Opportunities exist across Canada for the greater use of recycled aggregates in road construction and other major infrastructure projects which, in turn, can deliver economic and environmental benefits. However, the lack of national standardization and specifications between levels of government and between jurisdictions leads to inconsistent application and a wide variability in the usage of recycled aggregates on infrastructure projects.
As a result, the ability of governments to integrate recycled aggregate through procurement is limited. Can a national, harmonized approach and set of standard specifications be developed to maximize the use of recycled aggregates for road construction?
In February 2022 Circular Innovation Council, in collaboration with Circular Economy Leadership Canada and other industry partners, brought together more than 90 key stakeholders from across Canada to explore the potential for greater use of recycled aggregates in road construction projects in Canada.
Breakout group discussions went deeper into the topic to better understand the barriers and opportunities for maximizing the use of recycled concrete aggregates for road construction in Canada.
