Abstract


Based on the 2030 Agenda for Sustainable Development (25th September 2015), transport systems have to be 1) Sustainable. 2) Quality and resilient. 3) Safe. To this end, note that the Italian Ministry of Research funded the Research Project PRIN USR342 that involves related ideas and focuses on 3 paving solutions (made with recycled materials and sustainable technologies), 4 sets of modules (software), and 2 platforms. The objective of the study here presented deals with the assessment of the best pavement technology based on energy and environmental performance. Consequently, a life cycle assessment, LCA, was applied, considering material production, construction, maintenance, and end of life. The environmental impact of the different pavement technologies was derived. Results demonstrate that the use of warm mix asphalts and of recycled asphalt pavement (RAP) yields the lowest energy consumption and environ-mental impact. Furthermore, under the hypotheses of the study, the production of mixtures is crucial because it corresponds to a contribution of about 60-70% in the life cycle of the different materials. LCA approach confirms as a methodology able to help decision makers when strategies and actions for the eco-design of road pavements are needed.
