Unbound granular pavements are commonly used for low-volume roads in Queensland, Australia, with Unbound Granular Materials (UGMs) being the primary construction material, classified into five main standard material types by the Queensland Department of Transport and Main Roads (QDTMR), is the primary material used in constructing these pavements. However, the high demand for crushed rock has raised concerns about resource depletion. As a result, road agencies are increasingly exploring alternative materials, such as Recycled Concrete Aggregate (RCA), to replace conventional UGMs. RCA is currently used as a base and subbase material in pavement construction without adhering to existing standards. However, RCA must meet the performance criteria of standard UGMs to gain widespread adoption. This research evaluates RCA’s geotechnical and transport-related characteristics to match the performance characteristics of high-quality Standard Material (SM01), low-quality Standard Material (SM02), or fall within this range of UGMs based on laboratory-based experiments. The study compares the basic properties, including grain size distribution, Atterberg limits, specific gravity, compaction characteristics, and California Bearing Ratio (CBR) values of RCA against those standard materials. The analysis classifies RCA gradation and deploys CBR tests and standard compaction tests to assess RCA’s compatibility. The results reveal that RCA has a CBR value of 30.30, compared to 73.23 for SM01 and 49.49 for SM02. These findings suggest RCA has the potential to perform similarly to conventional materials, offering a sustainable alternative for pavement construction while maintaining the required performance standards.
