The use of Reclaimed Rubberised Asphalt Mixtures (RRAM) in road pavement construction is a significant stride in reducing reliance on new materials and reducing waste disposal. RRAM provides a sustainable, cost-effective solution for roads, boosting durability and performance while supporting environmental causes [1, 2]. However, despite its benefits, challenges remain. A thorough exploration of recycling RAM into RRAM is crucial. This study investigates into this, aiming to evaluate RRAM recyclability through a tailored three-step procedure: 1) laboratory production of RRAM, 2) designing RRAM asphalt mixtures using the SUPERPAVE5 concept, and 3) performance-based characterization of RRAM. This comprehensive approach assesses rutting, cracking, and moisture damage resistance. The results highlight RRAM's potential benefits in road construction, shedding light on its recyclability and paving the way for future sustainability-focused research in road-building practices.

Abstract
The use of Reclaimed Rubberised Asphalt Mixtures (RRAM) in road pavement construction is a significant stride in reducing reliance on new materials and reducing waste disposal. RRAM provides a sustainable, cost-effective solution for roads, boosting durability and performance while supporting environmental causes [1, 2]. However, despite its benefits, challenges remain. A thorough exploration of recycling RAM into RRAM is crucial. This study investigates into this, aiming to evaluate RRAM recyclability through a tailored three-step procedure: 1) laboratory production of RRAM, 2) designing RRAM asphalt mixtures using the SUPERPAVE5 concept, and 3) performance-based characterization of RRAM. This comprehensive approach assesses rutting, cracking, and moisture damage resistance. The results highlight RRAM's potential benefits in road construction, shedding light on its recyclability and paving the way for future sustainability-focused research in road-building practices.
