This document contains guidelines for and background notes on measurement and reporting of rutting or transverse profiles for road network management purposes in Australia and New Zealand. The guidelines define rutting as a longitudinal surface depression usually in a wheel path. The guidelines have been prepared in the context of measuring rutting either manually with a straight edge or using a vehicle mounted non-contact multi-sensor transverse profile measurement device. Regardless of the method of measurement, the guidelines express a preference for rut depth to be reported with reference to a 2 m straight edge. This is consistent with the HDM-4 approach. A standard reporting interval of 100 m is favoured. The guidelines discuss the frequency and extent of network rutting surveys, and are intended as a basis for the preparation of specifications for surveys of network rutting. Verification procedures for profilometers, and limits on repeatability and bias for rutting reports are included. The document also discusses the uses of rutting data in road pavement management at network and project levels and provides guidance on analysis techniques for rutting data for different applications. A glossary of terms used in measuring road pavement rutting is also included.
