Abstract
The rapid expansion of transportation infrastructure has significantly accelerated the depletion of natural aggregate resources while generating substantial quantities of construction and demolition (C&D) waste. To promote environmental sustainability and circular economy principles in highway engineering, this study presents a comprehensive experimental evaluation of Recycled Concrete Aggregates (RCA) as a partial and total replacement for Natural Aggregates (NA) in rigid and flexible pavement applications.
