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…

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…

The use of recycled asphalt pavement (RAP) in asphalt mixes provides a vital basis for sustainable development. Maximising the re-use of RAP in its highest value application, as new asphalt product, has significant economic and environmental…

The current Austroads approach to assess the relative damaging effects of different axle groups on road pavements is by comparison of the peak static pavement deflection response under the axle groups. The assumption that deflection is the most…

This report brings together five years of research into the modulus, strength fatigue characteristics of cement treated granular materials as used in road pavements. Laboratory procedures used to prepare, cure and test materials for flexural modulus,…

The laboratory characterisation of cemented materials for road pavements was completed in Austroads Project TT1359 Cost-Effective Structural Treatments for Rural Highwaysand more recently in Austroads Project TT1664 Cemented Materials…

The report reviews current Australian and selected international structural design methods for pavements on lime-stabilised subgrade layers. Research to investigate in-service strength and modulus of lime-stabilised materials is also summarised. The…
