This report contains guidelines for and background notes on the conduct of response-type and profile-based roughness measurement for road network management purposes in Australia and New Zealand. The guidelines define roughness as being concerned with road surface profile wavelength between 0.5 m and 50 m. The guidelines describe two broad measures of roughness, viz NAASRA Roughness Meter (NRM roughness values in counts/km) and the International Roughness Index (with a specific focus on Lane IRIqc, expressed in units of m/km) and mark the introduction to Australasia of Lane IRIqc as a standard form of reporting road pavement roughness. A standard reporting interval of 100 m is favoured. The guidelines discuss the frequency and extent of network roughness surveys, and are intended as a basis for the preparation of specifications for netwrk roughness surveys. Verfication procedures for inertial profilometers, testing frequencies and limits on repeatability and bias for roughness reports are included. A glossary of terms used in measuring road roughness is also included.
