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…

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 Pavement Work Tip details the production and paving of EME2, a high modulus asphalt produced with a very hard paving grade bitumen and a high binder content.

Asphalt pavements are a major component of the Australian and New Zealand road networks. Road agencies in Australia and New Zealand have been putting great efforts to produce pavements which perform and are long-lasting. This has led to the…

The ban on the export of recycled waste plastic by the Australian government has led to interest in the use of recycled waste plastic in road surfacing applications. Austroads has published a report, Interim guidelines for the use of recycled waste…

This report describes research work into the development of a new test method utilising the dynamic shear rheometer (DSR) to conduct consistency 6% at 60 

This Pavement Work Tip provides a guide to the light application of bituminous binder to an existing asphalt or spray seal surface to increase the binder level on the surface and prevent aggregate loss.

As a result of the ban on the export of recycled waste plastic, there is increasing interest in repurposing recycled waste plastic for use in road surfacing applications. There is no guide for this purpose and until such time as a guide is available…
