Optimising the use of recycled materials in Queensland for unbound and stabilised products: Year 1 (2018/2019)

The use of recycled materials as unbound and stabilised granular pavement materials has traditionally been relatively low in Queensland, despite the Queensland Department of Transport and Main Roads (TMR) permitting the use of recycled materials. This report outlines the first year of a multi-year project where the primary objective of Year 1 was to review the use of recycled materials nationally and to identify ‘quick wins’ that could help facilitate the immediate increased use of recycled materials in unbound and stabilised granular materials in Queensland. The approach undertaken may be summarised as follows: defining the waste streams for Australia at the national level, and for Queensland at the state level to provide the context and outline of the potential barriers to implementation; reviewing the existing practice for each of the Australian state road agencies with regard to the specifications and permissible uses of recycled materials in unbound and bound pavements; reviewing and documenting the environmental requirements of using recycled materials in Australia-wide pavement applications; and summarising the findings based on the project outcomes, recommending any changes to current TMR practice and outlining the scope for Year 2 of this project.
