Abstract:Under the industrial background of the deep integration of quality improvement and efficiency enhancement of stock transportation infrastructure with the "Dual Carbon" strategy, the municipal reconstruction of existing highways has become an important measure to advance the development of new urbanization and perfect the municipal transportation road network. To achieve environmental protection and economic conservation, when old roads are widened and reconstructed, the existing old roads are often used for structural reinforcement and longitudinal section correction, which requires the elevation of the existing pavement to be raised, resulting in a height difference with the surrounding plots. Combined with the S233 Line Fengxi Square - Paofu South Road Section Reconstruction Project, how to achieve good coordination between the elevation of the old road after reconstructed and the current land plot, good environmental benefits and cost savings through refined design is analyzed under the boundary conditions of extreme land use, which provides referenceable experience for the design of similar projects.
