Performance of Common Treatments for Reinforced Concrete Highway Bridge Decks Public Deposited
  • This study gathers information on more than 15,000 bridges to examine time domain trends in condition of bridge decks in service that employ several common treatments. This study computes average improvement to deck condition due to these treatments and computes the mean intervals of changes in general condition ratings related to the deck’s post-treatment condition and its approximate pre-treatment condition. In addition, this study performs a cost analysis to compare the average unit cost and the cost effectiveness of each treatment. The results show an average improvement to deck condition of 1.31 rating values due to treatment, mean intervals to maintain approximate post-treatment condition ranging from 6.6 years to 19.4 years, and mean intervals to deteriorate to approximate pre-treatment condition ranging from 13.2 years to 29.4 years. Average costs of treatments range from $0.34 per square foot to $14.68 per square foot. Cost effectiveness is computed as cost per duration in years of improved conditions. Cost effectiveness ranges from $0.06 per square foot per year to $0.99 per square foot per year.
