[0004] Carbon reduction accounting is a method to evaluate the contribution of pavement maintenance construction to reducing carbon emissions. It involves quantifying and monitoring the amount of carbon dioxide and other greenhouse gas emissions reduced by specific activities or measures over a certain period of time. However, in the actual construction process, construction activities are one-time in nature, and require a large number of material types and construction processes. The relevant technology uses factors such as materials, equipment, and fuel consumption throughout the construction phase to simply and directly calculate the overall carbon emissions, and uses the obtained carbon emissions to perform carbon reduction accounting. This makes it difficult to clearly analyze the carbon reduction of specific materials, equipment, and other carbon reduction situations at different levels such as processes and projects during the construction process, and thus it is difficult to provide targeted low-carbon and environmental protection measures at different construction stages.

[0053] like Figures 1 to 3 The carbon reduction accounting method for asphalt pavement maintenance projects shown in the figure includes the following steps:

[0054] Obtain the real-time production list of asphalt pavement maintenance projects based on historical records, analyze the production list, and determine the carbon reduction accounting target range corresponding to the asphalt pavement maintenance projects;

[0055] Determine the time range for carbon reduction accounting based on the construction characteristics of asphalt pavement maintenance projects;

[0056] The types of carbon emissions generated by asphalt pavement maintenance projects are divided according to the carbon emission energy type and generation stage;

[0058] Obtain a baseline emission reduction for the project based on historical carbon emissions from similar asphalt pavement maintenance projects;

[0059] The carbon reduction of the asphalt pavement maintenance project is calculated based on the obtained carbon emissions generated by the asphalt pavement maintenance project and the corresponding project benchmark emission reduction.

[0060] The present invention can accurately reflect the carbon emissions in the actual construction process by recording the production data during the construction process in real time, determine the target range of carbon reduction accounting, provide basic data for subsequent carbon emission accounting, and ensure the accuracy of subsequent carbon reduction accounting; by making a detailed division of carbon emission processes of different types and production stages, it provides an implementation basis for taking targeted carbon reduction measures; by setting the project benchmark emission reduction by comparing historical data, it can accurately evaluate the carbon reduction in the current maintenance construction process, provide a reference basis for carbon reduction accounting, and thus ensure the accuracy and comparability of carbon reduction accounting results of green and low-carbon asphalt pavement maintenance projects.

[0061] It should be noted that, based on the accounting results, corresponding carbon reduction measures can be given for different carbon reduction accounting target ranges, carbon reduction accounting time ranges and carbon emission types, to form scientific and comprehensive support for carbon reduction measures, reduce carbon emissions during the construction process, achieve green and low-carbon maintenance, improve resource recycling efficiency, and promote the green and sustainable development of highway maintenance.

[0062] After the carbon reduction calculation of the asphalt pavement maintenance project is completed, the carbon reduction calculation results of the asphalt pavement maintenance project and the corresponding optimization suggestions can be output and displayed in graphics and text, or generated in the form of a report, so that relevant personnel can intuitively and clearly understand the relevant carbon reduction situation of the asphalt pavement maintenance project.

[0063] Based on the above embodiment, the target range of carbon reduction accounting includes equipment entry and exit processes, raw material production processes, raw material transportation processes, mixture mixing processes, mixture transportation processes, original road surface milling processes, milling material transportation processes, mixture paving processes and mixture rolling processes; by dividing the different processes in the construction process of asphalt pavement maintenance projects, the precise carbon emission data of a single process can be determined, providing data support for subsequent carbon reduction accounting and ensuring the accuracy of the accounting results.

[0064] Based on the above embodiment, the carbon reduction accounting time range starts from the project start time and ends at the project completion time, and the carbon reduction accounting time corresponding to different processes is divided and limited according to the carbon reduction accounting target range; that is, the construction period of the entire asphalt pavement maintenance project can be selected as the carbon reduction accounting time range, the project start time can be determined as the start time of traffic control, and the project completion time can be determined as the time when traffic control is lifted.

By accounting for the carbon emissions generated by the consumption of electricity by construction machinery, it is helpful to determine the impact of electricity use on the overall carbon footprint of the project and provide targeted measures, such as encouraging the use of clean energy electricity, such as wind power and solar energy, to further improve energy efficiency. By evaluating the carbon emissions generated by the consumption of raw materials, the impact of raw material consumption on the environment can be reflected, and the sustainability of raw material selection can be promoted, such as using low-carbon or zero-carbon raw materials and optimizing the production and transportation processes of materials.

[0067] By separately understanding the impact of different carbon emission types on the entire asphalt pavement maintenance project construction process, the accuracy and comprehensiveness of the carbon reduction accounting of the asphalt pavement maintenance project are taken into account, which helps to achieve more effective environmental management and sustainable development goals.

[0072] Based on the above embodiment, the direct carbon emissions generated by the combustion of energy from construction machinery are obtained by the following formula:

[0078] Among them, G2 represents the indirect carbon emissions caused by the electricity consumed by construction machinery, e r represents the total amount of electricity used for the rth carbon reduction accounting target, s r represents the carbon emissions generated by consuming each unit of electricity at the kth carbon reduction accounting target, where k represents the number of the carbon reduction accounting target involving the consumed electricity;

[0079] The carbon reduction accounting targets involving electricity consumption include but are not limited to the equipment entry and exit process, raw material transportation process, mixture mixing process, mixture transportation process, original road milling process, milling material transportation process, mixture paving process and mixture rolling process.

[0080] The indirect carbon emissions due to raw material consumption are obtained by the following formula:

[0081] G3=∑M j ·g j

[0082] Among them, G3 represents the indirect carbon emissions caused by raw material consumption, M j represents the total mass of the jth raw material used, g j It represents the carbon emission generated by producing each unit of the jth raw material, and k represents the number of the raw material type involved in the asphalt pavement maintenance project.

[0083] The types of raw materials involved in asphalt pavement maintenance projects include but are not limited to asphalt, modified asphalt, emulsified asphalt, aggregates, cement, additives, etc.

[0084] It should be noted that the carbon emissions s generated by each unit mass consumed at the kth carbon reduction accounting target k , the carbon emissions s generated by consuming each unit of electricity at the kth carbon reduction accounting target r and the carbon emissions g generated by producing each unit of the jth raw material jIt can be determined by referring to the data in the European Asphalt Association Database, China's Localized LCA Basic Database CLCD and other relevant domestic and foreign databases, or by conducting self-research of relevant materials or calculating unit greenhouse gas emissions. No additional restrictions are made here.

[0085] On the basis of the above embodiment, based on the carbon emissions of similar asphalt pavement maintenance projects in historical records, obtaining the project baseline emission reduction includes the following steps:

[0089] The project baseline emission reduction is a quantitative reference for the carbon reduction measurement of asphalt pavement maintenance projects. It can help determine the carbon emission benchmark for asphalt pavement maintenance projects, thereby measuring the difference between the actual project and the benchmark. By screening the relevant projects in the historical records according to the target range and time range of the carbon reduction accounting for asphalt pavement maintenance projects, similar pavement maintenance projects that meet a certain similarity threshold are selected as references to ensure that the selected historical data is similar to the current project in terms of type, scale, construction conditions, etc., thereby improving the reference value of the benchmark emission reduction. By calculating the specific emissions of each similar maintenance project in different carbon emission types, a data basis is provided for subsequent average value calculations, and project managers are helped to understand the carbon emissions under similar conditions and formulate emission reduction targets and strategies accordingly. This can more scientifically evaluate the carbon emission impact of asphalt pavement maintenance projects and provide data support for achieving more environmentally friendly construction practices.

[0093] By calculating the average value, the impact of abnormal data of a single project on the benchmark emission reduction of the project can be reduced, making the benchmark emission reduction more stable and reliable, facilitating the comparison and analysis of carbon emissions between different similar maintenance projects, and providing a consistent reference for decision-making. The carbon emissions generated by each similar maintenance project corresponding to the carbon emission type G 类似工程 Please refer to the carbon emissions generated by the above asphalt pavement maintenance project G 养护工程 is determined by the way in which it is obtained.
