Rideability of a Deflected Bridge Approach Slab (LTRC Project 02-2GT Continuation: Phase II). Final Report 2011-2014
This report presents the findings associated with an effort to develop a complementary pavement roughness indexing system that utilizes the 25 ft. Moving Baselength Roughness Index (IRI25-ft) alongside the posted speed localized roughness index (LRIPS) to find, index, and detect the types of bumps that appear on Louisiana highways. Currently established pavement roughness indices, such as ride number (RN), profile index (PI), and international roughness index (IRI), cannot effectively locate the position of bumps on the pavement due to inherent limitations. The complimentary index being proposed is intended to overcome these limitations. The IRI25-ft represents a methodology that the pavement indexing community has begun to utilize to evaluate bumps. For the purposes of this research, it is to be employed to index bump magnitude. The LRIPS was developed in a previous study carried out at the Louisiana Transportation Research Center (LTRC). For the purposes of this research, it is to be employed to locate the position of bumps on roadways and to identify bump type like faults and angle changes.
