| 摘要： | Deterioration of the nation's bridges is a serious problem. High-performance concrete (HPC) is one of the technological improvements that is promising long-term, cost-effective results in highway bridge construction. The enhanced strength and durability characteristics of HPC in beams, decks, and piers reduces the lifetime cost and deterioration of these structures. The Federal Highway Administration (FHWA) is promoting the development, testing, and use of HPC by funding demonstration projects across the country. This article defines HPC, describes the origins of HPC, and discusses the difference between HPC and high-strength concrete. To encourage further research and the use of HPC, FHWA is showcasing HPC demonstration projects in regional events. Currently, eight states are active partners with FHWA in constructing or preparing to construct bridges with HPC. Five of those demonstration projects closest to completion are highlighted in this article. The states are Texas, Nebraska, Virginia, New Hampshire, and Ohio. Re-education of highway bridge construction professionals is necessary for the United States to fully realize the benefits of HPC technology. |
