Book excerpt: This thesis presents the recommendation for whether the Georgia Department of Transportation (GDOT) should adopt the National Cooperative Highway Research Program (NCHRP) Report 747 (Guide for Conducting Forensic Investigations of Highway Pavements) as a guide to conduct forensic investigations. The evaluation of three pavement types using the NCHRP 747 guide is completed: Jointed Plain Concrete (JPC), Continuously Reinforced Concrete (CRC), and Hot Mix Asphalt (HMA). Each type consisted of an evaluation of two sites in "good/fair" and "poor" conditions. Non-destructive testing was performed using a Ground Penetration Radar (GPR) and Falling Weight Deflectometer (FWD). Destructive and on-site field testing were performed consistently with the recommendations of the guide. Laboratory tests were conducted to determine material properties and combined with traffic data to form conclusions about the causes of pavement distress. It is recommended from this study that the GDOT adopts the NCHRP Report 747 for use in Georgia.
