An Index for Assessing the Environmental Impact of Pavement Maintenance Operations on the Motorway Network: The Environmental Asphalt Rating

In recent years, attention on pavement management is increasing and the research focused development of innovative protocols comparative evaluation maintenance alternatives. Among these, concept sustainability related to pavements gaining ground and, more generally, infrastructure quantification environmental impact as a combination emissions energy consumption. To properly estimate different interventions, calculation methodology presented in this paper that can summarize all aspects for both production paving phases asphalt mixtures. The approach takes into account also need evaluate new methodologies processes order compare these technologies with already used materials processes. result dimensionless index based Environmental Product Declaration (EPD) certification which has been named Asphalt Rating (EAR) weighting factors performance coefficients fine-tuned European scenario. EAR computation wants be certified procedure ensuring repeatability quality but able include noise mechanical characteristics pavement. Several applications are expected such design stage operations, awarding criteria tenders monitoring interventions.
