Performance Measures and Targets for Transportation Asset Management | Research Report
The two volumes included in this report--Volume I, Research Report, and Volume II, Guide for Performance Measure Identification and Target Setting--will help transportation agencies apply the concepts of performance management to their asset management efforts. Volume I describes the research effort and provides the current state of practice on the use of performance measures, principally in the context of transportation asset management. Volume II introduces a framework for identifying performance measures and setting target values, and its appendixes contain examples of performance measures and targets. The emphasis was on highway infrastructure assets. Performance measures and target values are critical to the principles of asset management to analyze tradeoffs, make investment decisions, and monitor intended effects. The report will be of interest throughout transportation agencies as an aid to effective decision making and the optimization of resources.

Guide to Asset Management Part 5C: Rutting | Research Report
Asset Management, PavementThis 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.
Guide to Asset Management Part 5E: Cracking | Research Report
Asset Management, PavementThis document contains guidelines for and background notes on network level measurement and reporting of pavement cracking data for road network management purposes in Australia and New Zealand. The guidelines discuss the types and causes of cracking, the frequency and scope of network cracking surveys, and the methods available for network level cracking surveys. The guidelines describe four current principal methodologies for measuring surface cracking at a network level in Australia and New Zealand, viz. detailed walk-over inspections, drive-over windscreen surveys, manual post-interpretation of video images of pavement surfaces, and fully automated techniques involving high-resolution imaging and automated crack recognition. The guidelines recognise and define three parameters for reporting cracking, viz. dominant crack type, severity (crack width), and extent (proportion of total surface area cracked). The guidelines are intended as a basis for a consistent approach in Australia and New Zealand. Verification procedures for cracking measurement methods are covered, and repeatability and bias are briefly discussed. A glossary of terms used in network level assessment of road surface cracking and a summary of a literature review of practices for collecting cracking data are included. (a)
Guide to Asset Management Part 5B: Roughness | Research Report
Asset Management, PavementThis 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 wavelengths between 0.5 metres and 50 metres. The guidelines describe two broad measures of roughness, viz NAASRA Roughness Meter (NRM roughness values in counts per kilometre) and the International Roughness Index (expressed in units of metres per kilometre), and mark the introduction to Australasia of Lane IRI as a standard form of reporting road pavement roughness. A standard reporting interval of 100 metres 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 network roughness surveys. Verification 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. (a) Austroads Project AP1009
