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 documents a project to develop a new laboratory fatigue relationship to predict the performance of foamed bitumen stabilised (FBS) materials. The project focused on extensive laboratory experiments including indirect tensile testing and…

This report provides an evaluation framework, practices and supporting tools for evaluating road preservation and renewal treatment options for predominantly sprayed seal flexible pavements. It includes a compilation of case studies based on a…

This report details research undertaken to improve the mechanistic-empirical procedure for pavement rehabilitation and strengthening treatment design included in Austroads Guide to Pavement Technology Part 5: Pavement Evaluation and Treatment Design.…

This report provides a comprehensive overview of the type, volume, and price of recycled plastics and their possible uses in asphalt. The report presents data, including recycling processes, prices of recycled plastics, annual production volumes and…

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…

Guidelines and Specification for Microsurfacing provides guidelines for the use of microsurfacing treatments in Australia. Microsurfacing is presently the only type of bituminous slurry surfacing applied in Australia. The document was produced by…

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…
