  • 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.
