<p>Surface dressing is a cost-effective pavement surfacing technique widely used for low- and medium-traffic roads in Morocco, where its performance strongly depends on the quality of the binder–aggregate interaction. This study investigates the potential use of recycled concrete aggregates (RCA), obtained from construction and demolition waste, as a sustainable alternative to natural aggregates in double surface dressing applications. A comprehensive laboratory-based experimental program was conducted to characterize the physical, mechanical, and surface properties of RCA and to evaluate their interaction with a cationic rapid-setting (CRS) bitumen emulsion in accordance with Moroccan and European standards. Two aggregate size fractions commonly used in surface dressing practice (6.3/10&#xa0;mm and 10/14&#xa0;mm) were examined. The results indicate that the recycled concrete aggregates satisfy most of the specification requirements related to particle size distribution, shape, angularity, fragmentation resistance, wear resistance, and polishing resistance. However, surface cleanliness and binder–aggregate adhesion were found to be below the specified limits, mainly due to the presence of adhered cement mortar on the aggregate surface. These findings highlight the critical role of aggregate surface condition in controlling emulsion breaking and coating efficiency in surface dressing systems. The significance of this study lies in providing the first systematic laboratory evaluation of recycled concrete aggregates for double surface dressing under Moroccan standards and traffic conditions. The outcomes contribute to sustainable pavement engineering by identifying both the technical potential and the key limitations of RCA use in double surface dressing, thereby offering a scientific basis for future optimization strategies and field implementation on low- and medium-traffic roads.</p>
