[0002] Three-dimensional scanning, also known as 3D scanning, refers to a high-tech technology that integrates optical, mechanical, electrical and computer technologies. It is mainly used to scan the spatial shape, structure and color of an object to obtain the spatial coordinates of the object's surface. With the acceleration of travel speed requirements and the continuous enhancement of driving experience, people have higher and higher requirements for road quality, which puts higher requirements on road paving and acceptance. At present, the road parameter testing method mainly relies on manual walking observation, which has the problems of poor safety of operators and low detection efficiency. Moreover, if the detection is wrong during paving, there will be the disadvantage of rework. In recent years, with the rapid development of three-dimensional detection technology, the road parameter testing method based on 3D scanning has gradually attracted attention.

[0071] Among them, before paving the road, the road will first be standardized according to the road use requirements and the surrounding environment. The paving of the road involves multiple paving construction layer process links, including the cushion layer, base layer, and surface layer. The requirements of each layer are different.

Then obtain the scanning real-time parameter data, the pavement standard physical parameter set and the pavement real-time physical parameter data; according to the obtained information, combined with the real-time paving construction layer data query and match to obtain the process standard parameter data and the process standard physical parameter data, and then calculate to obtain the first pavement parameter evaluation data and the second pavement parameter evaluation data, and obtain the pavement parameter comprehensive evaluation data after processing, and obtain the pavement parameter test status data after the comprehensive evaluation data of the pavement is compared with the threshold.

According to an embodiment of the present invention, obtaining a standard parameter set for pavement paving, scanning real-time parameter data, a standard physical parameter set of a pavement, and real-time physical parameter data of a pavement specifically includes:

[0073] S21, obtaining a standard parameter set for road paving, including a cushion layer standard parameter set, a base layer standard data set, and a surface layer standard data set, wherein each layer standard data set includes standard flatness data, standard width data, standard layer thickness data, and standard slope data;

[0077] Among them, obtaining the standard parameter set refers to obtaining the data of each construction layer of road paving and the standard requirement data of each construction layer, which specifically includes the cushion layer standard parameter set, the base layer standard data set and the surface layer standard data set. Due to different user requirements for road function and different project budgets, the requirements for each construction layer of the road are also different, and the standard flatness data, standard width data, standard layer thickness data and standard slope data of each construction layer are also different; standard flatness data refers to data reflecting the flatness of each construction layer when the road is paved; standard width data refers to the width data of each construction layer; standard slope data refers to the data required to ensure smooth drainage and prevent It can stop water accumulation from damaging the roadbed while meeting the longitudinal and transverse slope data required for road use; the real-time parameter data scanned refers to the real-time parameter data obtained by scanning the current construction layer in real time according to the test requirements; the standard physical parameter set of the road surface refers to the data of each construction layer of the road surface and the standard physical parameter data of each construction layer. The standard physical parameter data includes standard compaction data and standard material quality number; the real-time physical parameter data of the road surface refers to the physical parameter data obtained during the construction of the real-time construction layer; the compaction data reflects the density of the roadbed fill, which directly affects the strength and stability of the roadbed; the material quality data reflects the quality of the material to a certain extent.

[0078] According to an embodiment of the present invention, the real-time paving construction layer data is acquired, and the process standard parameter data is obtained by matching the real-time paving construction layer data with the standard parameter set, specifically including:

[0079] Using the real-time paving construction layer data as a keyword to perform query and match in the standard parameter set, and obtaining process standard parameter data;

[0080] The process standard parameter data includes process standard flatness data, process standard width data, process standard layer thickness data and process standard slope data.

[0081] Among them, to realize the test of paving construction layer parameters, we must first determine the current construction layer, obtain the real-time paving construction layer data, and then query and match the standard parameter set according to the real-time paving construction layer data to obtain the matching standard data, and then record it as the process standard parameter data, that is, the standard design parameters of the current construction layer process. The process standard flatness data refers to the standard flatness data of the current construction layer process; the process standard width data refers to the standard width data of the current construction layer process; the process standard layer thickness data refers to the standard layer thickness data of the current construction layer process; the process standard slope data refers to the standard slope data of the current construction layer process.

[0082] According to an embodiment of the present invention, the first pavement parameter evaluation data is calculated based on the process standard parameter data and the scanned real-time parameter data, specifically including:

[0084] The calculation formula of the first evaluation data of the road surface parameter in the first road surface parameter detection model is:

[0085]

[0086] Among them, C dy is the first evaluation data of road surface parameters, G pz is the process standard flatness data, G kd is the process standard width data, G ch is the standard layer thickness data of the process, G pd is the standard slope data of the process, S pz is the real-time flatness data, S kd is the real-time width data, S ch is the real-time layer thickness data, S pd is the real-time slope data, and α, β1, β2, β3, β4, χ1, χ2, χ3, and χ4 are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset pavement parameter test platform based on 3D scanning).

[0087] Among them, the first evaluation data of pavement parameters can be obtained by calculating the process standard parameter data and the scanned real-time parameter data. The first evaluation data of pavement parameters reflects to a certain extent the deviation of the pavement parameters from the design standards. By calculating the first evaluation data of pavement parameters, the first influencing factor of the pavement parameters can be obtained; the preset pavement parameter first detection model is a calculation model obtained by obtaining a large amount of process standard flatness data, process standard width data, process standard layer thickness data, process standard slope data, real-time flatness data, real-time width data, real-time layer thickness data and real-time slope data, and then performing model training, which can calculate the first evaluation data of pavement parameters.

[0088] According to an embodiment of the present invention, obtaining process standard physical parameter data by matching the real-time paving layer data with the pavement standard physical parameter set specifically includes:

[0089] Using the real-time paving construction layer data as a keyword to perform query and match in the pavement standard physical parameter set, to obtain process standard physical parameter data;

[0090] The process standard physical parameter data includes process compaction standard data and process material quality standard data.

[0091] Among them, in order to realize the test of paving construction layer parameters, another influencing factor is physical parameter data. After determining the current paving construction layer, the process standard physical parameter data is obtained through query matching. The process standard physical parameter data refers to the physical parameter data corresponding to the current paving construction layer process.

[0092] According to an embodiment of the present invention, the process standard physical parameter data and the real-time physical parameter data of the road surface are processed by a preset road surface parameter second detection model to obtain the second road surface parameter evaluation data, specifically including:

[0093] Inputting the process compaction standard data, process material quality standard data, real-time compaction data and real-time material quality data into a preset pavement parameter second detection model for processing to obtain pavement parameter second evaluation data;

[0094] The calculation formula of the second evaluation data of the road surface parameter in the second detection model of the road surface parameter is:

[0095]

[0096] Among them, C de is the second evaluation data of road surface parameters, G ys is the standard data of process compaction degree, G cz is the process material quality standard data, S ys is the real-time compaction data, S cz is the real-time material quality data, and δ1, δ2, and ε are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset pavement parameter test platform based on 3D scanning).

[0097] Among them, the second evaluation data of the pavement parameters can be obtained by calculating the standard physical parameter data of the process and the real-time physical parameter data of the pavement. The second evaluation data of the pavement parameters reflect to a certain extent the deviation of the pavement parameters from the design standards. By calculating the second evaluation data of the pavement parameters, the second influencing factor of the pavement parameters can be obtained; the preset pavement parameter second detection model is a calculation model obtained by obtaining a large amount of process compaction standard data, process material quality standard data, real-time compaction data and real-time material quality data, and then performing model training, which can calculate the second evaluation data of the pavement parameters.

[0098] According to an embodiment of the present invention, the calculating and obtaining the pavement parameter comprehensive evaluation data according to the pavement parameter first evaluation data and the pavement parameter second evaluation data specifically includes:

[0099] Inputting the first pavement parameter evaluation data and the second pavement parameter evaluation data into a preset pavement parameter comprehensive evaluation data model for processing to obtain pavement parameter comprehensive evaluation data;

[0100] The calculation formula of the pavement parameter comprehensive evaluation data in the pavement parameter comprehensive evaluation data model is:

[0101] C s =γC dy *C de ;

[0102] Among them, C s is the comprehensive evaluation data of pavement parameters, C dy is the first evaluation data of pavement parameters, C de is the second evaluation data of the pavement parameters, and γ is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset pavement parameter test platform based on 3D scanning).

[0103] Among them, the first evaluation data of pavement parameters and the second evaluation data of pavement parameters are both influencing factors that affect the pavement parameter test. Therefore, the two can be calculated through the preset pavement parameter comprehensive evaluation data model to obtain the pavement parameter comprehensive evaluation data. The pavement parameter comprehensive evaluation data reflects the pavement parameter data situation to a certain extent, and then can reflect the pavement quality data. The pavement parameter comprehensive evaluation data model is a calculation model that can calculate the pavement parameter comprehensive evaluation data after training with a large amount of historical data.

[0104] Please refer to Figure 3 , Figure 3 The present invention provides a flow chart of obtaining pavement parameter test status data of a pavement parameter test method based on 3D scanning according to an embodiment of the present invention. According to an embodiment of the present invention, the pavement parameter comprehensive evaluation data is compared with a preset pavement parameter test threshold to obtain pavement parameter test status data, specifically including:

[0105] S31, comparing the pavement parameter comprehensive evaluation data with a preset pavement parameter test threshold to obtain pavement parameter test status data;

[0106] S32, extracting a first threshold and a second threshold according to the road surface parameter test threshold, and the first threshold is greater than the second threshold;

[0107] S33, comparing the comprehensive evaluation data of road surface parameters with the first threshold and the second threshold;

[0108] S34, if the pavement parameter comprehensive evaluation data is greater than the first threshold value, the pavement parameter test status data is pavement quality qualified data;

[0109] S35, if the pavement parameter comprehensive evaluation data is greater than the second threshold value and less than or equal to the first threshold value, the pavement parameter test state data is pavement quality transition use data;

[0110] S36. If the pavement parameter comprehensive evaluation data is less than or equal to the second threshold value, the pavement parameter test status data is unqualified pavement quality data.

[0111] Among them, the comprehensive evaluation data of pavement parameters directly affects the parameters and quality of pavement paving. Therefore, by comparing the comprehensive evaluation data of pavement parameters with the preset pavement parameter test threshold, the pavement parameter test status data can be obtained. The pavement parameter test status data includes pavement quality qualified data, pavement quality transition use data or pavement quality unqualified data. The pavement quality qualified data means that the pavement parameters are normal and the pavement quality is qualified; the pavement quality transition use data means that the pavement parameters or pavement quality are within the allowable floating range, but the parameters or quality need to be improved. In this state, although the pavement parameters and quality meet the standards, there is a risk of falling to unqualified; unqualified pavement quality data means that the pavement parameters are unreasonable, the pavement quality does not meet the standards, and the pavement paving process needs to be adjusted; in this embodiment, the pavement parameter test threshold is set to: [0, 0.75), unqualified pavement quality data; [0.75, 0.85), pavement quality transition use data; [0.85, 1], pavement quality qualified data; when the calculated pavement parameter comprehensive evaluation data is 0.89, the pavement parameter test status data is the pavement quality qualified data.

[0112] It is worth mentioning that it also includes:

[0113] Obtain a preset number of pavement parameter test status data within a preset length of data;

[0114] Classify and count the pavement parameter test status data to obtain classified frequency data of the pavement parameter test status, including the number of times the pavement quality is qualified, the number of times the pavement quality is transitionally used, or the number of times the pavement quality is unqualified;

[0115] The pavement paving process qualified state index is calculated based on the length data, the number of qualified pavement quality times, the number of pavement quality transition use times and the number of unqualified pavement quality times;

[0116] The pavement paving process qualified status index is compared with a preset pavement paving process threshold to obtain the pavement paving process qualified status, including the pavement paving process qualified or the pavement paving process unqualified.

[0117] Among them, the pavement paving process is all mechanized and automated operations. The process equipment may have unreasonable process parameter settings or equipment failures during the paving process. Single or a few unqualified quality is not representative, and it cannot be judged that it is a process parameter setting problem or equipment failure problem. Therefore, it is necessary to count the classification frequency data of the pavement parameter test status within the preset length data, and calculate the pavement paving process qualified status index based on the length data, the number of qualified pavement quality, the number of pavement quality transition use times and the number of unqualified pavement quality. The pavement paving process qualified status index refers to the data that can reflect the process parameters or equipment failure problems in the construction process to a certain extent. The calculation formula of the pavement paving process qualified status index is:

[0118]

[0119] Among them, C d , H g , G d , B h They are length data, number of times the road surface quality is qualified, number of times the road surface quality is used in transition, number of times the road surface quality is unqualified, and η and λ are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset road surface parameter test platform based on 3D scanning).

[0120] The present invention also discloses a road surface parameter testing system based on 3D scanning, comprising a memory and a processor, wherein the memory comprises a road surface parameter testing method program based on 3D scanning, and when the road surface parameter testing method program based on 3D scanning is executed by the processor, the following steps are implemented:

[0122] Acquire real-time paving construction layer data, and obtain process standard parameter data by matching the real-time paving construction layer data with the standard parameter set;

[0123] Calculate and obtain first road surface parameter evaluation data based on the process standard parameter data and the scanned real-time parameter data;

[0124] Obtaining process standard physical parameter data by matching the real-time paving layer data with the pavement standard physical parameter set;

[0125] The process standard physical parameter data and the real-time physical parameter data of the road surface are processed by a preset second road surface parameter detection model to obtain second road surface parameter evaluation data;

[0126] Calculate and obtain the pavement parameter comprehensive evaluation data according to the first pavement parameter evaluation data and the second pavement parameter evaluation data;

[0127] The pavement parameter comprehensive evaluation data is compared with a preset pavement parameter test threshold to obtain pavement parameter test status data.

[0128] Among them, before paving the road, the road will first be standardized according to the road use requirements and the surrounding environment. The paving of the road involves multiple paving construction layer process links, including the cushion layer, base layer, and surface layer. The requirements of each layer are different. Therefore, it is necessary to obtain a standard parameter set for pavement paving, including the standard requirements of each paving construction layer. In this embodiment, 3D scanning can be performed in real time according to the progress of pavement paving, that is, after paving, parameter testing is directly performed to determine that the quality is within the standard range. First, it can ensure the paving quality in time, and second, it can prevent the occurrence of rework events. Then obtain the scanning real-time parameter data, the pavement standard physical parameter set and the pavement real-time physical parameter data; according to the obtained information, combined with the real-time paving construction layer data query and match to obtain the process standard parameter data and the process standard physical parameter data, and then calculate to obtain the first pavement parameter evaluation data and the second pavement parameter evaluation data, and obtain the pavement parameter comprehensive evaluation data after processing, and obtain the pavement parameter test status data after the comprehensive evaluation data of the pavement is compared with the threshold.

[0129] According to an embodiment of the present invention, the acquisition of a standard parameter set for pavement paving, scanning real-time parameter data, a standard physical parameter set for pavement, and real-time physical parameter data for pavement specifically includes:

[0134] Among them, obtaining the standard parameter set refers to obtaining the data of each construction layer of road paving and the standard requirement data of each construction layer, which specifically includes the cushion layer standard parameter set, the base layer standard data set and the surface layer standard data set. Due to different user requirements for road function and different project budgets, the requirements for each construction layer of the road are also different, and the standard flatness data, standard width data, standard layer thickness data and standard slope data of each construction layer are also different; standard flatness data refers to data reflecting the flatness of each construction layer when the road is paved; standard width data refers to the width data of each construction layer; standard slope data refers to the data required to ensure smooth drainage and prevent It can stop water accumulation from damaging the roadbed while meeting the longitudinal and transverse slope data required for road use; the real-time parameter data scanned refers to the real-time parameter data obtained by scanning the current construction layer in real time according to the test requirements; the standard physical parameter set of the road surface refers to the data of each construction layer of the road surface and the standard physical parameter data of each construction layer. The standard physical parameter data includes standard compaction data and standard material quality number; the real-time physical parameter data of the road surface refers to the physical parameter data obtained during the construction of the real-time construction layer; the compaction data reflects the density of the roadbed fill, which directly affects the strength and stability of the roadbed; the material quality data reflects the quality of the material to a certain extent.

[0135] According to an embodiment of the present invention, the real-time paving construction layer data is acquired, and the process standard parameter data is obtained by matching the real-time paving construction layer data with the standard parameter set, specifically including:

[0136] Using the real-time paving construction layer data as a keyword to perform query and match in the standard parameter set, and obtaining process standard parameter data;

[0137] The process standard parameter data includes process standard flatness data, process standard width data, process standard layer thickness data and process standard slope data.

[0138] Among them, to realize the test of paving construction layer parameters, we must first determine the current construction layer, obtain the real-time paving construction layer data, and then query and match the standard parameter set according to the real-time paving construction layer data to obtain the matching standard data, and then record it as the process standard parameter data, that is, the standard design parameters of the current construction layer process. The process standard flatness data refers to the standard flatness data of the current construction layer process; the process standard width data refers to the standard width data of the current construction layer process; the process standard layer thickness data refers to the standard layer thickness data of the current construction layer process; the process standard slope data refers to the standard slope data of the current construction layer process.

[0139] According to an embodiment of the present invention, the first pavement parameter evaluation data is calculated based on the process standard parameter data and the scanned real-time parameter data, specifically including:

[0141] The calculation formula of the first evaluation data of the road surface parameter in the first road surface parameter detection model is:

[0142]

[0143] Among them, C dy is the first evaluation data of road surface parameters, G pz is the process standard flatness data, G kd is the process standard width data, G ch is the standard layer thickness data of the process, G pd is the standard slope data of the process, S pz is the real-time flatness data, S kd is the real-time width data, S ch is the real-time layer thickness data, S pd is the real-time slope data, and α, β1, β2, β3, β4, χ1, χ2, χ3, and χ4 are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset pavement parameter test platform based on 3D scanning).

[0144] Among them, the first evaluation data of pavement parameters can be obtained by calculating the process standard parameter data and the scanned real-time parameter data. The first evaluation data of pavement parameters reflects to a certain extent the deviation of the pavement parameters from the design standards. By calculating the first evaluation data of pavement parameters, the first influencing factor of the pavement parameters can be obtained; the preset pavement parameter first detection model is a calculation model obtained by obtaining a large amount of process standard flatness data, process standard width data, process standard layer thickness data, process standard slope data, real-time flatness data, real-time width data, real-time layer thickness data and real-time slope data, and then performing model training, which can calculate the first evaluation data of pavement parameters.

[0145] According to an embodiment of the present invention, obtaining process standard physical parameter data by matching the real-time paving layer data with the pavement standard physical parameter set specifically includes:

[0146] Using the real-time paving construction layer data as a keyword to perform query and match in the pavement standard physical parameter set, to obtain process standard physical parameter data;

[0147] The process standard physical parameter data includes process compaction standard data and process material quality standard data.

[0148] Among them, in order to realize the test of paving construction layer parameters, another influencing factor is physical parameter data. After determining the current paving construction layer, the process standard physical parameter data is obtained through query matching. The process standard physical parameter data refers to the physical parameter data corresponding to the current paving construction layer process.

[0149] According to an embodiment of the present invention, the process standard physical parameter data and the real-time physical parameter data of the road surface are processed by a preset road surface parameter second detection model to obtain the second road surface parameter evaluation data, specifically including:

[0150] Inputting the process compaction standard data, process material quality standard data, real-time compaction data and real-time material quality data into a preset pavement parameter second detection model for processing to obtain pavement parameter second evaluation data;

[0151] The calculation formula of the second evaluation data of the road surface parameter in the second detection model of the road surface parameter is:

[0152]

[0153] Among them, C de is the second evaluation data of road surface parameters, G ys is the standard data of process compaction degree, G cz is the process material quality standard data, S ys is the real-time compaction data, S cz is the real-time material quality data, and δ1, δ2, and ε are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset pavement parameter test platform based on 3D scanning).

[0154] Among them, the second evaluation data of the pavement parameters can be obtained by calculating the standard physical parameter data of the process and the real-time physical parameter data of the pavement. The second evaluation data of the pavement parameters reflect to a certain extent the deviation of the pavement parameters from the design standards. By calculating the second evaluation data of the pavement parameters, the second influencing factor of the pavement parameters can be obtained; the preset pavement parameter second detection model is a calculation model obtained by obtaining a large amount of process compaction standard data, process material quality standard data, real-time compaction data and real-time material quality data, and then performing model training, which can calculate the second evaluation data of the pavement parameters.

[0155] According to an embodiment of the present invention, the calculating and obtaining the pavement parameter comprehensive evaluation data according to the pavement parameter first evaluation data and the pavement parameter second evaluation data specifically includes:

[0156] Inputting the first pavement parameter evaluation data and the second pavement parameter evaluation data into a preset pavement parameter comprehensive evaluation data model for processing to obtain pavement parameter comprehensive evaluation data;

[0157] The calculation formula of the pavement parameter comprehensive evaluation data in the pavement parameter comprehensive evaluation data model is:

[0158] C s =γC dy *C de ;

[0159] Among them, C s is the comprehensive evaluation data of pavement parameters, C dy is the first evaluation data of pavement parameters, C de is the second evaluation data of the pavement parameters, and γ is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset pavement parameter test platform based on 3D scanning).

[0160] Among them, the first evaluation data of pavement parameters and the second evaluation data of pavement parameters are both influencing factors that affect the pavement parameter test. Therefore, the two can be calculated through the preset pavement parameter comprehensive evaluation data model to obtain the pavement parameter comprehensive evaluation data. The pavement parameter comprehensive evaluation data reflects the pavement parameter data situation to a certain extent, and then can reflect the pavement quality data. The pavement parameter comprehensive evaluation data model is a calculation model that can calculate the pavement parameter comprehensive evaluation data after training with a large amount of historical data.

[0161] According to an embodiment of the present invention, comparing the pavement parameter comprehensive evaluation data with a preset pavement parameter test threshold to obtain pavement parameter test status data specifically includes:

[0162] S31, comparing the pavement parameter comprehensive evaluation data with a preset pavement parameter test threshold to obtain pavement parameter test status data;

[0163] Extracting a first threshold and a second threshold according to the road surface parameter test threshold, wherein the first threshold is greater than the second threshold;

[0164] Comparing the comprehensive evaluation data of the road surface parameters with the first threshold and the second threshold;

[0165] If the pavement parameter comprehensive evaluation data is greater than the first threshold value, the pavement parameter test status data is pavement quality qualified data;

[0166] If the pavement parameter comprehensive evaluation data is greater than the second threshold value and less than or equal to the first threshold value, the pavement parameter test state data is pavement quality transition use data;

[0167] If the pavement parameter comprehensive evaluation data is less than or equal to the second threshold, the pavement parameter test status data is unqualified pavement quality data.

[0168] Among them, the comprehensive evaluation data of pavement parameters directly affects the parameters and quality of pavement paving. Therefore, by comparing the comprehensive evaluation data of pavement parameters with the preset pavement parameter test threshold, the pavement parameter test status data can be obtained. The pavement parameter test status data includes pavement quality qualified data, pavement quality transition use data or pavement quality unqualified data. The pavement quality qualified data means that the pavement parameters are normal and the pavement quality is qualified; the pavement quality transition use data means that the pavement parameters or pavement quality are within the allowable floating range, but the parameters or quality need to be improved. In this state, although the pavement parameters and quality meet the standards, there is a risk of falling to unqualified; unqualified pavement quality data means that the pavement parameters are unreasonable, the pavement quality does not meet the standards, and the pavement paving process needs to be adjusted; in this embodiment, the pavement parameter test threshold is set to: [0, 0.75), unqualified pavement quality data; [0.75, 0.85), pavement quality transition use data; [0.85, 1], pavement quality qualified data; when the calculated pavement parameter comprehensive evaluation data is 0.89, the pavement parameter test status data is the pavement quality qualified data.

[0169] It is worth mentioning that it also includes:

[0170] Obtain a preset number of pavement parameter test status data within a preset length of data;

[0171] Classify and count the pavement parameter test status data to obtain classified frequency data of the pavement parameter test status, including the number of times the pavement quality is qualified, the number of times the pavement quality is transitionally used, or the number of times the pavement quality is unqualified;

[0172] The pavement paving process qualified state index is calculated based on the length data, the number of qualified pavement quality times, the number of pavement quality transition use times and the number of unqualified pavement quality times;

[0173] The pavement paving process qualified status index is compared with a preset pavement paving process threshold to obtain the pavement paving process qualified status, including the pavement paving process qualified or the pavement paving process unqualified.

[0174] Among them, the pavement paving process is all mechanized and automated operations. The process equipment may have unreasonable process parameter settings or equipment failures during the paving process. Single or a few unqualified quality is not representative, and it cannot be judged that it is a process parameter setting problem or equipment failure problem. Therefore, it is necessary to count the classification frequency data of the pavement parameter test status within the preset length data, and calculate the pavement paving process qualified status index based on the length data, the number of qualified pavement quality, the number of pavement quality transition use times and the number of unqualified pavement quality. The pavement paving process qualified status index refers to the data that can reflect the process parameters or equipment failure problems in the construction process to a certain extent. The calculation formula of the pavement paving process qualified status index is:

[0175]

[0176] Among them, C d , H g , G d , B h They are length data, number of times the road surface quality is qualified, number of times the road surface quality is used in transition, number of times the road surface quality is unqualified, and η and λ are preset characteristic coefficients (the characteristic coefficients are obtained by querying the preset road surface parameter test platform based on 3D scanning).
