Based upon the findings of this study, recornmendations were made for possible improvement of the currently used design and management procedures. Specific recommendations were made for improved material specifications to avoid stripping in the pavement structure as this was found to be the most imnortant reason for the failure of pavements. A research plan has been proposed for future research.53 pages18,310,305 bytesapplication.pdfTechnical ReportCompositeEvaluationFlexibleNon-destructiveOklahomaPavementRigidRuttingStrippingStructural Number
