    Pavement construction and maintenance have become very common worldwide as traffic volumes and vehicular axle weights continue to rise as the global population grows and technology advances. The extensive utilization of natural resources implies that their existence for long-term availability cannot be assured. Using materials from the various damaged and collapsed structures will save money and find a solution to the trash disposal issue. These materials have inferior engineering properties compared to conventional materials and cannot be used directly in pavement applications. These materials must be processed or stabilized by mechanical and chemical stabilization techniques. Processing of Recycled Concrete Aggregates (RCAs) has gained more importance in improving the physical properties. In the current investigation, construction and demolition (C&D) waste was processed in two stages successively. In the first stage, C&D waste was subjected to manual crushing and further processed through jaw crushing. The aggregates were processed through ball milling in the second stage. The natural aggregates are entirely replaced with the RCA in cement-treated bases (CTBs) at 3, 5, and 7% stabilization levels. Mechanical and durability properties were evaluated. The RCA produced from the ball milling method performs better than the unprocessed RCA. The mix having 7% cement content with processed RCA met the specifications for CTB. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
