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 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…

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…

This report is the final deliverable of a three year Austroads project to improve the design procedures for asphalt pavements. The object of the work in this final year was to validate the proposed improved procedures for the characterisation of…

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,…
