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 documents the findings from a research study, which aimed to investigate driver behaviour and perceptions while driving through a simulated version of the Sydney NorthConnex (NCX) road tunnel and evaluate the effectiveness of aesthetic…

This report documents the findings from a research study which aimed to validate the use of a virtual reality (VR) driving simulator to study driving behaviour in a real road tunnel.

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 evaluates selected low-cost perceptual countermeasure (PCM) treatments in tunnel environments. PCM treatments are used to reduce crash risk by improving driver speed behaviour, alertness and lane discipline within tunnels. Two key…

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…

This report provides guidance on consistent, efficient and safe design of emergency egress signage and operations in road tunnels. While there are Australian Standards relating to emergency egress signage, these were not originally intended for use…

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…
