Fig. 1A to 1C are photographs showing the state of development of crack-type defects of asphalt pavement, wherein fig. 1A is a photograph showing that crack-type defects of asphalt pavement are expressed as single cracks, fig. 1B is a photograph showing that crack-type defects of asphalt pavement are expressed as block cracks, and fig. 1C is a photograph showing that crack-type defects of asphalt pavement are expressed as web cracks. As shown in fig. 1A to fig. 1C, the development stages of the asphalt pavement crack diseases include single crack, block crack, net crack and pit slot. The aim of pavement maintenance is to treat single cracks of a pavement in time and avoid the cracks from developing to form block cracks, net cracks and even pits. Once the road surface has net cracks or pits, the following steps are required for repairing: before repairing the local damage of the asphalt pavement, grooving and molding the broken part, dividing a rectangular contour line of a net crack or a pit groove according to a 'round hole square repair' principle, ensuring that each edge enters at least 10cm of an intact pavement (namely excavating loose and broken old materials of the pavement till a solid part), and then planing the excavated old materials; cleaning broken stones and waste residues in and around the pit groove, wherein sundries such as mud, rain, snow, ice blocks and the like cannot be stored in the pit groove, the pit groove should be trimmed orderly, and the solid firm surface is required to be obtained when the waste residues are removed; before paving the asphalt mixture in the pit slot, uniformly spraying a layer of adhesive layer oil on the wall surface and the bottom surface of the pit slot to infiltrate exposed stone materials on the inner surface of the pit slot, so that the bonding effect between the asphalt mixture and the original pavement material is improved; pouring the asphalt mixture into the pit until the filler is about 1-2 cm higher than the road surface, wherein the center of the pit is slightly higher than the road surface and is convex after the filling; after the pit is laid evenly, a proper compaction tool and a proper compaction method (such as a small vibration compactor, a small road roller and the like) are selected for compaction according to the size and the depth of the repair area, in the compaction process, if a part with few materials is found, material supplement is carried out immediately, and after the compaction is finished, the edge of the pit can be sealed by asphalt if necessary; the repaired pit groove has smooth surface, no wheel trace, good compaction of the periphery and corners of the pit groove, no loosening and other phenomena, and the traffic can be opened after the pit groove is repaired. In addition, for the pit with the damage depth of more than 5cm, 3-5 cm is needed to be used as one layer, and the pit is filled in layers and compacted layer by layer.
However, the following problems are present when the above repairing method is employed: the construction process is complex, has great influence on traffic, and is easy to produce waste materials and discharge harmful gases, thereby polluting the surrounding environment of roads. In addition, taking the example of repairing a 1-square-meter pit, it takes 1 hour to adopt the above modification method.

Referring to fig. 2, the asphalt pavement pit repairing patch 100 according to the present invention includes: a first asphalt layer 110 having a first bonding surface 111 and a second bonding surface 112 opposite to each other; a second asphalt layer 120 having a third bonding surface 121 and a fourth bonding surface 122 opposite to each other, wherein the third bonding surface 121 of the second asphalt layer 120 faces the second bonding surface 112 of the first asphalt layer 110; a fabric layer 130 disposed between the second bonding surface 112 of the first asphalt layer 110 and the third bonding surface 121 of the second asphalt layer 120; a crushed stone layer 140 disposed on the first bonding surface 111 of the first asphalt layer 110; and an insulation layer 150 disposed on the fourth bonding surface 122 of the second asphalt layer 120.
The first bonding surface 111 of the first asphalt layer 110 can be the front side of the first asphalt layer 110 and the second bonding surface 112 can be the back side of the first asphalt layer 110. The third bonding surface 121 of the second asphalt layer 120 may be a surface facing the second bonding surface 112 of the first asphalt layer 110, and the fourth bonding surface 122 of the second asphalt layer 120 may be a surface facing away from the third bonding surface 121.
The first asphalt layer 110 and the second asphalt layer 120 play a role of waterproofing in the asphalt pavement pit repairing paste 100, and may be made of any suitable material. For example, the first asphalt layer 110 and the second asphalt layer 120 may be polymer modified asphalt layers formed by mixing and reacting base asphalt, rubber powder, SBS, extract oil, and filler; however, the present invention is not limited thereto, and the first asphalt layer and the second asphalt layer may be formed using any suitable material that satisfies the technical criteria as shown in the following table 1.
TABLE 1 technical index of materials forming the first asphalt layer and the second asphalt layer
According to the asphalt pavement pit repairing paste 100 of the present invention, the fabric layer 130 is positioned between the second bonding surface 112 of the first asphalt layer 110 and the third bonding surface 121 of the second asphalt layer 120 to perform a calendaring function and a deformation resistance function. Fabric layer 130 may be made using any suitable high strength material. For example, fabric layer 130 may be made of alkali-resistant fiberglass mesh cloth or basalt fiber bi-directional cloth; however, the present invention is not limited thereto, and the fabric layer may be made using any suitable material that can satisfy the technical criteria as shown in the following table 2. Here, it should be noted that the alkali-resistant glass fiber mesh cloth can meet the specification of the standard JC/T841, and the longitudinal and transverse directions of the basalt fiber bidirectional cloth can meet the specification of the standard JT/T776.2.
TABLE 2 technical indices of the Fabric layers
| Item | Technical requirements |
| Maximum tensile force, N/50mm | ≥1400 |
| Elongation at maximum tensile force% | 1.0～10.0 |
| Thickness, mm | 2.0±0.5 |
| Mass per unit area, g/m2 | ≥230 |
The thickness of the fabric layer 130 may be 1-2.5 mm. Too small a thickness of the fabric layer 130 may affect the tensile properties of the asphalt surface pit repair patch 100; the excessive thickness of the fabric layer 130 may affect the overall thickness of the asphalt pavement pit repairing paste 100, thereby affecting the flatness of the asphalt pavement.
The fabric layer 130 may be impregnated with a bituminous material. More specifically, the first asphalt layer 110 may be in direct contact with the fabric layer 130 such that the asphalt material is impregnated into the fabric layer 130; the second asphalt layer 120 may be in direct contact with the fabric layer 130 such that the asphalt material is impregnated into the fabric layer 130. In other words, the first asphalt layer 110, the fabric layer 130, and the second asphalt layer 120 may be combined to be formed as one body.
In a non-limiting exemplary embodiment of the present invention, the structure in which the fabric layer 130 is surrounded by the asphalt material, that is, the structure of the first asphalt layer 110, the fabric layer 130, and the second asphalt layer 120, may be obtained by dipping the fabric layer 130 in the asphalt material for forming the first asphalt layer and the second asphalt layer, followed by calendar setting. In an exemplary embodiment of the present invention, the total thickness of the first asphalt layer 110, the fabric layer 130, and the second asphalt layer 120 may be in the range of 2mm to 4.5 mm. If the total thickness of the first asphalt layer 110, the fabric layer 130, and the second asphalt layer 120 is too thin, the asphalt material cannot be completely impregnated into the fabric layer; if the total thickness of the first asphalt layer 110, the fabric layer 130 and the second asphalt layer 120 is too thick, the flatness of the asphalt pavement may be affected.
The gravel layer 140 may be located on the first bonding surface 111 of the first asphalt layer 110, so as to prevent the asphalt layer from directly contacting with the tire of the traveling vehicle, thereby preventing the traveling vehicle from sticking to the wheel and resisting sliding when passing through the asphalt pavement pit repairing paste.
In an exemplary embodiment of the present invention, the crushed stone in the crushed stone layer 140 may have a particle size of 1.18mm to 4.75mm, for example, the crushed stone in the crushed stone layer 140 may use a single particle size of 1.18mm, 2.36mm, or 4.75 mm. The crushed stone layer 140 may be formed by spreading aggregate (e.g., crushed stone) having a grain size of, for example, 2.36mm on the first bonding surface 111 of the first asphalt layer 110. Specifically, after the first asphalt layer 110, the second asphalt layer 120 and the fabric layer 130 are subjected to calendering and shaping and before cooling, a crushed stone spreader is used for uniformly spreading crushed stones with certain particle sizes and certain quantities on the first bonding surface 111 of the first asphalt layer 110; compacting the crushed stones on the first bonding surface 111 of the first asphalt layer 110 to ensure bonding between the crushed stones and the first bonding surface 111; excess crushed stone on the first bonding surface 111 of the first asphalt layer 110 is cleaned. However, the present invention is not limited thereto.
In an exemplary embodiment of the present invention, the coverage of the crushed stone layer 140 on the first bonding surface 111 of the first asphalt layer 110 may be 75% to 95%. If the coverage of the crushed stone layer 140 on the first bonding surface 111 of the first asphalt layer 110 is less than 75%, the crushed stone layer 140 cannot prevent the traveling crane from wheel sticking and slipping when passing therethrough; if the coverage of the crushed stone layer 140 on the first bonding surface 111 of the first asphalt layer 110 is higher than 95%, the comfort during driving is affected.
In addition, the aggregate used to form the crushed stone layer 140 may have the following technical specifications.
TABLE 3 technical indices of aggregate for forming crushed stone layer
The thickness of the crushed stone layer 140 can be 1-5mm, and if the thickness of the crushed stone layer 140 is too thin, the functions of preventing wheel adhesion and skid resistance cannot be achieved; if the thickness of the gravel layer 140 is too thick, the overall thickness of the asphalt pavement pit repairing paste is affected, and the flatness of the asphalt pavement is affected.
The insulation layer 150 is positioned on the fourth bonding surface 122 of the second asphalt layer 120 and covers the fourth bonding surface 122 of the second asphalt layer 120, thereby protecting the second asphalt layer 120 from the outside and facilitating packaging and transportation of the asphalt pavement pit repairing sticker 100. According to an exemplary embodiment of the present invention, the barrier layer 150 may be a polyethylene blown film. The thickness of the spacer layer 150 may not exceed 0.05 mm.
According to an exemplary embodiment of the present invention, the overall thickness of the asphalt pavement pit repairing patch 100 of the present invention may be in the range of 5mm to 8.5mm, and the thickness of the asphalt pavement pit repairing patch after rolling by a vehicle is in the range of 3mm to 4.5mm, so as not to affect the flatness of the asphalt pavement.
