Abstract:

The HPC bridge is a simple-span structure, 18.3 m (60 ft) long. The bridge consists of two travel lanes, shoulders, and one sidewalk. The bridge superstructure is 12.0 m (39.5 ft) wide and consists of four New England Bulb-Tee (NEBT) prestressed concrete girders spaced 3.5 m (11.5 ft) on center, with a 229-mm- (9-in-) thick deck. The NEBT girder section, which was recently developed for the region as a new economical section, incorporates the use of HPC and 15-mm- (0.6-in-) diameter low-relaxation prestressing strands. The bridge deck consists of 89-mm- (3.5-in-) thick precast prestressed deck panels overlaid with 140 mm (5.5 in) of castin-place HPC concrete. Conventional concrete, 28 MPa (4000 psi), was used in the at-grade approach slabs for comparison purposes.
