Hydrated lime is widely used in Australia to reduce the moisture susceptibility of asphalt mixes in service. However, the local asphalt industry is concerned about the sustainability of the continued use of hydrated lime in asphalt. This report…

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

This report provides a comprehensive overview of the initial development of various testing frameworks for the characterisation of road-grade recycled plastic, the incorporation of recycled plastics in bitumen and asphalt via various methods (wet,…

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…

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…

This report provides input to the Austroads project Performance of Warm Mix Asphalt Pavements. It involves a literature review of existing CO2-e emission calculators applicable to road construction (using asphalt products) with a view to…

The Austroads Guide to the Selection and Design of Asphalt Mixes does not address the design of mixes containing Recycled Asphalt Pavement (RAP). The report contains the additions and amendments which should be made to the next revision of the Guide…

A new, performance related asphalt mix design procedure was developed to address increased traffic stressing of pavements and to evaluate new mix types and new binder formulations. A series of Workshops was held in the capital cities of Australia…
