To develop new ways to use recycled materials in local road and construction projects through field trials and testing
Create a modelling system to predict how concrete with recycled materials will perform over time
Develop fast and reliable testing methods for concrete exposed to harsh conditions like marine or acidic environments
Investigate how crumb rubber asphalt ages and create a lab method to simulate this process
Conduct field trials of concrete and asphalt made with recycled materials in partnership with councils and industry
Measure the environmental impact and long-term costs of using these recycled materials in roads and construction
Test innovative treatments using recycled tyres to protect roads from sun damage and extend their lifespan
Share research results widely to help build a global network focused on recycled construction materials

This project is led by RMIT, in collaboration with Hokkaido University in Japan, alongside the Cities of Hobsons Bay and Brimbank. It focuses on using recycled materials in local government construction projects, backed by field trials.
So far, the project has delivered detailed modelling of concrete made with recycled coarse aggregates, forming the base for future modelling of other waste materials. Researchers are developing a digital modelling tool to predict the durability of concrete using waste products, including its resistance in harsh environments.
The team has also created methods to recycle crumb rubber asphalt in the lab, tested new concrete and asphalt mixes in both lab and scaled-up field trials, and assessed their environmental and cost impacts.
Notably, new road treatments using recycled tyres have shown strong resistance to ageing and sun damage, extending pavement life. The project has been presented at five national and international events, helping grow a global network of experts in this field.
