Abstract: The construction industry is a major contributor to global resource consumption and waste generation. Recycled Concrete Aggregate (RCA), produced from demolished concrete structures, offers a sustainable alternative to natural aggregates in pavement construction. This study investigates the mechanical and
durability properties of RCA-based pavement mixtures and evaluates their performance through laboratory testing and life-cycle cost analysis. Results indicate that RCA can partially replace natural aggregates without significantly compromising structural integrity, while contributing to reduced environmental impact. The findings support RCA’s potential as a sustainable material in civil infrastructure projects.
