Use of Road-grade Recycled Plastics for Sustainable Asphalt Pavements Part 3: Performance Outcomes

May 19, 2022

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.
