The environmental impact of the HMAs can be quantitatively analyzed using mid and end point impact indicators as specified in relevant standards and previous studies [75][76][77]. This study primarily focused on midpoint indicators cumulative energy demand (CED), global warming potential (GWP-100), acidification potential (AP), eutrophication potential (EP) and photochemical smog potential (PSP) impacts, which are measured in units of MJ, kg CO 2 eq., kg SO 2 eq., kg N eq., kg O 3 eq., respectively.…”

The conversion of solid waste materials into cleaner products for road paving. applications appears to be a promising and sustainable option. However, there is still a lack of attention given to quantifying the potential environmental benefits of recycling solid wastes in asphalt pavements, regarding the impact on asphalt performance. To address this gap, the present study investigates the effects of recycling electric arc waste based geopolymers on asphalt binder and mixture characteristics, as well as environmental outputs. For this purpose, geopolymers were incorporated into both neat and SBS-modified binders. A comprehensive rheological investigation was conducted using cutting-edge multiple stress creep recovery (MSCR) and linear amplitude sweep (LAS) analyses. Stability, Marshall quotient, and flow values, as well as dry and wetconditioned tensile strength were considered, to determine asphalt mixture properties. In the Life Cycle Assessment (LCA), greenhouse gases resulting from fuel and energy consumption in each inventory phase were determined. The varying service lifetimes, maintenance and rehabilitation plans, and production and construction requirements of the different asphalt schemes were taken into account. Subsequently, the environmental impacts of the asphalt mixtures, including global warming potential, acidification, eutrophication, and smog formation potential, along with the total energy demand, were calculated across different stages of the LCA. The results show that the geopolymerization process results in important contributions in terms of both environmental savings and pavement performance.

“…Then, the main explanatory variables of the maintenance alternatives required careful and broad data collection. All the data related to the application of the present methodology to a case study are collected in the Supplementary Materials as follows: Tables S1 and S2 collect the mix composition data of the asphalt mixtures under analysis, respectively, for the binder and base layers; Table S3 collects the asphalt stiffness moduli at the service temperature used for pavement design; more on the experimental mix design procedure and performance characterization of the asphalt mixtures under analysis can be found in Oreto et al [ 51 ] and Russo et al [ 52 ]; Table S4 collects all the available data regarding the road category, the AADT and the expected number of ESALs in 20 y for the case study under analysis, on which pavement design was based; Table S5 summarizes the results in terms of the type of maintenance intervention, expected frequency of intervention and materials involved; Table S6 collects all the data sources and relative survey year of LCA data; Table S7 summarizes all the cost items of the alternative maintenance strategies; Table S8 reports the final decision matrix of the case study. …”

The latest developments in the field of road asphalt materials and pavement construction/maintenance technologies, as well as the spread of life-cycle-based sustainability assessment techniques, have posed issues in the continuous and efficient management of data and relative decision-making process for the selection of appropriate road pavement design and maintenance solutions; Infrastructure Building Information Modeling (IBIM) tools may help in facing such challenges due to their data management and analysis capabilities. The present work aims to develop a road pavement life cycle sustainability assessment framework and integrate such a framework into the IBIM of a road pavement project through visual scripting to automatically provide the informatization of an appropriate pavement information model and evaluate sustainability criteria already in the design stage through life cycle assessment and life cycle cost analysis methods. The application of the proposed BIM-based tool to a real case study allowed us (a) to draw considerations about the long-term environmental and economic sustainability of alternative road construction materials and (b) to draft a maintenance plan for a specific road section that represents the best compromise solution among the analyzed ones. The IBIM tool represents a practical and dynamic way to integrate environmental considerations into road pavement design, encouraging the use of digital tools in the road industry and ultimately supporting a pavement maintenance decision-making process oriented toward a circular economy.

“…One of the main topics today is to mitigate climate change effects associated with the construction of asphalt pavements; in addition, a rational design of pavement superstructures must be followed integrating the mechanical performance with social-economic and sustainable aspects. The application of life cycle assessment methodology can help to highlight the real benefits of each solution beyond the technical performance required [1].…”

Not all waste is completely burned by waste-to-energy plants. About 73% of it is bottom ashes (BA). Sustainable reuse of the BA is to reprocess them into the production chain of the asphalt mixtures for road pavements. This research deals with an experimental investigation of the mechanical performance of hot and cold asphalt mastics made with the BA filler versus the traditional ones containing limestone powder (LP). First, environmental compatibility tests were carried out and then a rheological analysis, applying viscosity, frequency sweep, and multiple stress creep and recovery tests, was performed to check the feasibility of using the BA as a filler for asphalt-based materials. Looking at the main results, the ecotoxicological tests in terms of EC50 for toxicity on Daphnia and EC50 for algal growth inhibition confirmed the usability of all the mastics from an environmental point of view. The rheological results showed higher G* values for cold asphalt mastics made up with the BA compared to the corresponding solutions made with the LP. Additionally, it was also observed that the mastics containing BA returned a 90% decrease in non-recoverable creep compliance at test temperatures over 40°C compared to the corresponding mastics made with the LP.
