Data on field performance of 132 bridge decks overlaid with latex mortar or concrete in Ohio, Michigan, Kentucky, and West Virginia, as well as some data from Minnesota and Vermont, were collected. Common durability distress features and the factors that might influence them were identified. Statistical analysis was performed to determine the set of variables that best explains the variation in the surface distress features among the different overlay projects investigated and to quantify the relationship between overlay condition and the pertinent variables through the formulation of regression models. Further assessment of available performance data was conducted to connect the obtained relationships with the limited data on effectiveness of latex overlays in providing corrosion protection to the deck rebars and to develop hypotheses on the formation and development of the durability deficiency features of latex overlays. The results obtained and the conclusions drawn explain, quantify and delineate the interrelationship among such factors as years of service, average daily traffic, trafficked versus untrafficked decks during placement, continuous versus simply supported decks, thickness of overlay, and skid number on the durability and corrosion-protection capability of the overlay.
