• Abstract:
  This study is designed to assist the Ohio Department of Transportation (ODOT) in determining ; whether transitioning from manual to state-of the-practice semi-automated pavement distress ; data collection is feasible and recommended. Statistical and numerical comparisons are detailed ; between the pavement distresses, severities, and extents determined for 44 representative test ; sites by ODOT raters and those provided by three participating vendors. In response to the ; moderate to low initial distress (72 percent), severity (33 percent) and overall (14 percent) ; correlations, detailed methods for correlation improvement are provided. These methods are ; based on extensive interactions with ODOT pavement condition raters and participating vendors. ; Evaluations of system implementation costs and productivity rates offer supplemental information ; critical to ODOTs implementation decisions. Surveys of six vendors and 18 State agencies reveal the ; systems, processes, and experiences of those who provide and use automated methods for ; pavement distress data collection. Based on this information, recommendations for ; implementation activities, pavement management adjustments, procurement specifications, and ; equipment specifications are included.
