[0002] With the acceleration of urbanization and the increasing traffic congestion, road maintenance is particularly important as an important infrastructure. Good road conditions can not only ensure traffic safety and reduce traffic accidents, but also improve transportation efficiency and reduce vehicle operating costs and maintenance costs. Therefore, scientific and reasonable road maintenance is of irreplaceable importance to the convenience of daily life.

[0003] At present, common road maintenance technologies mainly rely on regular manual inspections and simple potting glue repair measures. However, this maintenance method has obvious limitations. Manual inspections are difficult to fully and timely detect early road diseases, resulting in many problems not being properly handled in the early stages, thereby aggravating the degree of road damage and increasing the cost of road maintenance. Traditional potting glue is mainly used to fill cracks, lacks improvement in the overall performance of the road and preventive protection, and cannot effectively delay the aging and damage process of the road, resulting in a relatively short service life of the road.

[0016] In order to solve the above problems, the present invention also provides a computer-readable storage medium, in which at least one instruction is stored. The at least one instruction is executed by a processor in an electronic device to implement the above-mentioned road maintenance method based on high-elastic potting glue.

[0017] In order to solve the problems described in the background technology, the present invention first uses satellite imagery to obtain road spectral images, and then performs road aging assessment based on the images, so as to comprehensively and objectively understand the current aging status of the road to be maintained. Compared with the traditional on-site manual inspection method, satellite imagery is not restricted by factors such as terrain and traffic, and can quickly obtain a large amount of road information. The road aging value obtained by spectral image analysis enables maintenance work to take corresponding measures for roads with different degrees of aging, thereby improving the efficiency and effectiveness of maintenance. Then, based on the maintenance cycle, the road environment is predicted to obtain an environmental change coefficient group. This process helps to understand in advance the environmental changes that the road may face in the future. By obtaining these environmental change coefficients, the future damage trend of the road can be more accurately predicted, thereby enhancing the foresight and adaptability of road maintenance. According to the road aging value and the environmental change coefficient group, the road damage prediction is performed to obtain the road damage rate, and it is judged whether it is greater than the standard damage rate. This step realizes the quantitative evaluation of the future damage degree of the road. By comparing with the standard damage rate, It is possible to clearly identify which roads need maintenance. This method avoids the subjectivity and uncertainty of judgment based on experience alone, first protects the roads that are really in urgent need of maintenance, and improves the overall quality of road maintenance and resource utilization efficiency. When it is confirmed that the road damage rate is greater than the standard damage rate, the high-elastic potting glue is modified to obtain an optimized potting glue. This step modifies the traditional potting glue so that the obtained optimized potting glue has better adaptability. Then, based on the road damage rate and the standard damage rate, the coverage thickness and coverage benefit value of the candidate maintenance road are calculated. By calculating the coverage thickness, it can be ensured that an appropriate amount of potting glue is used during the maintenance process, and the calculation of the coverage benefit value quantifies the value of the maintenance work, so that maintenance personnel can clearly understand the input-output ratio of each section of road maintenance, thereby achieving optimal allocation of resources and maximization of maintenance benefits. Then, the candidate maintenance road set is prioritized to obtain a priority maintenance road set. This sorting process enables maintenance work to prioritize those roads with higher coverage benefit values, thereby ensuring that limited maintenance resources can be first invested in the sections that can produce the most significant effects. Finally, the optimized potting glue is used to cover the priority maintenance road set with potting glue. In this step, the potting glue that is traditionally only used to fill cracks is innovatively used in preventive maintenance of roads, so that the roads can be effectively protected before they are seriously damaged, thereby increasing the service life of the roads. Therefore, the present invention can optimize the maintenance efficiency during the road maintenance process and increase the service life of the roads. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1 FIG. 1 is a flow chart of a road maintenance method based on a high-elastic potting compound provided by an embodiment of the present invention. In this embodiment, the road maintenance method based on a high-elastic potting compound includes: S1. Receive a road maintenance instruction, determine a to-be-maintained area based on the road maintenance instruction, and count a set of roads to be maintained in the to-be-maintained area, wherein the set of roads to be maintained includes multiple roads to be maintained, and the road to be maintained is a road section in the to-be-maintained area.

[0024] It can be understood that the road maintenance instruction refers to a manually initiated instruction to perform road maintenance on a specific area, the area to be maintained refers to the specific area included in the road maintenance instruction, and the road set to be maintained refers to a collection of various road sections in the specific area.

[0025] Exemplarily, in area A, there are multiple main roads, multiple secondary roads and multiple branch roads, and these multiple main roads, multiple secondary roads and multiple branch roads constitute the road set to be maintained.

[0026] S2. sequentially extract the roads to be maintained from the set of roads to be maintained, take satellite images of the roads to be maintained to obtain road spectral images, and perform road aging assessment on the roads to be maintained based on the road spectral images to obtain road aging values.

[0027] It should be explained that the road spectral image refers to the spectral image of the road to be maintained, which is taken by a remote sensing satellite. The road spectral image contains multiple image layers, and each image layer has a corresponding band. Since the road reflectivity increases with the degree of road aging, the aging degree of the road to be maintained can be analyzed according to the change of reflectivity of the road to be maintained in different bands. Among them, the road reflectivity refers to the ratio of the luminous flux reflected by the road surface to the luminous flux incident on the road surface. The road reflectivity can be obtained from the spectral image of the road. It can be understood that the road aging value refers to a numerical value that measures the aging degree of the road to be maintained. The higher the aging degree of the road to be maintained, the greater the road aging value.

[0028] In detail, the road aging assessment is performed on the road to be maintained according to the road spectral image to obtain the road aging value, including: Determining a spectral band group in the road spectral image, wherein the road spectral image includes a plurality of spectral image layers, and each spectral image layer corresponds to a spectral band; Extracting spectral bands in sequence from the spectral band group, identifying the road reflectance of the road to be maintained in the spectral image layer corresponding to the spectral bands, and summarizing the road reflectance to obtain a road reflectance group; Acquire a historical spectral image set of the road to be maintained, and identify a significant change band group in the spectral band group based on the historical spectral image set, wherein the significant change band group includes one or more significant change bands; Determine a significantly changed reflectivity group corresponding to the significantly changed band group in the road reflectivity group; The road aging value is calculated based on the group of significantly changing reflectances.

[0029] It can be understood that the spectral band group refers to the combination of all light bands contained in the road spectral image, so the road reflectivity refers to the average reflectivity of the road to be maintained in the spectral image. Since the spectral image includes multiple wavelengths, the reflectivity of the road at each wavelength is different, so the road reflectivity of the number of times is the average value of the reflectivity corresponding to all wavelengths, and the reflectivity mentioned later has the definition of having an average value. The historical spectral image set refers to the set of spectral images of the road to be maintained acquired in the past period. The significantly changed band group refers to a combination of multiple significantly changed bands, and the significantly changed band refers to a spectral band with obvious changes in the spectral band group, wherein the obvious change refers to the standard deviation between the reflectivities corresponding to different wavelengths in the spectral band is greater than the standard deviation threshold. Since there are spectral bands in the spectral band group whose reflectivity changes are not obvious, and the aging information that can be provided by such spectral bands is limited, the aging value is identified only based on the significantly changed bands.

[0030] Furthermore, in order to ensure the accuracy of subsequent reflectivity analysis, the historical spectral image here and the road spectral image are taken under similar lighting conditions and similar environments. For example, if the road spectral image is an image taken on a sunny day, then the acquired historical spectral image should also be an image of the road to be maintained taken on a sunny day.

[0031] In detail, the identifying the significantly changed band group in the spectral band group based on the historical spectral image set includes: Sequentially extracting historical spectral images from the historical spectral image set, wherein the historical spectral images and the road spectral images have the same spectral band group; Based on the spectral band group, identifying the historical reflectance group of the historical spectral image, summarizing the historical reflectance group to obtain a historical reflectance group set, wherein the historical reflectance in the historical reflectance group corresponds one-to-one to the spectral band in the spectral band group; Extracting spectral bands in sequence from the spectral band group, and identifying the same-band reflectance set corresponding to the spectral band in the historical reflectance group set; Calculating the standard deviation of all the same-band reflectances in the same-band reflectance set to obtain the same-band standard deviation, summarizing the same-band standard deviation to obtain a same-band standard deviation group, wherein one same-band standard deviation corresponds to one spectral band; Based on the standard deviation groups of the same bands, the significantly changed band groups are identified in the spectral band groups.

[0032] It can be understood that the historical reflectivity group refers to the combination of reflectivity of each spectral band in the historical spectral image, and the same-band reflectivity set refers to a set of multiple same-band reflectivities, wherein the same-band reflectivity refers to the set of all reflectivities under the spectral band in the historical reflectivity group set, and the same-band reflectivities in the same-band reflectivity set come from different historical reflectivity groups in the historical reflectivity group set. The same-band standard deviation refers to the standard deviation of all same-band reflectivities in the same-band reflectivity set.

[0033] In detail, the method of identifying a significantly changed band group in a spectral band group based on a same-band standard deviation group includes: Setting a standard deviation threshold, and determining whether there is a same-band standard deviation greater than the standard deviation threshold in the same-band standard deviation group; If there is a same-band standard deviation greater than the standard deviation threshold in the same-band standard deviation group, the same-band standard deviation greater than the standard deviation threshold will be recorded as a significant standard deviation; If there is no same-band standard deviation greater than the standard deviation threshold in the same-band standard deviation group, then identify the maximum standard deviation in the same-band standard deviation group, and record the maximum standard deviation as a significant standard deviation; The significant standard deviations are summarized to obtain a significant standard deviation group, and a significant change band group corresponding to the significant standard deviation is determined in the spectral band group.

[0034] It is understandable that the standard deviation threshold refers to an artificially set constant, but when the standard deviation of the same band is greater than the standard deviation threshold, the corresponding spectral band can be artificially regarded as a band with obvious changes, that is, a band with significant changes.

[0035] In detail, the calculating of the road aging value according to the significantly changed reflectivity group includes: Extracting significantly changed reflectances in the significantly changed reflectance group in sequence, and determining significantly changed bands corresponding to the significantly changed reflectances; Draw a reflectivity-wavelength curve of the significantly changed wavelength band, wherein the reflectivity-wavelength curve is a curve showing that the reflectivity changes with the wavelength, and the horizontal axis of the reflectivity-wavelength curve is the wavelength, and the vertical axis is the reflectivity; Determine a first-order derivative curve of the reflectivity wavelength curve, wherein the horizontal axis of the first-order derivative curve is the wavelength, and the vertical axis is the first-order derivative of the reflectivity with respect to the wavelength, and discern a change trend of the first-order derivative curve, wherein the change trend includes: an increasing trend and a decreasing trend; If the change trend of the first-order derivative curve is an increasing trend, the significantly changed reflectivity is recorded as a promoted reflectivity; If the change trend of the first-order derivative curve is a downward trend, the significantly changed reflectivity is recorded as the suppressed reflectivity; The promoted reflectivity and the suppressed reflectivity are respectively summarized to obtain a promoted reflectivity group and a suppressed reflectivity group. Based on the promoted reflectivity group and the suppressed reflectivity group, the road aging value is calculated using the following formula: ; in, Indicates the road aging value, represents the number of promoted reflectances in the promoted reflectance group, Represents the first A boost in reflectivity, represents the number of suppressed reflectances in the suppressed reflectance group, Indicates the first The suppression reflectivity, It represents the sum of all the promoted reflectances in the promoted reflectance group and all the suppressed reflectances in the suppressed reflectance group.

[0036] It can be understood that the significantly changed band refers to the spectral band corresponding to the significantly changed reflectance, the reflectance wavelength curve is the relationship curve between the reflectance and wavelength corresponding to each wavelength in the significantly changed band, the horizontal axis of the curve is the wavelength, and the vertical axis is the reflectance corresponding to the wavelength, the first-order derivative curve refers to the relationship curve between the first-order derivative of the reflectance and the corresponding wavelength, the growth trend refers to the increase of the first-order derivative of the reflectance with the increase of the wavelength, and the downward trend refers to the decrease of the first-order derivative of the reflectance with the increase of the wavelength.

[0037] It should be explained that, since the changing trends of different parts in different first-order derivative curves may be different, the above-mentioned changing trends are overall changing trends, which are determined artificially.

[0038] S3. Based on a preset maintenance cycle, perform environmental prediction on the road to be maintained to obtain an environmental variation coefficient group, wherein the environmental variation coefficient group includes: a temperature variation coefficient, a vehicle flow variation coefficient, and a rainfall variation coefficient.

[0039] It is clear that the maintenance cycle refers to a time period set artificially, and the purpose of subsequently covering the road to be maintained with sealing glue is to prevent the road to be maintained from being damaged during the maintenance cycle. Since temperature, traffic flow, and rainfall will all affect the degree of road aging, it is necessary to obtain a group of environmental change coefficients, among which the temperature change coefficient refers to a value that measures the degree of influence of temperature on road aging. The higher the degree of influence of temperature on road aging, the greater the temperature change coefficient. The traffic flow change coefficient refers to a value that measures the degree of influence of traffic flow on road aging. The higher the degree of influence of traffic flow on road aging, the greater the traffic flow change coefficient. The rainfall change coefficient refers to a value that measures the degree of influence of rainfall on road aging. The higher the degree of influence of rainfall on road aging, the greater the rainfall change coefficient.

[0040] Specifically, based on the preset maintenance cycle, the environmental prediction of the road to be maintained is performed to obtain an environmental change coefficient group, including: Confirming the current cycle, obtaining the current environmental parameter group of the current cycle, wherein the current environmental parameter group includes: the temperature of the current cycle, the traffic volume of the current cycle, and the rainfall of the current cycle; Predicting environmental parameters during the maintenance period to obtain a maintenance environmental parameter group, wherein the maintenance environmental parameter group includes: maintenance period temperature, maintenance period vehicle flow, and maintenance period rainfall; Based on the current environmental parameter group and the maintenance environmental parameter group, the temperature variation coefficient, the vehicle flow variation coefficient and the rainfall variation coefficient are calculated, wherein the temperature variation coefficient, the vehicle flow variation coefficient and the rainfall coefficient are respectively the ratio of the maintenance period temperature to the current period temperature, the ratio of the maintenance period vehicle flow to the current period vehicle flow, and the ratio of the maintenance period rainfall to the current period rainfall; The temperature variation coefficient, the vehicle flow variation coefficient and the rainfall variation coefficient are summarized to obtain an environment variation coefficient group.

[0041] It is understandable that the current cycle refers to the cycle in which the road to be maintained is currently located, and the current cycle is set manually and consists of multiple dates. The current cycle temperature, the current cycle traffic volume and the current cycle rainfall refer to the average temperature, the average traffic volume and the average rainfall on all dates of the current cycle respectively. The maintenance cycle temperature, the maintenance cycle traffic volume and the maintenance cycle rainfall refer to the average temperature, the average traffic volume and the average rainfall on all dates of the maintenance cycle respectively, wherein the temperature and rainfall within the maintenance cycle can be obtained through weather forecasts, and the traffic volume within the maintenance cycle can be manually predicted by the traffic volume in the same period of the previous year.

[0042] S4. Predict road damage on the road to be maintained based on the road aging value and the environmental change coefficient group to obtain a road damage rate, and determine whether the road damage rate is greater than a preset standard damage rate.

[0043] It can be understood that the road damage rate refers to the probability of road surface damage occurring on the road to be maintained within the maintenance cycle, and the standard damage rate refers to an artificially set constant.

[0044] Specifically, the road damage prediction for the road to be maintained is performed based on the road aging value and the environmental change coefficient group to obtain the road damage rate, including: Performing pavement parameter detection on the road to be maintained to obtain a pavement parameter group, wherein the pavement parameter group includes: pavement thickness, pavement porosity and pavement anti-skid value; Setting the daily pavement loss thickness of the road to be maintained; According to the daily pavement loss thickness, pavement parameter group, environmental change coefficient group and road aging value, the road damage rate is calculated using the following formula: ; in, represents the road damage rate, represents a natural constant, Indicates the preset thickness coefficient, Indicates the road surface thickness, Indicates the thickness of road surface loss per day, Indicates the number of days of the maintenance cycle. Indicates the road skid resistance value. represents the pavement porosity, Indicates the preset aging factor, Indicates the first An environmental variation coefficient.

[0045] It is understandable that the pavement thickness refers to the thickness of the road to be maintained. The pavement porosity refers to the porosity of the surface of the road to be maintained, wherein the porosity reflects the density of the surface of the road to be maintained. The higher the porosity, the fewer tiny pores on the surface to be maintained. These tiny pores are easy to absorb moisture and pollutants, thereby accelerating the aging and disease formation of the road. The high elastic potting glue can effectively fill these tiny pores and reduce the porosity, thereby improving the waterproof performance and anti-aging performance of the road. The pavement porosity can be detected by a porosity meter. The pavement anti-skid value refers to the value that measures the anti-skid performance of the road to be maintained. The stronger the anti-skid performance of the road to be maintained, the higher the pavement anti-skid value. A pendulum friction coefficient meter can be used to measure the pavement anti-skid value. The single-day pavement loss thickness refers to the daily loss value of the pavement thickness of the road to be maintained. The single-day pavement loss thickness can be obtained by long-term monitoring of the road thickness of the road to be maintained and then fitting the data. The thickness coefficient refers to the calculation weight of the thickness change when calculating the road damage rate, and the aging coefficient refers to the calculation weight of the road aging value when calculating the road damage rate. The thickness coefficient and the aging coefficient are set manually. Optionally, the thickness coefficient and the aging coefficient are 2.3 and 0.05 respectively. Indicates the first The specific environmental variation coefficient is: Indicates the temperature variation coefficient, represents the coefficient of traffic flow variation, represents the coefficient of variation of rainfall.

[0046] It needs to be explained that the calculation formula for the above road damage rate is explained as follows: the road thickness decreases over time, resulting in a decrease in the road bearing capacity. The nonlinear acceleration effect of thickness loss on road damage is reflected by the exponential function. The increase in porosity will aggravate water penetration and material degradation. Therefore, the pavement porosity is a promoting relationship in the calculation process of the road damage rate, and the increase in the anti-skid value will enhance the shear resistance of the road to be maintained. Therefore, the pavement anti-skid value is an inhibitory relationship in the calculation process of the road damage rate. The road aging value represents the material performance degradation ability, and is multiplied by the environmental change coefficient in the environmental change coefficient group to reflect the synergistic amplification effect of environmental mutation and traffic pressure on damage, and the exponential function highlights the irreversibility of time accumulation.

[0047] Importantly, the road surface parameter detection is performed on the road to be maintained to obtain a road surface parameter group, including: A sampling point group is set in the road to be maintained, and sampling points are sequentially extracted from the sampling point group; Performing ultrasonic testing on the sampling point to obtain the thickness of the sampling point, using a pre-acquired pendulum friction coefficient measuring instrument to measure the anti-slip value of the sampling point to obtain the anti-slip value of the sampling point, and using a pre-acquired porosity measuring instrument to measure the porosity of the sampling point to obtain the porosity of the sampling point; The thickness of the sampling points, the anti-slip value of the sampling points and the porosity of the sampling points are respectively summarized to obtain a sampling point thickness group, a sampling point anti-slip value group and a sampling point porosity group; The mean values ​​of the sampling point thickness group, sampling point anti-skid value group and sampling point porosity group were calculated respectively to obtain the pavement thickness, pavement anti-skid value and pavement porosity.

[0048] S5. If it is confirmed that the road damage rate is greater than the standard damage rate, the road to be maintained is recorded as a candidate maintenance road, and the pre-acquired high-elastic potting glue is modified to obtain an optimized potting glue.

[0049] It can be understood that the high-elastic potting glue is a commercially available polyurethane-based high-elastic potting glue, and its main components are: terminal hydroxyl polyurethane prepolymer (elastic matrix), plasticizer (phthalate), filler (calcium carbonate) and curing agent (isocyanate). When the polyurethane-based high-elastic potting glue is directly used for road covering, it has the problems of insufficient wear resistance (easy to wear under dynamic load), weak resistance to ultraviolet aging, low adhesion to the road surface, and inability to form a uniform thin layer. Therefore, it needs to be modified, and the modification method is to modify it using an optimized material group.

[0050] In detail, the method of modifying the pre-acquired high-elastic potting glue to obtain the optimized potting glue includes: An optimized material group was identified, wherein the optimized material group includes: nano-silicon dioxide, silicon carbide, cerium oxide, titanium dioxide, silane coupling agent KH-560, graphene, benzotriazole UV-326, HDI trimer and polyether modified silicone oil; The optimized material group is added to the pre-obtained high-elastic potting glue to obtain the optimized potting glue, wherein the high-elastic potting glue is a polyurethane-based high-elastic potting glue.

[0051] Furthermore, the detailed steps of adding the optimized material group to the pre-obtained high elastic potting glue are as follows: first, preparing the modified composite filler: adding nano-SiO 2 (Nano-silicon dioxide), SiC (silicon carbide), CeO 2 (Cerium Oxide) and TiO 2(titanium dioxide) are mixed in a preset ratio to obtain a first mixture, silane coupling agent KH-560 is added to the first mixture, and the mass of the added silane coupling agent KH-560 is 1% of the first mixture to obtain a second mixture, and the second mixture is ultrasonically dispersed at 60 degrees Celsius for 30 minutes to obtain a modified composite filler, and the HDI trimer is wrapped in a polyurethane shell material by an interfacial polymerization method, and the shell-core ratio is controlled at 1:3 to obtain microcapsules, and the particle size of the microcapsules is controlled at 50μm-100μm. Secondly, prepare the modified main agent: heat the polyurethane prepolymer to 50 degrees Celsius, and add plasticizer and polyether modified silicone oil to the heated terminal hydroxyl polyurethane prepolymer to obtain the first main agent, and stir the first main agent at a speed of 500rpm for 10 minutes to obtain the second main agent, then add modified composite filler and graphene to the second main agent, and high-speed shear dispersion at 1500rpm for 1 hour under nitrogen protection to obtain the third main agent, add benzotriazole UV-326 to the third main agent, and stir at 200rpm to obtain the modified main agent. Further, prepare a modified curing agent: add 0.5% nano cerium oxide to the curing agent to obtain a modified curing agent. Finally, the modified main agent and the modified curing agent are mixed in a mass ratio of 10:1 to obtain an optimized potting glue.

[0052] Need to explain, nano-SiO 2 As a hard filler, the particles are evenly dispersed in the polyurethane matrix to improve the surface hardness of the potting compound, thereby improving the wear resistance of the potting compound. SiC particles disperse the surface stress of the potting compound through the micro-convex structure, thereby reducing the surface plastic deformation. Since the preventive covering needs to withstand high-frequency vehicle rolling, SiC and SiO 2 The formation of a "soft and hard synergy" structure can reduce the amount of road wear. As open-air roads are exposed to ultraviolet rays for a long time, CeO 2 The redox ions provided can efficiently capture UV-induced free radicals, thereby delaying the photo-oxidative aging of roads. 2 It is impossible to completely block ultraviolet rays, so benzotriazole UV-326 is added, which reacts with CeO 2 The synergistic effect can further slow down the UV aging rate of roads. Nano titanium dioxide can produce reactive oxygen species (ROS) under ultraviolet excitation, thereby decomposing oil and organic matter adsorbed on the road surface, thereby delaying the aging of the road. The role of adding silane coupling agent KH-560 is to enhance the bonding strength between the potting glue and the road surface, and the addition of graphene can enhance the potting glue to have better elongation. Since the traditional potting glue has high viscosity and it is difficult to form a uniform thin layer, BYK-333 is added to reduce its viscosity, so that the optimized potting glue is easier to cover the road surface.

[0053] S6. Based on the road damage rate and the standard damage rate, the coverage thickness and coverage benefit value of the candidate maintenance roads are calculated, and the candidate maintenance roads, coverage thickness and coverage benefit values ​​are summarized respectively to obtain a candidate maintenance road set, a coverage thickness set and a coverage benefit value set.

[0054] It should be explained that the covering thickness refers to the covering thickness when the candidate maintenance road needs to be covered with high-elastic potting glue, and the covering benefit value refers to the benefit of covering the candidate maintenance road with high-elastic potting glue. The larger the covering benefit value, the lower the input-output ratio of covering the candidate maintenance road, that is, the smaller the benefit. The covering benefit value can be used to determine the order of covering the candidate maintenance roads.

[0055] In detail, the calculation of the coverage thickness and coverage benefit value of the candidate maintenance road based on the road damage rate and the standard damage rate includes: The coverage thickness is calculated using the following formula: ; in, Indicates the coverage thickness, represents the natural logarithm, represents the standard damage rate, Indicates the initial design thickness; Measuring the road area of ​​the road to be maintained, and determining the road grade weight of the road to be maintained, wherein the road grade weight includes: a main road grade weight, a secondary road grade weight, and a branch road grade weight; According to the road area and road grade weight, the coverage benefit value is calculated using the following formula: ; in, represents the coverage benefit value, It means optimizing the density of the potting compound. Represents the road area, Represents the road grade weight.

[0056] It can be understood that the initial design thickness refers to the thickness set when designing the candidate maintenance road, the road area refers to the area of ​​the road to be maintained, and the road grade weight refers to an artificially set constant. Since the grades of different roads are different, the benefits it can bring are also different. For example: when the road to be maintained is a main road, since the main road needs to carry a larger traffic volume, the benefit of covering the main road with potting glue is higher than that of the main road and branch road. Optionally, the main road grade weight, secondary road grade weight and branch road grade weight are 1.0, 0.7 and 0.4 respectively.

[0057] The explanation of the calculation formula for calculating the coverage benefit value above is required: the numerator in the above formula includes the coverage area and the coverage thickness. The larger the coverage area and the coverage thickness, the more potting glue materials need to be consumed, which leads to higher costs. The denominator includes the road grade weight and the degree of damage rate exceeding the standard. The degree of damage rate exceeding the standard is expressed as: The larger the road grade weight is, the more important the candidate maintenance road is, that is, the higher the benefit of covering the candidate maintenance road with sealant. The higher the degree of damage rate exceeding the standard, the more the road damage rate exceeds the standard damage rate, that is, the more urgent the maintenance of the candidate maintenance road is. Therefore, the larger the coverage benefit value is, the lower the input-output ratio of maintaining the candidate maintenance road is.

[0058] S7. Prioritize the candidate maintenance road set according to the coverage benefit value set to obtain a priority maintenance road set, wherein a priority maintenance road with a smaller ranking number in the priority maintenance road set has a higher maintenance priority.

[0059] It can be understood that the priority maintenance road set refers to the sorted candidate maintenance roads. Since different candidate maintenance roads have different coverage benefit values, the coverage order of the roads to be maintained can be sorted according to the coverage benefit values. The sorting rule is: the roads to be maintained with lower coverage benefit values ​​have higher priority for coverage, that is, the priority maintenance roads with smaller ranking numbers in the priority maintenance road set have higher maintenance priorities.

[0060] S8. Cover the priority maintenance road set with potting glue according to the covering thickness set and the optimized potting glue to obtain a target road set, and complete road maintenance based on the high-elastic potting glue based on the target road set.

[0061] It should be explained that covering the priority maintenance road set with sealant glue means: the priority maintenance roads with smaller arrangement orders in the priority maintenance road set are covered with higher priority, and when the priority maintenance roads are covered with optimized sealant glue, the covering thickness should be equal to the covering thickness corresponding to the priority maintenance roads.

[0062] In order to solve the problems described in the background technology, the present invention first uses satellite imagery to obtain road spectral images, and then performs road aging assessment based on the images, so as to comprehensively and objectively understand the current aging status of the road to be maintained. Compared with the traditional on-site manual inspection method, satellite imagery is not restricted by factors such as terrain and traffic, and can quickly obtain a large amount of road information. The road aging value obtained by spectral image analysis enables maintenance work to take corresponding measures for roads with different degrees of aging, thereby improving the efficiency and effectiveness of maintenance. Then, based on the maintenance cycle, the road environment is predicted to obtain an environmental change coefficient group. This process helps to understand in advance the environmental changes that the road may face in the future. By obtaining these environmental change coefficients, the future damage trend of the road can be more accurately predicted, thereby enhancing the foresight and adaptability of road maintenance. According to the road aging value and the environmental change coefficient group, the road damage prediction is performed to obtain the road damage rate, and it is judged whether it is greater than the standard damage rate. This step realizes the quantitative evaluation of the future damage degree of the road. By comparing with the standard damage rate, It is possible to clearly identify which roads need maintenance. This method avoids the subjectivity and uncertainty of judgment based on experience alone, first protects the roads that are really in urgent need of maintenance, and improves the overall quality of road maintenance and resource utilization efficiency. When it is confirmed that the road damage rate is greater than the standard damage rate, the high-elastic potting glue is modified to obtain an optimized potting glue. This step modifies the traditional potting glue so that the obtained optimized potting glue has better adaptability. Then, based on the road damage rate and the standard damage rate, the coverage thickness and coverage benefit value of the candidate maintenance road are calculated. By calculating the coverage thickness, it can be ensured that an appropriate amount of potting glue is used during the maintenance process, and the calculation of the coverage benefit value quantifies the value of the maintenance work, so that maintenance personnel can clearly understand the input-output ratio of each section of road maintenance, thereby achieving optimal allocation of resources and maximization of maintenance benefits. Then, the candidate maintenance road set is prioritized to obtain a priority maintenance road set. This sorting process enables maintenance work to prioritize those roads with higher coverage benefit values, thereby ensuring that limited maintenance resources can be first invested in the sections that can produce the most significant effects. Finally, the optimized potting glue is used to cover the priority maintenance road set with potting glue. In this step, the potting glue that is traditionally only used to fill cracks is innovatively used in preventive maintenance of roads, so that the roads can be effectively protected before they are seriously damaged, thereby increasing the service life of the roads. Therefore, the present invention can optimize the maintenance efficiency during the road maintenance process and increase the service life of the roads.
