A SURVEY TO DETERMINE THE IMPACT OF CHANGES IN SPECIFICATIONS AND CONSTRUCTION PRACTICES ON THE PERFORMANCE OF CONCRETE IN BRIDGE DECKS
In response to its own research and observations in the early 1960's, the Virginia Department of Highways mounted an intensive and extensive effort to improve the performance of concrete in bridge decks. Major elements of this effort included 1) a training and certification program for Department and industry personnel and 2) improved and upgraded specifications for both materials and construction practices. In 1972 a survey was made of 129 randomly selected bridges constructed after 1966, when all the improvements had been formally instituted. The performance of these bridges was compared with that of a similar sample that had been surveyed in 1961. In addition to the visual observation of performance measurements of electrical corrosion potentials and depth of concrete cover were made in the 1972 survey. Based upon this survey, several conclusions and recommendations were made.
