Recycled coarse aggregate (RCA) is a viable substitute for NCA in concrete production, obtained through the recycling of construction and demolition waste (C&DW) [15].It can significantly mitigate the demand for fresh resources and substantially curtail CO 2 emissions in comparison to the extraction of NCA. However, owing to the potential presence of residual …

has shown that aggregate gradation is more impor-tant than aggregate size in ensuring stone-on-stone contact of the larger aggregate particles. For example, Kandhal & Cooley Jr. (2002) tested both fine- and coarse-graded asphalt mixtures for their resistance to rutting. Both the 9.5 mm and 19 mm mixtures exhibited good resistance to rutting.
