Abstract:The premature deterioration of concrete bridge decks due to salt-induced corrosion of reinforcing steel has become a major highway maintenance problem in the U.S. Evidence of this type of damage has appeared on some Alaskan bridge decks, some of which have required expensive repair work. The Bridge Deck Corrosion Project was undertaken to gain a better understanding of this problem in Alaska and to recommend actions which the Alaska Department of Transportation and Public Facilities can take to protect Alaska's investment in highway bridges. The conclusions of the project are presented in Chapter 1 of this report. As part of the project, a literature review was made of the mechanism of deck corrosion problems and the past or proposed methods of their prevention and repair. This is presented in Chapter 3 of this report. Chapter 4 contains a discussion of bridge deck repairs which have been made in Alaska, their costs, and the performance of these repairs since they were made. Detailed inspections were made on a number of bridge decks throughout Alaska in order to assess the severity of the corrosion problem in the state. The results of the tests are presented in Chapter 5. The interpretation of test results, the limitations of specific tests, and potential difficulties in testing programs are discussed in Appendix A. Appendix B contains unit cost information for concrete bridge decks and for systems to prevent and repair corrosion problems in those decks. This information was used in developing the recommendations in this report, and should be useful in estimating the costs of future deck construction and repair projects.
