A Comparison of Bridge Deck Roughness: 1963 and 1965
In 1963 the Virginia Council of Highway Investigation and Research initiated a study to determine the degree and causes of bridge deck roughness. Based partially on the preliminary results of this study, special provisions for finishing bridge decks were issued by the Department of Highways for all structures constructed after April 1, 1964. This report presents a comparison of the riding quality of bridge decks constructed before and after adoption of the special provisions. The increased emphasis on obtaining smoother bridge decks proved fruitful regardless of the construction techniques used, with bridge decks constructed subsequent to the 1964 special provisions having, on the average, appreciably better riding qualities than those constructed prior to 1964. Longitudinal screeding produced the smoother bridge decks and this method of screeding was used more frequently after issuance of the 1964 special provisions which stated preference for the method. Considerable variation in the roughness of bridge decks screeded by the same method suggests that control and quality of workmanship and equipment must be maintained at high standards to obtain results capable of being achieved.
