Abstract:
In the mid 1990s the Federal Highway Administration (FHWA) established a High Performance Concrete (HPC) program aimed at demonstrating the positive effects of utilizing HPC in bridges. Research on the benefits of using HPC for bridges has shown a number of benefits. These include increased span capacities or wider girder spacings (and hence a fewer number of girders); increased concrete compressive and flexural capacities; and improved concrete durability. However, in spite of all of these positive research results, relatively little has been done regarding the implementation of HPC in bridges in the United States. The general goals of the FHWA program are: to encourage the States to implement HPC in bridges; to develop appropriate mix designs and establish quality control procedures; to encourage the use of larger diameter [15 mm (0.6 in.)] prestressing strands in the girders; to evaluate the performance of the structure; and to provide for technology transfer through development of a workshop (showcase). This report presents preliminary test results from the first year of the materials testing program of the HPC mix used in the prestressed precast concrete girders on a bridge in the state of Washington. State Route 516 utilizes Washington State Department of Transportation 74G pretensioned I-girders with a 190 mm cast-in-place composite deck. The girders were fabricated with 15 mm diameter prestressing strands at 50 mm spacing, and designed for a concrete compressive strength of 69 MPa at 56 days. The material testing program includes determining compressive and tensile strengths, elastic modulus, long term creep, shrinkage, and thermal expansion properties of the HPC girder; and monitoring the compressive and tensile strengths and elastic modulus variation of the deck concrete. This is the second of a two part interim report. The first report is titled, "High Performance Concrete in Washington State SR18/SR516 Overcrossing: Interim Report on Girder Monitoring."
