Use of Road-grade Recycled Plastics for Sustainable Asphalt Pavements Part 2

December 16, 2021

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.
