Description

Technical Field

[0001] The present invention belongs to the technical field of construction carbon emission, and in particular relates to a method and system for calculating carbon emission and carbon reduction during highway maintenance and repair construction. Background Art

[0002] The transportation industry is one of the three key areas of energy consumption. How to achieve low-carbon emission reduction in the transportation industry is an important issue in transportation. Therefore, it is of great significance to study the carbon emission calculation method, obtain the exact carbon emissions, study the scheme to reduce carbon emissions, and obtain the carbon reduction benefits to guide the green development during the construction of highways and promote sustainable development in the transition to a low-carbon economy. At present, there have been some studies on the carbon emissions of highways, but these studies mainly focus on the maintenance and construction of roads during operation, the emissions of maintenance building materials, and the carbon emissions of different types of vehicles on highways, but do not calculate the carbon emissions generated by the entire road during the construction process. Therefore, there is an urgent need for an assessment of the calculation method of carbon emissions generated by highways during construction.

[0003] At present, the research on carbon emissions during the operation period of highways mainly focuses on road operations or vehicle carbon emissions. At present, a more popular carbon emission accounting method is that some scholars have studied the carbon emission accounting method and emission reduction technology during the road construction period. Through the inventory-based accounting method, the input-output-based carbon emission accounting method, and the process analysis-based full life cycle evaluation method, technical support is provided for clarifying the carbon emissions during the road construction period and related carbon reduction measures. Although the final carbon emissions calculated by this method are more accurate, it can only be used to calculate carbon emissions when the road is clearly constructed. It is not a universal accounting method and does not take into account that many data cannot be obtained during the actual construction process. And under the condition of missing data, this carbon emission accounting method cannot be used. In addition, some scholars also use the full life cycle evaluation method to determine the emission boundaries and inventory analysis for the road maintenance and operation stages that are more difficult to calculate, determine the carbon emission calculation method for the maintenance projects in these two stages, and establish an asphalt pavement maintenance strategy optimization model with the goal of minimizing carbon emissions. However, this method is relatively general and cannot obtain the specific carbon emissions generated by fossil fuels or construction machinery. It can only perform overall optimization rather than local optimization. It is difficult to optimize carbon reduction during construction. Existing research results are mainly aimed at a certain category of carbon emissions, or more general carbon reduction plans. There is no universal carbon emission accounting method during road construction, nor are there more specific carbon reduction measures and integrated evaluation of their carbon reduction benefits. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the prior art fails to calculate the carbon emissions and carbon reductions generated during the construction of the entire highway to obtain the exact carbon emissions. A method and system for calculating carbon emissions and carbon reductions during highway maintenance and construction is proposed.
