Abstract

With the goal of "double carbon" and the promotion of ecological civilization construction, the concept of green construction is gradually applied to municipal road engineering, aiming at solving the problems of resource waste and environmental pollution brought by traditional construction mode. This paper discusses the application of green construction technology in municipal road engineering and analyzes its economic benefits. First of all, the paper combs the key technologies such as energy saving, environmental protection materials, water saving and environmental protection and intelligent management, and focuses on the technological principles and applicable scenarios of warm mix asphalt and recycled aggregate concrete. Secondly, based on the life cycle cost method (LCC), an evaluation model including initial investment, operation and maintenance, and environmental governance costs is established, and the key variables are identified through sensitivity analysis. Finally, taking a municipal road project as an example, the cost-benefit difference between traditional and green construction schemes is compared, and the economic feasibility of green construction scheme is verified. The research results show that, although the initial investment of the green construction scheme is high, by reducing the long-term operation and maintenance costs and the external environmental costs, it can produce remarkable economic benefits in the whole life cycle of the project and has good environmental benefits. This study provides theoretical basis and practical reference for promoting the application of green construction technology in municipal road engineering.
