  • Abstract:
    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.
