摘要

In order to document the? various applications of bridge deck panels in North America, a questionnaire survey was sent to the departments of transportation (DOTs) of individual states and one province. Requested? information in the survey included type of construction, deck dimensions, deck supporting system, panel dimensions and reinforcement, type of connecting system between panels and supporting system,? type of joint between the adjacent panels, type of bonding material used to fill the joints, problems associated with the joints, reasons for adverse results, and type of protection system. The returned questionnaires were compiled and analyzed. This paper summarizes the significant results of this survey.?
