Protocols for Network-Level Macrotexture Measurement

Research has shown that wet weather crashes are influenced by the macrotexture of the pavement surface. Therefore, availability of such data in pavement management systems would help highway agencies assess the adequacy of pavement surface macrotexture and determine if corrective measures are required. Methods commonly used for measuring macrotexture are cumbersome, therefore, there is a need to enhance available procedures or develop new procedures to provide better characterization of pavement surface texture. The objective of this research was to develop recommended protocols for test methods, equipment specifications, and data quality assurance practices for network-level macrotexture measurement. This information is useful for highway agencies that need to collect reliable network-level macrotexture data for use in pavement management systems. Available for immediate use, NCHRP Research Report 964: Protocols for Network-Level Macrotexture Measurement provides suggested protocols for macrotexture test measures, equipment specifications, and data quality assurance practices.
