Austroads has completed its project APT6305 Use of Road-grade Recycled Plastics for Sustainable Asphalt Pavements which was investigating road-grade recycled plastics that can be used to construct and maintain asphalt roads.
The project results are provided in four reports:
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.
The second report provided a comprehensive overview of the development of various testing frameworks for the characterisation of road-grade recycled plastic, the incorporation of recycled plastics in bitumen and asphalt and the study of possible emissions and microplastics release.
Report 3 Part A presented the results of the experimental investigation on recycled plastics in asphalt and bitumen by focusing on the asphalt and bitumen properties, microplastics and emissions. The report focused on the wet and dry method of incorporation of plastics into asphalt.
This 75-minute webinar focuses on Part B of the third report outlining the mixed methods (i.e., low melting point plastics as additive to modify asphalt) performance and environmental assessment and expanding on the recyclability of reclaimed plastic-modified asphalt.
The webinar was presented by Andrew Papacostas from Department of Transport Victoria, Associate Professor Filippo Giustozzi from RMIT University and his team, including Dr Marie Enfrin, Yeong Jia Boom, and Dr Dai Lu Xuan.

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 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.
The second report provided a comprehensive overview of the development of various testing frameworks for the characterisation of road-grade recycled plastic, the incorporation of recycled plastics in bitumen and asphalt and the study of possible emissions and microplastics release.
The third report, the most comprehensive so far, presents the results of the experimental investigation on recycled plastics in asphalt and bitumen by focusing on the asphalt and bitumen properties, microplastics and emissions.
This webinar presents the outcomes of the project to date and covers the results of the multi-faceted (i.e. performance and environmental testing) laboratory investigation on bitumen and asphalt modified with recycled plastics. The session provides details on a potential framework for introducing the use of recycled plastics into current policies and specifications.
Webinar presenters are Andrew Papacostas from Department of Transport Victoria, Associate Professor Filippo Giustozzi from RMIT University and his team, including Dr Marie Enfrin, Yeong Jia Boom, and Dr Dai Lu Xuan.

Austroads project “Use of Road-grade Recycled Plastics for Sustainable Asphalt Pavements” is investigating the use of recycled plastics in asphalt. The project is well underway with results to date presented in two reports.
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.
The second report provided a comprehensive overview of the development of various testing frameworks for the characterisation of road-grade recycled plastic, the incorporation of recycled plastics in bitumen and asphalt and the study of possible emissions and microplastics release.
This webinar, presented by Andrew Papacostas, Dr Filippo Giustozzi, Yeong Jia and Dr Marie Enfrin, is the second session in a two-part series. It provides an overview of the outcomes of testing to date including techniques to assess emissions and microplastic release associated with the manufacture, placement and use of asphalt containing recycled plastic.
