To develop clear, practical guidelines for using recycled plastic in asphalt roads
To trial and monitor recycled plastic asphalt mixes on roads across 10 Victorian councils
To collect and analyse field and lab data to improve road performance and increase recycled plastic use
Filippo Giustozzi
This project partners with 10 Victorian councils to trial recycled plastic asphalt on local roads, aiming to improve road performance and boost the reuse of waste plastic.
Road construction across all participating councils was completed between February and June 2024.
Field inspections in July 2024 assessed the early condition of the roads, including rutting, cracking, and surface smoothness, with data collected by NTRO and shared with RMIT for further study.
Laboratory testing on road samples is around 60% complete, with remaining tests paused until RMIT’s Bundoora lab reopens.
The results from these trials will help create practical national guidelines for councils, road builders, and recyclers.
