A Common Data Output Specification for Texture, Cracking, Strength and Skid Resistance

The report documents the development of a harmonised approach to road condition data management by Austroads member agencies.

It outlines the results of consultation with member agencies which considered principles, methods, specifications and their…

Investigating Key Performance Measures and Predictions on Unsealed Roads: Road Deterioration and Works Effects Models

This report details a study conducted using detailed roughness measurements on a panel of unsealed local roads located in Moorabool Shire Council at both the pre- and post-works effect (WE) treatment stages. The aim of the study was to develop…

Austroads LTPP/LTPPM Study - Summary Report 2013-14

This report summarises the activities undertaken during the 2013–14 year for the long term pavement performance (LTPP) monitoring project.

Practical Application of an Alternative Roughness Profile Validation Technique (Prem Method)

The main objective of this study was to assess the profiler gain validation technique as an alternative method for validating laser profilers that measure road roughness. The study sought to identify a suitable reference profiler against which other…

Traffic Speed Deflectometer: Data Review and Lessons Learnt

This report documents a review and comparison of Falling Weight Deflectometer (FWD) and Traffic Speed Deflectometer (TSD) deflections, based on different approaches, at a network level.

It draws on the work undertaken for Austroads by Roads and…

Traffic Speed Deflectometer: Data Analysis Approaches in Europe and USA Compared with ARRB Analysis Approach

This report documents discussions about international traffic speed deflectometer (TSD) data analysis and reporting held at the second Deflection and Road Traffic Speed workshop in Norway in June 2013. It also documents TSD data procurement and…

Double/Double Primerseal Inspections

This report describes inspections conducted on double/double primerseals constructed in Victoria.

It is not typical practice to use two-layer primerseals, or polymer modification in primerseals, and methods to do so are not described by Austroads…

Inspections of Sprayed Seal Trials

This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne, Victoria; and a polymer modified binder (PMB) trial near Coober Pedy, South Australia and…

Initial Field Trials with Surface Wear Rig

A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…

Good Practice in Reseal Programming

This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.
