• Description:
  Deterioration of bridge substructures has been a serious concern throughout Wisconsin. Concrete, steel and
  
  timber components all require distinct repair methods which not only address the true cause of the deterioration,
  
  but also protect the component from future damage. In order to determine common repair practices and their
  
  success rates, the research team surveyed maintenance engineers throughout the United States to determine
  
  successful and reliable substructure repair techniques. The survey indicated that concrete surface repair is the
  
  most common repair technique, and was also viewed as the most unreliable. The survey results indicated that
  
  the most reliable repair technique for scour was the correct sizing and use of riprap. Eight bridges were visited
  
  throughout the Southeast and Southwest regions of WisDOT. These bridges were documented, both for their
  
  typical deterioration and unique repair methods. Various methods and procedures of repairing concrete, timber
  
  and steel substructures, and countering scour were summarized and discussed. Decision matrices were created
  
  to compare different repair methods based on their unit costs and estimated service life. A repair manual
  
  including detailed and drawing and procedures of 72 different repair methods was created for use by WisDOT
  
  personnel.
