• 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.
