• Abstract:
  The Louisiana Department of Transportation and Development (LADOTD) initiated the Louisiana Quality ; Initiative (LQI) entitled “Preservation of Bridge Approach Rideability” to explore different potential ; methods of solving what has been observed as an approach-slab settlement problem at bridge ends. For ; LQI research to proceed, it was determined that a means of indexing bridge approach slab rideability and ; approach slab deformation would have to be developed. Traditional methods of roughness indexing like the ; International Roughness Index (IRI) and Ride Number (RN) along with alternative methods of indexing ; were examined in an effort to ascertain how localized (non-steady state) distresses, such as occur, at bridge ; transitions might best be indexed.
