Abstract:

The Louisiana Transportation Research Center has worked closely with the Bridge ; Design section of the Louisiana Department of Transportation and Development ; (DOTD) to develop a workable specification for standard and localized roughness ; of bridges. ; The draft specification has two components: standard assessment of the overall ; International Roughness Index (IRI) of a bridge and localized assessment of ; individual bumps, faults, and slope changes. ; DOTD has extensive experience with standard IRI measures of pavement ; roughness, but this experience is not directly transferable to bridges. DOTD also ; has experience with localized roughness, but that experience has never been ; applied to project acceptance. This project is an attempt to use the draft specification on pilot projects to assess ; the specification’s strengths and weaknesses and to refine the specification as ; needed. The objectives of the research are to decrease roughness on Louisiana ; bridges and to assess benefits and costs associated with doing so.
