• Abstract:
  Recent concerns of misaligned dowel bars led to a technical assistance project
  
  to investigate the roadways in question using a MIT-SCAN-2 device borrowed
  
  from the Federal Highway Administration (FHWA). The device worked extremely
  
  well, and the Louisiana Department of Transportation and Development (DOTD)
  
  is considering its use in quality control and assurance. Dowel bar alignment has
  
  rarely been questioned in Louisiana due to the inability to check and because
  
  dowel related issues have not materialized, so new guidelines for dowel bar
  
  placement alignment and testing need to be developed. Such guidelines should
  
  consider the minimum alignment requirements to mitigate premature pavement
  
  failure due to load transfer or faulting because of the misaligned dowel bars.
