Bridge Deck Performance in Virginia
The Research Council's special study of bridge deck concrete included observation of construction and sampling on 17 structures distributed throughout Virginia with the exception of the easternmost (Suffolk) and westernmost (Bristol) highway construction districts. These decks were constructed during the spring and summer of 1963 under specifications, subsequently upgraded, which are now adjudged to produce concrete of 'borderline' performance in bridge decks. These decks have been under traffic for six winters. Because of the similarity of the objectives of the two studies it was deemed desirable to include during the survey of the 17 bridges of the Research Council's project a resurvey of the structures included in the PCA-BPR survey last inspected in 1961. The purpose of the resurvey was twofold: to assess the condition of the randomly selected group of bridges included in the PCA-BPR study and the change in their condition during the period 1961-1970 (the change will serve as a basis against which to compare the performance of the 17 bridges in the Council's research study during approximately the same time span), and, to establish the change in condition of the decks, particularly with regard to the further development of surface spalling to provide information which might allow a better understanding of the mechanics of this phenomenon.
