This report describes research into the development of a draft Austroads evaluation protocol for rejuvenators. Rejuvenators are typically used to produce asphalt mixes containing high levels of reclaimed asphalt pavement (RAP). The report includes a…

This seminar was held on 2 September 2022 at RMIT University in Melbourne. It was sponsored by Austroads and attracted an audience of more than 400 people across the world. The 4-hour recording considers different perspectives of incorporating waste…

Road tunnels are an important element of the transport infrastructure, requiring significant resources and energy to construct, operate and maintain. Consequently, they are potentially a major source of greenhouse gas emissions and environmental…

Austroads Project APT6305 Use of Road-grade Recycled Plastics for Sustainable Asphalt Pavements is investigating the use of recycled plastics in asphalt. The project is almost completed with results to date provided in three published reports. The…

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 documents a project undertaken to investigate the issues associated with managing the planning, construction, operation and maintenance of road tunnels in a sustainable manner. The results of the investigation informed an update to all…

Road tunnels are major pieces of infrastructure across the road network, and the number of tunnels is expected to increase in the coming years. Although they are relatively safe, a significant number of crashes occur on the approaches to and within…

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…
