• Abstract:
  This research developed a decision‐making process that can be used by INDOT to enhance identification of the condition of the ; underlying concrete joints or cracks by looking at the surface distresses of the asphalt overlay in composite pavements. In order to ; achieve the research objective, several tasks were performed during the research including literature reviews, data collection, and data ; analysis. In conjunction with the developed decision‐making process, this study also developed a database to organize the collected ; data and a computer application to not only increase the accessibility of INDOT field engineers to the sample data but also to improve ; the analysis process by providing better visualization tools. ; The data collection was performed based on four steps of field evaluation procedure (visual inspection of asphalt overlay, FWD testing, ; Coring, and visual inspection of exposed concrete). The collected data was analyzed to show distribution of joint and mid‐panel cracks, ; and correlation between asphalt crack severity and concrete crack severity. Four input factors from the analyzed data (visual inspection ; of asphalt overlay, D1, LTE, and Resilient Modulus) were selected to develop the decision‐making tool. ; A handbook is also provided to help INDOT field engineers’ decision‐making during their field activities. The handbook contains ; important information of pavements, photographs of cracks, and the exposed concrete condition of sample data points for the benefit ; of field engineers. Recommendations and limitations are also discussed in this report.
