Specifying and Measuring Asphalt Pavement Density to Ensure Pavement Performance

TRB's National Cooperative Highway Research Program (NCHRP) Research Report 856: Specifying and Measuring Asphalt Pavement Density to Ensure Pavement Performance examines the current state of knowledge and existing agency practices to measure and specify the in-place density of asphalt pavements. The report aims to guide agency decisions on selecting measurement methods and requirements for in-place density and identifies the specific knowledge gaps that need to be addressed to provide a complete basis for establishing more comprehensive density standards.
