摘要：	This project follows up on the original development of the defect correction index (DCI) in the Texas Department of Transportation project 0-6610. As part of implementing the DCI methodology for evaluating defect corrections using surface profile measurements, this implementation project conducted additional bump rating panels to verify the original DCI equation developed from project 0-6610. This verification led researchers to re-calibrate the original equation using the expanded bump rating panel database compiled in this implementation project. Researchers used the calibrated DCI equation in modifying the Grind Diagnostics program to automate the application of the DCI methodology for evaluating defect corrections on Item 585 projects or to identify treatments that can be made to an existing roadway during the project development and planning process to enhance the opportunity for ride quality improvement. In addition to automating the application of the DCI equation, researchers added a utility for estimating costs associated with correcting the defects identified from the DCI analysis and a utility for generating graphical output, through maps and charts, to help users communicate the results from this analysis.
