    16. Abstract Six sections of jointed plain concrete pavements (JPCP)s throughout the state were selected as

    candidates for the evaluation of premature deterioration. The data used in performing the evaluation included manual

    and historic automated distress survey data, falling weight deflectometer data, and laboratory material

    characterization data from field samples. For these six sections, a variety of issues including material-related distress,

    fatigue, and construction deficiencies were determined to be the cause of the premature deterioration.

    Recommendations for rehabilitating these sections as well as guidelines to deter the reoccurrence of these distresses

    have been provided.
