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.
