In recent decades, environmental sustainability and circular economy principles have become central elements of contemporary society, significantly influencing the infrastructure sector. Within this framework, several standards and regulations have been developed worldwide to encourage the use of alternative and reclaimed materials in the asphalt industry. In Italy, the Ministerial Decree 05/08/2024 introduced the “Minimum Environmental Criteria” (Criteri Ambientali Minimi, C.A.M.) to guide the road sector towards more sustainable practices by mandating minimum percentages of recovered, recycled, or by-product materials in new asphalt mixtures. In this perspective, the growing use of reclaimed materials in the production of bituminous mixtures for road pavements is gaining relevance: among these, RAP (Reclaimed Asphalt Pavement) and recycled plastics play a leading role.
