[0168] A rapid repair construction method for potholes in asphalt pavement, one of the first embodiments of the present invention, comprises the following steps: During rapid repair construction of potholes in asphalt pavement, the raw material roll of the bottom layer fabric 30 is installed on the cylinder 71, and the nozzle is installed on the cross-sectional port of one of the ports of the discharge pipe II 63. The third mixer 4, the second mixer 8, and the first mixer 9 are in working condition, while valve I 43, valve III 83, and valve IV 97 are in a closed state. The temperature of the shells of the third mixer 4 and the second mixer 8 is maintained at 58-62°C. The raw material of the interface repair and strengthening composition is placed into the mixer I 41 using a crane 91. The raw material for the interface repair and strengthening layer 10 is obtained in the mixer I 41. The interface repair support... Bisphenol A liquid epoxy resin and reactive diluent from the support composition are placed in stirrer section II 81 to prepare a homogeneous solution. Basalt particles, mineral powder, reactive toughening agent, and curing agent are placed in stirrer section III 99. After being mixed evenly in stirrer section III 99, valve section III 83 is opened, and the homogeneous solution in stirrer section II 81 is injected into stirrer section III 99. The raw material for the interface repair support 20 is prepared in stirrer section III 99. The cylinder section 71 is rotated on the central shaft section 72, and the raw material of the bottom layer fabric 30 is placed into the storage tank 5. Valve section I 43 is opened, and the raw material of the interface repair reinforcement layer 10 in stirrer section I 41 is injected into the storage tank 5. The bottom layer fabric 30 is prepared in the storage tank 5.

[0169] The system reaches the rapid repair site for potholes in asphalt pavement via chassis 17. The transverse telescopic cylinder 32 moves the through beam 16 within the elongated opening of the movable frame 31. The longitudinal telescopic cylinder 35 moves the elongated opening of the movable frame 31 along the through beam 16, placing the drilling machine 33 at the pothole location and putting it into operation. The feed telescopic cylinder 34 moves the housing of the drilling machine 33 downwards on the vertical section of the vertical frame 36, allowing the helical blades of the drilling machine 33 to drill holes in the pothole. After drilling is complete, the drilling machine 33 is deactivated, the feed telescopic cylinder 34 is retracted, and the excavation assembly 2 is activated. The excavation assembly 2 then excavates and cleans the pothole, resulting in the asphalt pavement pothole.

[0170] Remove the bottom layer fabric 30 from the storage tank 5 and lay it flat in the asphalt pavement pothole, ensuring the flange width of the bottom layer fabric 30 on the asphalt pavement at the edge of the pothole is 10-15 cm. Open valve section IV 97 and feed the raw material of the boundary base repair support 20 from mixer section III 99 onto the bottom layer fabric 30. Spread the raw material of the boundary base repair support 20 in the asphalt pavement pothole into a flat surface. When the raw material of the boundary base repair support 20 in the asphalt pavement pothole is full, close valve section IV 97. The boundary base repair support 20 is thus formed in the asphalt pavement pothole. Ensure the flange of the bottom layer fabric 30 on the asphalt pavement at the edge of the pothole is vertical. Open valve section II 64 and operate pump section 61. In operation, the material of the interface repair and strengthening layer 10 located in the storage tank 5 is sprayed onto the asphalt pavement at the edge of the pothole through the nozzle. Then, the flange of the bottom layer cloth 30 on the asphalt pavement at the edge of the pothole is laid horizontally. The material of the interface repair and strengthening layer 10 located in the storage tank 5 is sprayed onto the flange of the bottom layer cloth 30 on the asphalt pavement at the edge of the pothole and the boundary base repair support 20 through the nozzle. The interface repair and strengthening layer 10 is formed on the flange of the bottom layer cloth 30 on the asphalt pavement at the edge of the pothole and the boundary base repair support 20. After the rapid repair construction of the asphalt pavement pothole is completed, the pump unit 61 is put into a non-working state, the valve unit II 64 is put into a closed state, and the third mixer 4, the second mixer 8 and the first mixer 9 are put into a non-working state.

Figure 4 As a second embodiment of the first embodiment of the present invention, this embodiment is described in detail with reference to the accompanying drawings. It also includes a standing block 50 and a through rod 40, and the standing block 50 is configured to be connected to the through rod 40 in a sleeve manner. The standing block 50 and the through rod 40 are respectively configured to be embeddedly connected to the boundary base repair support 20. The upper and lower ends of the standing block 50 are configured to be connected to the bottom layer fabric 30.

[0172] In this embodiment, the upright block 50 is configured as a cement mortar casting seat with a through hole, and the through hole of the upright block 50 is configured to be connected to the through rod 40. The lower end face of the upright block 50 is configured to be in contact with the bottom layer fabric 30, and the upper end face and the upper side of the upright block 50 are configured to be in contact with the bottom layer fabric 30. The lower side of the upright block 50 is configured to be in contact with the boundary repair support 20.

[0173] The upright block 50 forms a support connection point for the boundary repair support 20, the bottom layer fabric 30, and the through rod 40. The upright block 50 realizes the connection with the boundary repair support 20, the connection with the bottom layer fabric 30, and the connection with the through rod 40. Its technical purpose is to be used as a component for separating potholes in asphalt pavement.

[0174] In this embodiment, the through rod 40 is configured as a force transmission rod and is embedded in the boundary base repair support 20. The through rod 40 is also configured to be connected through the upright block 50.

[0175] The through rod 40 forms a support connection point for the boundary base repair support 20 and the upright block 50. The through rod 40 realizes the connection with the boundary base repair support 20 and the connection with the upright block 50. Its technical purpose is to serve as a component for integral connection of adjacent upright blocks 50.

[0176] A rapid repair construction method for potholes in asphalt pavement, the second embodiment of the present invention, comprises the following steps: When rapidly repairing potholes in asphalt pavement, after the bottom layer cloth 30 is laid flat in the pothole, a vertical block 50 is placed on the bottom layer cloth 30 in the pothole, a through rod 40 is installed in the through hole of the vertical block 50, another bottom layer cloth 30 is placed on the upper end face and the upper side of the vertical block 50, a boundary repair support 20 is formed in the pothole, and then an interface repair reinforcement layer 10 is formed on the flange of the bottom layer cloth 30 on the asphalt pavement at the edge of the pothole, the boundary repair support 20 and the bottom layer cloth 30 on the vertical block 50.

[0177] In verifying this invention, the inventors abandoned the existing technical features that use asphalt and cement mortar as repair materials, resulting in a weak bonding force with the asphalt pavement fracture surface. Instead, they first proposed a technical feature that allows the repaired material to achieve a dense state with a rapid curing rate. This resulted in the first unexpected technical effect: improved adhesive performance, excellent density of the repaired material, and increased load-bearing capacity. The second unexpected technical effect: achieved primary bonding force from the upper and lower layers and secondary bonding force from the side layers themselves, improving the bonding force with the asphalt pavement fracture surface and ensuring the stability of the repaired material in potholes. The third unexpected technical effect: suitable for filling and repairing potholes of different sizes. The fourth unexpected technical effect: enabled the installation of a mobile vehicle repair construction device, expanding the repair operation range. The fifth unexpected technical effect: enabled the pre-preparation of the raw materials for the interface repair reinforcement layer 10, the interface base repair support 20, and the bottom layer fabric 30, improving repair construction efficiency.

[0178] In a second embodiment of the present invention, the technical features of enabling the repair material to be in a dense state with a rapid curing rate are integrated into the interfacial repair support composition and the interface repair reinforcement composition.

[0179] In this embodiment, the enhanced adhesive compound is integrated into the boundary repair support composition and the interface repair strengthening composition according to the technical characteristics of the component.

[0180] The second embodiment of the present invention is based on the first embodiment.

[0181] This invention has the following characteristics:

[0182] 1. By designing the base repair support composition and the interface repair reinforcement composition, the reinforced adhesive compound is used as a component, and the repaired material is in a dense state with a rapid curing rate. This solves the technical problem that the bonding strength with the fracture surface of the asphalt pavement is weak when using asphalt and cement mortar as repair materials, thus improving the quality of rapid repair of potholes in asphalt pavement.

[0183] 2. Due to the design of the interface repair reinforcement layer 10, the interface base repair support 20 and the bottom layer cloth 30, the filling and repair of potholes in asphalt pavement were achieved.

[0184] 3. Due to the design of the vertical block 50 and the through rod 40, it is possible to fill and repair large-area potholes in asphalt pavement.

[0185] 4. By designing a motorized chassis 1, an excavation assembly 2, a drilling assembly 3, a third mixer 4, a storage tank 5, a spraying assembly 6, an unwinding assembly 7, a second mixer 8, a first mixer 9, and a crane 91, the vehicle-mounted components were able to fill and repair potholes in asphalt pavement.

[0186] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0187] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0188] Other technical features that are the same as or similar to those of the interfacial repair support composition and the interface repair reinforcement composition that enable the repaired material to be in a dense state with a rapid curing rate are also embodiments of the present invention. Furthermore, the technical features of the embodiments described above can be combined in any way. In order to meet the requirements of the Patent Law, the Patent Implementation Regulations and the Examination Guidelines, embodiments of all possible combinations of the technical features in the above embodiments will not be described.
