Environmental Benefit Analysis of Resource-saving Rural Road Structure
In order to analyze the environmental benefits of the resource-saving rural road structure,the life cycle assessment(LCA)method was used to compare and research the difference of energy consumption and carbon emission between it and con-ventional pavement structure.The results show that:the main energy consumption and carbon emission generation aspects of road construction is the production of raw materials(including aggregates,asphalt,cement,etc.)and asphalt mixture;the re-source-saving pavement structure can effectively reduce the energy consumption and carbon emissions of pavement construction by 16％to 22％,through reducing the use of raw materials.In order to further reduce the energy consumption and carbon emissions of pavement construction,relevant research about the production of asphalt mixture can be carried out.
