• 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.
