• Abstract:
  This report presents a study focused on identifying the most durable expansion joints for the South
  
  Carolina Department of Transportation. This is performed by proposing a degradation model for the
  
  expansion joints and updating it based on bridge inspections.
  
  Open expansion joints and pourable joint seal were found to be the best performing joints based on
  
  the proposed degradation models. Assembly joints and compression joint seal have an intermediate
  
  performance and strip seal expansion joints have the lowest performance of the type of expansion
  
  joints studied. Assembly joints are found to be problematic because of the different moving parts
  
  composing the joint. A significant number of bridge joint failures are caused because of incorrect
  
  installation, in particular, joints with complex anchor systems between the bridge deck and
  
  expansion joint.
  
  The SCDOT standards were found to be up to date and comparable to other DOT standards in terms
  
  of the design and installation aspects of bridge joints. A recommendation is made to request a
  
  warranty for the installation of the when appropriate. Other general best practices during the
  
  installation of the expansion joint include: i) when possible, install joints when the ambient
  
  temperature is the average of the range of temperatures in the area. This allows the joint to be
  
  installed close to the “undeformed” position of the bridge, ii) the support of the joint should be
  
  installed in good quality, cured concrete, iii) avoid spliced of any pre-manufactured material. If
  
  splices cannot be avoided, place the splice outside the wheel path.
