Investigation, assessment, approval and management of bridge deck joints by RTA NSW

Deck joints are simple elements in bridges but are heavily impacted by moving traffic. They are susceptible to damage and their repair is costly due to the need for lane closures and traffic control at the worksite with installation often being at night. A computer module was developed to document the history of Roads and Traffic Authority (RTA) joints and is used as a condition assessment tool. The Bridge Joint Assessment (BJA) module assesses joint condition and performance rating using field inspection of several simple items, and can also be used for monitoring performance of a particular joint or joint type. To minimize its risk, RTA mandated and implemented an approval process for proprietary deck joints for RTA bridges and those that will become property of RTA. RTA only allows use of unapproved joints when proven to comply with AS 5100.4. Lists of RTA approved bridge components and systems are published on RTA's internet site and are regularly updated. Its systematic approach for managing deck joints has been initiated to reduce maintenance costs and to safeguard the travelling public and RTA workers.
