The objective of this project is to identify how recycled materials may be reutilised as earthworks and drainage materials. Following the extensive review of literature and findings in Year 1, Year 2 has focused on investigating the engineering and environmental characteristics of recycled crushed concrete (RCC), reclaimed asphalt pavement (RAP) and coal combustion products (CCP), including both fly ash (FA) and bottom ash (BA), through extensive laboratory testing. The objective was to explore the impact of utilising these recycled materials in earthworks from performance, environmental, and work, health and safety (WHS) points of view. A suitably qualified professional (SQP) was engaged to conduct the environmental and WHS assessment.
