Abstract

With the acceleration of urbanization, the scale of municipal road and bridge construction continues to expand. The drawbacks of traditional building materials—high energy consumption, severe environmental pollution, and excessive resource depletion—are becoming increasingly apparent. New eco-friendly materials, characterized by low carbon footprint, energy efficiency, recyclability, and superior performance, are gradually emerging as a key development direction in municipal engineering. This paper begins by examining the types and characteristics of new eco-friendly materials, focusing on their practical applications in road and bridge construction. Through case studies, it explores their performance in durability, cost-effectiveness, and environmental benefits. The sustainability of these materials is further evaluated, highlighting technical and institutional challenges in their widespread adoption, while proposing future development trends and research directions. These materials not only enhance the service life and performance of municipal roads and bridges but also effectively reduce carbon emissions and environmental burdens, providing crucial support for advancing green infrastructure development and achieving sustainable urban growth.
