[0002] Energy and environmental issues are becoming increasingly severe. In the field of roads, asphalt pavement regeneration technology can recycle and utilize old pavement materials to a large extent, greatly reducing energy consumption and gas emissions during pavement construction, and achieving good economic and social benefits. However, less attention is paid to energy consumption and greenhouse gas emissions during the regeneration process. The environmental impact caused by pavement regeneration is often ignored, and the environmental impact assessment of regeneration technology is relatively vague, which is not conducive to the advancement of environmental impact research in the field of regenerated road construction. Therefore, in order to further improve the low-carbon and environmentally friendly regenerated asphalt pavement construction model with energy conservation and emission reduction as the main feature, and to promote production enterprises and management departments to pay attention to energy conservation and emission reduction issues, it is necessary to establish a regenerated asphalt pavement energy conservation and emission reduction analysis and evaluation system with energy consumption and emission quantitative analysis as the core.

[0025] The overall idea of the problem in the embodiment of this application is as follows:
[0026] When the asphalt pavement to be regenerated is repaired by the thermal regeneration process, the energy consumption and emission data of the regeneration period of the asphalt pavement to be regenerated is obtained, and the data are analyzed separately to obtain the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index, and construction energy consumption emission evaluation index of the asphalt pavement to be regenerated.

[0027] See also Figure 1The embodiment of the present invention provides a technical solution: a quantitative analysis and evaluation method for energy conservation and emission reduction of regenerated asphalt pavement, comprising the following steps: when the asphalt pavement to be regenerated is repaired by a thermal regeneration process, the regeneration cycle energy consumption and emission data of the asphalt pavement to be regenerated are obtained, and the regeneration cycle energy consumption and emission data include production energy consumption and emission data, transportation energy consumption and emission data, and construction energy consumption and emission data; data analysis is performed on the regeneration cycle energy consumption and emission data of the asphalt pavement to be regenerated to obtain the production energy consumption and emission evaluation index, transportation energy consumption and emission evaluation index, and construction energy consumption and emission evaluation index of the asphalt pavement to be regenerated, and a comprehensive analysis is performed to obtain the comprehensive energy consumption and emission evaluation index of the asphalt pavement to be regenerated; the comprehensive evaluation index of the asphalt pavement to be regenerated is compared and analyzed with a preset comprehensive evaluation index threshold; if the comprehensive evaluation index of the asphalt pavement to be regenerated is lower than the preset comprehensive evaluation index threshold, the abnormal evaluation index is identified, and corresponding optimization measures are taken; if the comprehensive evaluation index of the asphalt pavement to be regenerated is not lower than the preset comprehensive evaluation index threshold, no optimization measures are taken.
[0028] The specific formula for calculating the comprehensive energy consumption and emission evaluation index of the asphalt pavement to be recycled is as follows: Among them, ZhP is the comprehensive energy consumption emission evaluation index of the asphalt pavement to be regenerated, ZpN is the production energy consumption emission evaluation index of the asphalt pavement to be regenerated, α1 is the production coefficient stored in the database, YsP is the transportation energy consumption emission evaluation index of the asphalt pavement to be regenerated, α2 is the transportation coefficient stored in the database, SgP is the construction energy consumption emission evaluation index of the asphalt pavement to be regenerated, α3 is the construction coefficient stored in the database, η is the interaction coefficient stored in the database, α1+α2+α3=1.
[0029] It needs to be explained that the term η*ZpN*YsP*SgP in the formula is used to adjust the superposition effect of the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index and construction energy consumption emission evaluation index of the regenerated asphalt pavement to prevent the comprehensive energy consumption emission evaluation index from being too high or too low.
[0030] And η can be obtained through the following steps: using historical data, combined with the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index, and construction energy consumption emission evaluation index indicators, statistical regression analysis is carried out to quantify the specific impact of each factor on the comprehensive energy consumption emission evaluation index after superposition, so as to fit the initial weight value. Secondly, the sensitivity analysis method is used to adjust the value range and observe its impact on the comprehensive energy consumption emission evaluation results to ensure the stability and rationality of the model.
[0031] α1, α2, and α3 can be obtained through the following steps: read the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index, and construction energy consumption emission evaluation index of the asphalt pavement to be regenerated, and perform sum analysis to obtain a comprehensive evaluation value, and perform a proportion analysis on the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index, and construction energy consumption emission evaluation index of the asphalt pavement to be regenerated and the comprehensive evaluation value, respectively, and use the proportion analysis results as the corresponding coefficients.
[0032] The specific implementation example of calculating the comprehensive energy consumption and emission evaluation index of the asphalt pavement to be regenerated is as follows, and the following data are available:

[0040] Substituting the above data into the specific formula of the comprehensive energy consumption and emission evaluation index of the asphalt pavement to be recycled, we get:
[0041] Comprehensive energy consumption and emission evaluation index of asphalt pavement to be recycled
[0042] =exp((0.34*1.62+0.27*1.26+0.39*1.83) / (0.86*1.62*1.26*1.83))≈1.55.

The construction energy consumption and emission data include construction equipment power, construction equipment operating time value, construction area value, construction compaction efficiency index, construction energy consumption value (consistent with the steps for obtaining the production energy consumption value), construction emission pollution index (consistent with the steps for obtaining the transportation emission pollution index), construction air fluidity value, and construction combustion efficiency value.
[0044] Among them, the production energy consumption value is the sum of all energy consumption used in the production process, such as: the sum of energy consumption in terms of electricity consumption (obtained from the electricity meter), fuel consumption (obtained from the fuel flow meter), and heat energy consumption (obtained from the heat energy meter) (converted into units and then accumulated).
[0045] The total production value is the total amount of the product produced (ie, the final asphalt product used to repair the road surface), which can be obtained through the production records stored in the database.
[0046] The raw material distribution index is the uniformity of the particle size distribution of raw materials (such as aggregates, powders, asphalt, etc.), which can be obtained by sampling, that is, a certain number of samples are randomly selected multiple times and put into a laser particle size analyzer (laser beam irradiates particles, particles and beams scatter, and the angle and intensity of scattered light are used to infer the size of particles) for detection, and automatically calculate and generate D10 (10% of the particles have a particle size less than or equal to D10, and D10 represents the maximum particle size of fine particles in the material), D50 (same as D10), D90 (same as D10) particle size index. And perform weighted processing, perform average processing based on the weighted processing results of each sampling point, and the result is the parameter.

[0054] The transport pollution emission index is the emission level of polluting gases (such as carbon dioxide, nitrogen oxides, and particulate matter) generated during the transportation process. The emission of each polluting gas is weighted, and the result is this parameter.
[0055] The transport engine efficiency value is an average value of the efficiency of the engine of each vehicle in converting the chemical energy of the fuel into mechanical energy (for driving the vehicle), and the transport engine efficiency value of each vehicle can be obtained through the engine specifications stored in the database.
[0056] The transport engine load index is the average of the working intensity of each vehicle during the transport process, and the working intensity of each vehicle = actual output power (consistent with the method of obtaining the transport fuel consumption rate value) / maximum output power (which can be obtained through the engine specifications stored in the database).

[0061] The construction area value can be obtained through the design documents of the construction project stored in the database.
[0062] The construction compaction efficiency index is the deviation between the compaction times of the roller and the theoretical optimal times, that is, the construction compaction efficiency index = (reference compaction times * reference single compaction time) / (actual compaction times * actual single compaction time), and the reference compaction times and reference single compaction time can be obtained through the construction specifications stored in the database, and the actual compaction times and actual single compaction time can be obtained through the on-site construction records stored in the database.
[0063] The construction combustion efficiency value is the average efficiency of all construction equipment (such as diesel rollers, pavers, etc.) in converting fuel combustion into mechanical energy during the construction process. The efficiency of each construction equipment in converting fuel combustion into mechanical energy can be obtained through the equipment's built-in combustion efficiency monitoring system.

[0071] It should be explained that φ1 and φ2 can be obtained through the following steps: Based on historical data, the initial impact weights of the raw material particle size distribution index and the production equipment wear index on the production energy consumption index are determined through statistical regression analysis. Then, based on the sensitivity analysis technology, the value range of the corresponding coefficients under different environmental scenarios is adjusted to ensure the applicability of the formula to a variety of production environments. Subsequently, the model is calibrated through scenario analysis to optimize the rationality and stability of the parameter values.
[0072] β1, β2, and β3 can be obtained through the following steps: obtain historical data, determine the initial impact weights of each variable (such as production energy efficiency index, regeneration agent addition value, production emission index) on the production energy consumption emission evaluation index through statistical regression analysis, and then use the sensitivity analysis method to adjust the value range of the coefficient to evaluate the stability and applicability of these parameters to the formula output. Next, further fit the weights through model optimization (such as machine learning algorithm) to ensure that the formula can accurately reflect the evaluation results of production energy consumption emissions, and fine-tune the coefficients based on the characteristics of different regions to ensure that they are suitable for specific ecological environmental assessment needs.
[0073] δ1 and δ2 can be obtained through the following steps: Based on historical data, the initial impact weight of the production energy efficiency index and the production emission index combined on the production energy consumption emission evaluation index is determined through statistical regression analysis, and then the value range of the coefficient is adjusted using the sensitivity analysis method to evaluate the stability and applicability of these parameters to the formula output.
[0074] In this implementation scheme, by incorporating the wear index, emission index and other key factors (such as raw material particle size distribution, regeneration agent addition amount, etc.) of the production equipment into the comprehensive analysis, the energy efficiency and emission of the production process can be quantified more accurately. Specifically, the impact of equipment wear is quantified separately, and the calculation of emissions is standardized to ensure that the evaluation results are not interfered by extreme values or abnormal values, thereby providing more accurate energy consumption and emission data, which in turn helps to evaluate the actual performance of the production process. Secondly, by standardizing, averaging and proportion analysis of key parameters such as production equipment wear, emission index, and raw material particle size distribution, it is ensured that these parameters can adapt to and maintain good comparability under different production environments. In particular, in the adjustment of the wear coefficient and emission coefficient of the production equipment, sensitivity analysis and scenario analysis are used to correct the model parameters, so that they can be flexibly adjusted according to the specific environment, equipment conditions and process changes, thereby improving the applicability and universality of the method. Finally, through the comprehensive analysis of various energy efficiency and emission data, a comprehensive evaluation index of production energy efficiency and emissions can be generated, thereby providing scientific data support for decision makers, thereby improving production efficiency, reducing energy waste and environmental pollution, and thus improving overall production benefits.

[0076] Among them, the specific formulas for calculating the road energy efficiency correction index, transportation energy efficiency index, transportation emission index, and transportation energy consumption emission evaluation index of the asphalt pavement to be recycled are as follows: Among them, DnX is the road energy efficiency correction index of the asphalt pavement to be recycled, CdL iis the transmission efficiency of the i-th transport vehicle, PdZ is the transport road slope value of the asphalt pavement to be regenerated, ξ is the road slope adjustment coefficient stored in the database, YsH is the transport energy efficiency index of the asphalt pavement to be regenerated, YsL is the transport distance value of the asphalt pavement to be regenerated, RyH is the transport fuel consumption rate value of the asphalt pavement to be regenerated, ZnH is the transport load value of the asphalt pavement to be regenerated, is the road adjustment coefficient stored in the database, YnX is the transportation emission index of the asphalt pavement to be regenerated, YpF is the transportation pollution emission index of the asphalt pavement to be regenerated, λ1 is the transportation pollution adjustment coefficient stored in the database, YdF is the transportation engine efficiency value of the asphalt pavement to be regenerated, λ2 is the transportation efficiency adjustment coefficient stored in the database, YhF is the transportation engine load index of the asphalt pavement to be regenerated, λ3 is the transportation load adjustment coefficient stored in the database, YsP is the transportation energy consumption emission evaluation index of the asphalt pavement to be regenerated, DnX′ is the transportation energy efficiency index of the asphalt pavement to be regenerated after normalization, YnX′ is the transportation emission index of the asphalt pavement to be regenerated after normalization, is the transport interaction coefficient stored in the database, QhT′ is the normalized transport climate condition index of the asphalt pavement to be regenerated, is the climate adjustment coefficient stored in the database, SxW′ is the normalized transport driving behavior index of the asphalt pavement to be reclaimed, is the driving adjustment coefficient stored in the database, i=1, 2, 3, ..., i0, i0 is the number of transport vehicles.

Secondly, the sensitivity analysis method is used to adjust the value range of the coefficient and observe its impact on the transport emission assessment results to ensure the stability and rationality of the model. Based on regional characteristics and actual conditions, the preliminary fitted coefficients are corrected and optimized to finally determine the coefficient value applicable to a specific area.

[0081] In this implementation plan, by comprehensively considering multiple factors (such as transmission efficiency, road slope, transportation distance, load, fuel consumption, etc.), the energy efficiency level of transportation can be more accurately evaluated, and its emissions can be further analyzed, which will help identify energy efficiency bottlenecks and emission sources in the transportation process, thereby providing more accurate data support for subsequent optimization measures. Through comprehensive analysis of factors such as road energy efficiency correction index, transportation fuel consumption rate, and vehicle load, adjustments and corrections can be made according to different transportation environments. For example, the impact of road slope on transportation energy efficiency may vary depending on regional differences. Through regression analysis and sensitivity analysis of historical data, these systems can be flexibly adjusted. numbers, thereby ensuring the adaptability of the model in different regions and conditions, and thus being able to be widely used in different transportation scenarios with strong flexibility. At the same time, it not only considers the impact of a single factor on transportation energy efficiency, but also further captures the interaction between different factors through interaction coefficients, driving behavior adjustment coefficients, etc., and by optimizing the combination of these factors, it can provide more accurate strategies for energy efficiency optimization and emission control in the transportation process. Finally, by using historical data, regression analysis and sensitivity analysis, it can provide a scientific basis for optimal decision-making in the transportation process, thereby reducing unnecessary energy consumption and emissions, reducing overall transportation costs, and improving the transparency and feasibility of decision-making.
[0082] Specifically, the specific steps for obtaining the construction energy consumption and emission evaluation index of the asphalt pavement to be regenerated are as follows: obtain the rated power of the construction equipment and the reference time value of the construction equipment operation of the asphalt pavement to be regenerated; and conduct a comprehensive analysis on the construction equipment power, the construction equipment operation time value, the construction area value, the construction compaction efficiency index, the construction energy consumption value, the rated power of the construction equipment and the reference time value of the construction equipment operation of the asphalt pavement to be regenerated to obtain the construction energy efficiency index of the asphalt pavement to be regenerated; standardize the construction emission pollution index, the construction air fluidity value and the construction combustion efficiency value of the asphalt pavement to be regenerated; conduct a comprehensive analysis based on the construction emission pollution index, the construction air fluidity value and the construction combustion efficiency value of the regenerated asphalt pavement after the standardized treatment to obtain the construction emission index of the asphalt pavement to be regenerated; and normalize the construction energy efficiency index and the construction emission index of the asphalt pavement to be regenerated; and conduct a comprehensive analysis on the normalized construction energy efficiency index and the construction emission index of the asphalt pavement to be regenerated to obtain the construction energy consumption and emission evaluation index of the asphalt pavement to be regenerated.
[0083] The rated power of the construction equipment is the average of the rated power of all the construction equipment during the construction process, and the rated power of each construction equipment can be obtained through the equipment specification sheet stored in the data volume.
[0084] The reference operation time value of the construction equipment is the average of the reference operation time values of all the construction equipment during the construction process, and the reference operation time value of each construction equipment can be obtained through the equipment specification sheet stored in the data volume.

[0086] It needs to be explained that the term τ4*GwZ′*KqL′*SrX′ in the formula is used to adjust the construction emission pollution index, construction air fluidity value, and construction combustion efficiency value to avoid the construction emission index being too high or too low.
[0087] θ1, θ2, θ3, and θ4 can be obtained through the following steps: Based on historical data, the initial impact weight of each variable on the construction energy efficiency index is determined through statistical regression analysis. Then, the range of coefficients is adjusted using the sensitivity analysis method to evaluate the stability and applicability of these parameters to the formula output. Next, the weights are further fitted through model optimization (such as machine learning algorithms) to ensure that the formula can accurately reflect the actual construction energy efficiency. The coefficients are fine-tuned based on the characteristics of different regions to ensure that they are suitable for specific ecological and environmental assessment needs.
[0088] τ1, τ2, τ3, and τ4 can be obtained through the following steps: using historical data, evaluating the influence of each variable on the construction emission index through statistical modeling and regression analysis, and fitting the initial weight values, then adjusting the value range of these coefficients based on sensitivity analysis to ensure that the formula has good adaptability to changes in construction emissions under different environmental conditions, and then using scenario simulation technology (such as prediction models for different pollution emission levels) to further optimize the applicability of the coefficients, and reasonably modify the weight coefficients according to the specific regions and pollution source characteristics.

[0090] In this implementation plan, by comprehensively analyzing multiple variables such as the power, operating hours, and construction area of construction equipment, the energy efficiency and emission performance during the construction process can be accurately evaluated to ensure that the impact of each factor is fully considered, thereby obtaining a more accurate construction energy efficiency and emission index. Secondly, regression analysis, sensitivity analysis and other techniques are used to adjust and optimize coefficients in combination with regional characteristics to ensure that the construction energy efficiency and emission evaluation method can adapt to different environmental conditions. For example, different construction sites may face different factors such as temperature, humidity, and terrain, which will affect the construction energy efficiency and emissions. By flexibly adjusting the coefficients, the evaluation method can have strong environmental adaptability, thereby being able to be used in different environments. It is effectively applied in construction projects. Then, by standardizing the construction emission pollution index, air mobility, combustion efficiency and other data and further normalizing them, the impact of data of different magnitudes can be eliminated, so that the energy efficiency and emission index can be compared on the same scale, thereby ensuring the accuracy of construction energy efficiency and emission control, and then helping to formulate more scientific and accurate energy-saving and emission reduction measures. Finally, through accurate energy efficiency and emission assessments, the energy use and pollution emissions in the construction process can be promoted in a more sustainable direction. Through monitoring and evaluation, the energy consumption and emissions in the construction can be continuously improved, thus laying the foundation for long-term environmental protection and energy utilization efficiency improvement in the construction process.
[0091] Specifically, the specific steps of identifying abnormal evaluation indexes and taking corresponding optimization measures are as follows: the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index, and construction energy consumption emission evaluation index of the asphalt pavement to be regenerated are respectively compared with the preset production energy consumption emission evaluation index threshold, transportation energy consumption emission evaluation index threshold, and construction energy consumption emission evaluation index threshold for judgment and analysis; if the production energy consumption emission evaluation index of the asphalt pavement to be regenerated is lower than the preset production energy consumption emission evaluation index threshold, the production energy consumption emission evaluation index is marked as an abnormal evaluation index, and production optimization measures are taken (i.e., providing optimization equipment to relevant personnel, checking production equipment, etc.). The energy efficiency status of the equipment, whether there are problems such as equipment aging and severe wear, and equipment repair or replacement according to the equipment wear index; improve the energy efficiency of the production process, optimize the production process, and reduce unnecessary energy consumption. For example, optimize the efficiency of heating and mixing; adjust the use of raw materials, check the particle size and ratio of raw materials, optimize the batching process, and reduce energy consumption in production). If the transport energy consumption emission evaluation index of the asphalt pavement to be recycled is lower than the preset transport energy consumption emission evaluation index threshold, the transport energy consumption emission evaluation index will be marked as an abnormal evaluation index, and production optimization measures will be taken (i.e., provide optimized transportation routes to relevant personnel, use GIS to optimize the transportation route, and use GIS to optimize the transportation route). Technology optimizes transportation routes, reduces transportation time and distance, reduces energy consumption during transportation, selects relatively flat and barrier-free roads, and reduces fuel consumption of vehicles during transportation; improves energy efficiency of transportation equipment, uses low-emission and energy-saving transportation vehicles, such as electric or hybrid vehicles, to reduce fuel consumption and pollutant emissions; strengthens driving behavior management, analyzes drivers' driving behavior through data recording and real-time monitoring, and avoids bad behaviors such as sudden acceleration and sudden braking); if the construction energy consumption emission evaluation index of the asphalt pavement to be recycled is lower than the preset construction energy consumption emission evaluation index threshold, the production energy consumption emission evaluation index will be marked as Abnormal evaluation index, and take production optimization measures (i.e. provide optimized construction equipment and technology to relevant personnel, check the energy efficiency and emissions of construction equipment, and maintain, repair or replace the equipment in a timely manner; improve construction efficiency, optimize construction plans, and reduce energy consumption in construction, for example, improve construction compaction efficiency and reduce construction time through more efficient compaction equipment; optimize fuel use and emission control, check the types of fuel used in the construction process, and gradually transition to low-pollution, low-energy consumption environmentally friendly fuels; improve air flow during construction, optimize ventilation conditions on the construction site, improve air flow, and reduce suggestions on harmful gas concentrations).
[0092] In this implementation plan, by comparing and analyzing the production energy consumption emission evaluation index, transportation energy consumption emission evaluation index, and construction energy consumption emission evaluation index of the asphalt pavement to be recycled with the corresponding preset thresholds, it is possible to accurately identify whether there is low energy efficiency, excessive emissions or other abnormal conditions in each link, which is helpful to discover potential problems and avoid long-term resource waste and environmental impact caused by untimely adjustments. Secondly, this step clearly stipulates specific optimization measures to solve problems in specific links in a targeted manner, thereby improving the overall production, transportation and construction efficiency. At the same time, by optimizing the energy efficiency and emissions in the three aspects of production, transportation and construction, it can greatly reduce energy consumption and pollutant emissions, thereby improving the impact of the overall construction process on the environment, thereby ensuring compliance with environmental protection requirements, thereby improving the energy saving level of each link, reducing energy waste, and promoting the development of green construction. Finally, energy efficiency improvement and emission reduction are not only beneficial to the environment, but also can effectively reduce the operating cost of the project. The optimized production and construction process will reduce the consumption of resources such as energy and fuel, thereby reducing the cost of the overall project, especially in the transportation link. By optimizing the route and improving the energy efficiency of transportation vehicles, a large amount of fuel costs can be saved, thereby improving the overall economic benefits.

[0094] In summary, this application has at least the following effects:
[0095] By conducting a detailed quantitative analysis of the energy consumption and emission data of each link in the recycled asphalt pavement, the energy efficiency status and emission level of each link can be accurately quantified. Through comprehensive analysis and comparison with preset thresholds, abnormal evaluation indexes can be accurately discovered, so that targeted optimization can be carried out on the links with problems, thereby reducing energy consumption and greenhouse gas emissions, and reducing the environmental burden during the construction process. For example, in the analysis of the amount of regeneration agent added and the wear index of production equipment, it can provide a specific basis for improving the energy efficiency of the production link and avoid excessive consumption and emissions.
[0096] By tracking and comparing energy consumption and emissions at each stage of the life cycle in detail, we can accurately identify energy efficiency issues that exceed preset thresholds, thereby preventing waste of resources due to unreasonable operations. Through precise energy conservation and emission reduction quantification and optimization adjustments, we can effectively avoid high-energy consumption and high-emission operations that do not meet environmental protection requirements, thereby ensuring that each stage operates within a reasonable energy efficiency range, thereby effectively reducing environmental pollution.
[0097] During the implementation process, the comprehensive energy consumption and emission evaluation index is compared with the preset threshold to identify abnormal links and proactively initiate optimization measures, so that fine-tuned adjustments can be made to specific problems, thereby improving the immediate response capability of energy conservation and emission reduction, and enabling the optimization measures to be accurately and efficiently implemented, thereby improving the energy-saving effect of the overall project.
[0098] Through precise data analysis and optimization measures, we can significantly improve resource utilization efficiency and reduce the overall cost of the project. Based on various modules, we can comprehensively collect and analyze energy consumption and emission data in each link, identify specific energy-saving potential, and reduce operating costs, thereby improving economic benefits, and effectively reducing greenhouse gas and pollution emissions. Without sacrificing project quality, we can reduce excessive use of resources and promote sustainable development.
