This report contains the findings of research performed to investigate the application of nondestructive testing (NDT) technologies in the quality assurance of hot mix asphalt (HMA) pavement construction. The report contains the results and analyses of the research performed and presents several key products, notably a recommended manual of practice with guidelines for implementing selected NDT technologies in an agency's routine quality assurance (QA) program for HMA pavement construction and detailed test methods for the recommended NDT technologies. Thus, the report will be of immediate interest to construction and materials engineers in state highway agencies and the private sector.
