• Abstract:
  Bridge deck expansion joints are used to allow for movement of the bridge deck due to thermal expansion, dynamics loading, and ; other factors. More recently, expansion joints have also been utilized to prevent the passage of winter de-icing chemicals and ; other corrosives applied to bridge decks from penetrating and damaging substructure components of the bridge. Expansion joints ; are often one of the first components of a bridge deck to fail and repairing or replacing expansion joints are essential to extending ; the life of any bridge. ; In the Phase I study, the research team focused on the current means and methods of repairing and replacing bridge deck ; expansion joints. Research team members visited with Iowa Department of Transportation (DOT) Bridge Crew Leaders to ; document methods of maintaining and repairing bridge deck expansion joints. Active joint replacement projects around Iowa ; were observed to document the means of replacing expansion joints that were beyond repair, as well as, to identify bottlenecks in ; the construction process that could be modified to decrease the length of expansion joint replacement projects. ; After maintenance and replacement strategies had been identified, a workshop was held at the Iowa State Institute for ; Transportation to develop ideas to better maintain and replace expansion joints. Maintenance strategies were included in the ; discussion as a way to extend the useful life of a joint, thus decreasing the number of joints replaced in a year and reducing the ; traffic disruptions.
