Forensic Pavement Evaluation For Us 31 W, Jefferson County, Kentucky Using Ground Penetrating Radar, Brad W. Rister, Kean Ashurst, R. Clark Graves
Kentucky Transportation Center Technical Assistance Report
The Kentucky Transportation Center (KTC) utilized ground penetrating radar technology to provide a forensic evaluation of the existing pavement structure for the US31W pavement rehabilitation Project in Jefferson County, KY. Processed ground penetrating radar data indicated that the integrity of the underlying concrete pavement beneath the asphalt pavement appears to be competent and structurally sound. The clay soil beneath the concrete pavement appears relatively dry and well compacted. The analyzed GPR data also indicated that the average asphalt layer varied by lane throughout the project from 4.89 to 7.59 inches +/- ½ inch and that the underlying concrete layer average …

Highway Rail Crossing Prioritization, Bryan Gibson, Reginald R. Souleyrette
Kentucky Transportation Center Technical Assistance Report
Research team members at the University of Kentucky in the Department of Civil Engineering and the Kentucky Transportation Center (KTC) worked with the Kentucky Transportation Cabinet (KYTC) to develop a high-level mechanism for ranking highway-rail crossings for reconstruction and/or rehabilitation. The Highway Rail Crossing Prioritization implementation study yielded the Rail Crossing Improvement Priority (RCIP), which combined qualitative measures of crossing conditions with quantitative measures including proposed project costs and a valuation of the crossing based on rail and truck traffic. This effort provides a template by which further development can yield prioritization procedures for road-rail grade separation projects.
