This report is Part B of the third report for the APT6305 project. The first report examined road-grade recycled plastics in asphalt pavements and investigated the most suitable types of recycled plastics for incorporation into the asphalt. The…

This report identifies and evaluates technology solutions that meet asset management needs relating to road pavement performance. The increasing pace of change of technology brings considerable promise of more data, of a higher quality, captured for…

There is a need to improve Austroads procedures for the structural design of pavements containing lightly bound cemented (LBC) materials. This report describes the findings of an investigation of the performance of Queensland pavements with LBC…

Earlier Austroads investigations seeking to develop Bridge Formulae for inclusion in the Performance Based Standard Network Classification Guidelines concluded that there is little benefit to be gained from attempting to recompose the existing…

The May 2018 National Transport Commission review of the Australian Performance-Based Standards (PBS) scheme revealed the need to improve the efficiency of heavy vehicle access via the PBS scheme to access substantial national freight productivity,…

Bridge assessments to AS 5100 express safety as a binary (yes/no) measure. The management of bridges deemed unsafe using this deterministic method is outside the scope of the standard. From international practice, the most holistic approach that…

This report documents the options and methodologies available to conduct higher order assessments of existing bridges which are encouraged by but not currently defined by the new AS 5100.7. This was achieved by investigating the current…

This report presents the proposed future directions for long-term pavement performance (LTPP) studies in Australasia. The proposed way forward is based on the results of a 2017 survey directed to the LTPP Project Steering Group (PSG) and Assets Task…

The aim of this project was to clarify the effectiveness of pavement maintenance (preservation) activities, in the form of periodic maintenance and rehabilitation, on pavement condition and distress (roughness, rutting and cracking) deterioration…

This report extends on the work previously conducted by Austroads in investigating the development and implementation of a national automated bridge assessment framework. The work outlines the ongoing validation works and recommends a set of…
