Special Issue Information

Dear Colleagues,

The world is experiencing a degree of rapid urbanization, population growth, rise in the standards of living, and industrialization that is putting severe strain on the resources needed to create new infrastructure systems such as roads, bridges, housing, airports and seaports, sewer systems, and power/energy supply to support these global changes.  The United Nations Department of Economic and Social Affairs estimates that based on current trends, the rate of extraction of natural resources will reach 190 billion metric tons by 2060. This excessive material consumption poses a threat not only to the environment but will also lead to a massive depletion of construction materials, which is particularly more severe in countries with high and booming activities in the construction industry, like India and China. Researchers are exploring the use of artificial intelligence and other modern tools and techniques that allow for the appropriate proactive actions in design, construction techniques, new and smart materials, etc., to be taken to design, construct, maintain, preserve, and sustain these infrastructure systems. There is also a need to develop predictive models for use in the management of infrastructure assets to include the effects of various levels of natural disasters. This Special Issue calls for technical articles that address these critical issues and feature state-of-the-art research on the following topics:

  • Integrating resilience and reliability concepts into design practices;
  • Infrastructure planning and programming;
  • Sustainable construction techniques;
  • Smart construction materials;
  • Infrastructure systems analysis and monitoring;
  • Strategic infrastructure planning and construction under climate change;
  • Green infrastructure designs to meet social, economic, and environmental objectives;
  • Sustainable funding mechanisms for infrastructure development and maintenance.

We look forward to receiving your contributions.

In Brazil, the maintenance and expansion of the federal road network conflict with the country’s climate neutrality goals. The National Department of Transportation Infrastructure (DNIT), responsible for Brazil’s federal highways, lacks tools to assess and mitigate greenhouse gas (GHG) emissions from its projects, which can be achieved through the life cycle assessment (LCA) methodology. Additionally, the scarcity and insufficient quality of environmental data on Brazilian road materials led to using foreign databases in LCA studies conducted in Brazil, generating uncertainties in the results. This research aims to apply LCA to analyze the GHG emissions from highway projects developed by DNIT. The analysis covers the phases of material production, transportation, and construction. Additionally, this study investigates the influence of the leading project disciplines on the results and the differences in outcomes resulting from the use of local Portland cement compared to its equivalent produced in the United States of America (USA) and Europe. The results indicate that the materials production phase has the most significant impact on the project’s global emissions, contributing over 78% in all scenarios. The transportation phase accounts for more than 16% of global emissions, with the potential for greater contributions depending on project transportation distances. Environmental data showed that foreign cement increased the project’s global emissions by 7.31% (Europe) and 12.91% (USA), with the most significant differences observed in pavement disciplines. In all scenarios, the discipline of new pavement presented the highest unitary emissions, followed by the discipline of restored pavement, which showed average values 58% lower than the former, and earthworks. Other services, drainage, and special structures disciplines showed minimal influence on the results. In conclusion, this research proposes an approach to estimate the environmental impact of Brazilian federal highway projects, enabling early mitigation of GHG emissions during the design phase, focusing on critical disciplines and materials, and highlighting potential distortions associated with the use of environmental data from foreign cement in LCA studies of Brazilian highways. Finally, considerations are presented regarding improving and expanding the scope of the calculation methodology used in this study, allowing for a more comprehensive and accurate analysis of the environmental impacts associated with the Brazilian federal road network.
