Abstract:

The high-performance concrete (HPC) bridge carrying U.S. 401 over the Neuse River in Raleigh, North Carolina consists of two parallel structures, each with four spans--two spans of 28.0 m (91.9 ft) and two spans of 17.5 m (57.4 ft). Each bridge is 14.4 m (47.1 ft) wide and carries a 12.0-m (39.4-ft) roadway section and a 1.9-m (6.2-ft) sidewalk. The bridges have simple-span prestressed concrete I-girders made continuous for live load. AASHTO Type IV prestressed concrete I-girders are used in the 28.0-m (91.9-ft) spans, while AASHTO Type III prestressed concrete I-girders are used in the 17.5-m (57.4-ft) spans. Girder spacings are five girders per span at 3.12 m (10.25 ft) on center and the deck thickness is 215 mm (8.5 in.). A reduction in the number of girders, diaphragms, and bearings offset the additional cost of the HPC. The life-cycle cost-savings are expected to be significant due to enhanced durability. Instrumentation of the girders will provide valuable insight into future use of 15.2-mm-diameter (0.6-in.-diameter) strands, fly ash in bridge decks, and mix design requirements for 60 MPa (10,000 psi) concrete.
