| Abstract | The high-performance concrete (HPC) bridge, located in Brookneal, Virginia is a two-lane 13.4-m-wide (44-ft-wide) structure made up of four equal spans that are 24.4 m (80 ft) long. Each of the simple spans consists of five AASHTO Type IV pretensioned concrete I-beams. The beams are spaced at 3.1 m (10.3 ft) on center. The HPC bridge contains five beams, compared to the seven beams needed if the bridge had been designed as a conventional concrete bridge. This resulted in a net savings of eight beams for the four-span bridge. The bid bridge construction cost was $527/sq m ($49/sq ft). This may be compared to the 1994 average of $624/sq m ($58/sq ft) for 34 bridges in the Federal-aid highway system in Virginia. The initial savings over conventional bridge concrete and construction was estimated to be 4%. |
