Assessing Pavement Layer Condition Using Deflection Data

An NCHRP digest of the findings from the final report on NCHRP Project 10-48, "Assessing Pavement Layer Condition Using Deflection Data," conducted by North Carolina State University. Dr. Y. R. Kim served as Principal Investigator. The agency's final report gives a detailed account of the project, findings, and conclusions, including software for the analysis of the condition of layers of full-depth AC pavements and AC pavements with untreated granular bases. The report, which was distributed to NCHRP sponsors (I.e., the state departments of transportation), is available for loan on request to the National Cooperative Highway Research Program, Transportation Research Board, 2101 Constitution Avenue, N.W., Washington, DC 20418.
