at midspan of the skewed end of each specimen, and some ; specimens were also loaded at joint between trapezoidal (skewed) panels and an adjacent rectangular panel. The ; skewed panels performed well. Design recommendations for implementation of skewed panels were developed.
