Abstract
<jats:p>This study examines the technical and economic effects of incorporating Reclaimed Asphalt Pavement (RAP) and basalt fiber into asphalt mixtures within the framework of sustainability and circular economy principles. Twelve mixtures with varying RAP (0–45%) and fiber (0–3‰) contents were tested using the Tensile Strength Ratio (TSR) and Hamburg Wheel Tracking methods. Results showed that RAP significantly improved rutting resistance and reduced costs, achieving up to 34% savings at 45% RAP. Although basalt fiber slightly increased initial costs due to higher bitumen demand, it enhanced durability and reduced long-term maintenance needs. Overall, RAP supports circular economy goals by lowering material and energy use, while basalt fiber strengthens mechanical performance, offering a balanced and sustainable pavement solution.</jats:p>
