With growing concerns over the depletion of natural resources, the use of recycled concrete aggregates (RCA) has gained attention as a sustainable alternative to natural aggregate (NA). While RCA has been widely explored in highway construction, its application in non-bituminous layers of aircraft pavements, including runways, taxiways, and aprons, remain underexplored. This study investigates the feasibility of RCA in these applications through a two-phase approach. In the first phase, laboratory trials were conducted by replacing NA with 100 % RCA in granular sub-base (GSB) and cement treated sub-base (CTSB), and 80 % RCA in wet mix macadam (WMM). These mixes were assessed for mechanical and durability properties to ensure compliance with standard specifications. The second phase involved constructing trial pavement sections using the optimized RCA-based mix designs, followed by field performance evaluations and quality control tests. The results demonstrated that RCA as a granular material meets the ministry of road transport and highways (MORTH) and federal aviation administration (FAA) specifications, ensuring structural adequacy and long-term performance. The trial sections exhibited satisfactory field performance, confirming the feasibility of RCA for sustainable pavement construction. This study highlights RCA as an environmentally friendly and resource-efficient alternative for non-bituminous layers in aircraft pavements. The successful implementation of RCA in such critical infrastructure can significantly contribute to reducing construction waste, conserving natural aggregates, and promoting sustainable construction practices
