Abstract:This is a report summary which summarizes a three year research effort related to the study of bridge deck expansion joint movements. Bridge deck expansion joint systems often develop serious problems requiring extensive and expensive maintenance. This has become a nuisance to users and to bridge engineers, and many states have been involved in investigations aiming to alleviate this problem. Results reported by various states regarding the behavior of specific joint sealing systems have been contradictory, indicating that the problems many not be inherent with the particular system. Rather, the problems many stem from a failure to properly assess the actual joint movements, inadequate design criteria, improper installation procedures or other factors such as differences in environmental conditions. In recognition of these problems, a comprehensive experimental and analytical investigation of bridge deck expansion joint movements was undertaken to develop rational design methodologies for joints in modern bridges.
