Abstract

This study investigates the performance of recycled concrete aggregates (RCA) in gravel-cement mixtures, focusing on strength, shrinkage, and durability. Key topics include the characterization of RCA, the impact of RCA content on mechanical properties, and the shrinkage behavior of the mixtures. The findings reveal that while higher RCA content reduces compressive, flexural, and indirect tensile strengths, it also decreases shrinkage, enhancing long-term durability. The study concludes that RCA-based mixtures offer a sustainable and cost-effective alternative for road construction, particularly for base layers in low- to medium-traffic roads. The research highlights the potential for significant cost savings and reduced CO₂ emissions, making it a valuable resource for professionals seeking environmentally friendly construction materials.
