The costs of sourcing traditional pavement materials are increasing as sources are being exhausted, haulage distances are increasing, and access to traditional sources is increasingly restricted. As a result, jurisdictions are seeking alternative solutions, one of which is the use of recycled materials.

This report includes details of a two-year survey process which sought information on the use of local and recycled pavement materials by Australian jurisdictions. The survey focused on construction and demolition waste.

The report provides an estimate of the financial cost savings when incorporating recycled aggregates into pavement bases. It also sets out the environmental and social considerations associated with recycling and resource use.

Two detailed case studies examine the experience of a local council in New South Wales and industry in South Australia.

The report suggests there are significant economic and environmental benefits associated with the incorporation of recycled aggregates in pavement bases.
