[0026] Reference Figure 1 -3. This utility model provides a crack-resistant asphalt pavement containing self-healing microparticles, comprising:

[0027] The main unit 100 includes a base layer 101, a concrete-aggregate layer 102 on the base layer 101, a reinforcing layer 103 on the concrete-aggregate layer 102, a metal mesh layer 104 on the reinforcing layer 103, an asphalt layer 105 on the metal mesh layer 104, and a wear-resistant layer 106 on the asphalt layer 105. The base layer 101, concrete-aggregate layer 102, reinforcing layer 103, metal mesh layer 104, asphalt layer 105, and wear-resistant layer 106 are arranged sequentially from bottom to top. The asphalt layer 105 contains self-healing microparticles, providing stable support through the base layer 101. The concrete-aggregate layer 102 and reinforcing layer 103 enhance the overall strength. The metal mesh layer 104 improves toughness and prevents pavement cracking. The asphalt layer 105, containing self-healing microparticles, can automatically repair minor damage to the pavement. The topmost wear-resistant layer 106 greatly improves wear resistance, extends pavement service life, and reduces maintenance costs.

[0028] The compression-resistant unit 200 includes multiple rhomboid bending members 201, which are all fixedly connected within the reinforcing layer 103. The multiple rhomboid bending members 201 are distributed at equal intervals laterally. The metal mesh layer 104 is provided with reinforcing components 202. Through the multiple rhomboid bending members 201 distributed at equal intervals within the reinforcing layer 103, the structural strength of the reinforcing layer 103 can be greatly enhanced, effectively dispersing the pressure from the road surface and preventing it from deforming due to heavy pressure.

[0029] The reinforcing component 202 includes multiple arc-shaped plates 202a, which are fixedly connected within the metal mesh layer 104. The multiple arc-shaped plates 202a are arranged in a ring structure. Semi-circular protrusions 202b are fixedly connected to both sides of the multiple arc-shaped plates 202a. The multiple arc-shaped plates 202a enhance the bending and compressive strength of the metal mesh layer 104, making it less prone to deformation when subjected to external forces. The semi-circular protrusions 202b on both sides increase the friction and contact area with the surrounding materials, effectively preventing displacement between materials and comprehensively strengthening the stability of the road structure.

[0030] Furthermore, the concrete crushed stone layer 102 is prepared by crushed stone, cement and water. The concrete crushed stone layer 102 is laid in layers. Each layer can ensure that the materials are tightly bonded. After compaction, the structure is more compact and the load-bearing capacity is effectively improved. The layered operation can also allow the cement to fully hydrate and react, enhance the overall strength, reduce road damage caused by uneven settlement or heavy pressure, and extend the service life.

[0031] Furthermore, the metal mesh layer 104 is composed of multiple high-strength metal plates connected to each other to form a mesh structure. Through the interconnection of multiple high-strength metal plates, the pressure borne by the road surface is evenly distributed, effectively preventing cracks and depressions in the road surface, improving the road's durability, reducing maintenance costs, and ensuring the safety and stability of vehicle driving.

[0032] Furthermore, the asphalt layer 105 also contains lignin fibers, aggregates, and mineral powder. The asphalt layer 105 adopts a double-layer structure. The lignin fibers enhance flexibility and prevent cracking, while the aggregates and mineral powder improve density and wear resistance. The double-layer design increases thickness, strengthens waterproofing and anti-slip capabilities, effectively buffers vehicle loads, reduces noise, and comprehensively improves driving comfort.

[0033] Furthermore, steel fibers are uniformly incorporated into the wear-resistant layer 106. The wear-resistant layer 106 adopts a double-layer composite structure. The steel fibers greatly enhance its toughness and strength, effectively resisting the wear caused by vehicle driving. The double-layer composite structure further strengthens the wear resistance performance. The upper and lower layers work together to disperse pressure and reduce the risk of crack formation.

[0034] During use, the base layer 101 provides stable support, while the concrete crushed stone layer 102 and the reinforcement layer 103 enhance the overall strength. The metal mesh layer 104 improves toughness and prevents road surface cracking. The asphalt layer 105 containing self-healing microparticles can automatically repair minor damage to the road surface. The top wear-resistant layer 106 greatly improves wear resistance, extends the service life of the road surface, and reduces maintenance costs. Meanwhile, the multiple diamond-shaped bending elements 201 evenly distributed within the reinforcement layer 103 greatly enhance the structural strength of the reinforcement layer 103, effectively disperse the pressure from the road surface, and prevent it from deforming due to heavy pressure. The multiple arc-shaped plates 202a improve the bending and compressive strength of the metal mesh layer 104, making it less prone to deformation when subjected to external forces. The semi-circular protrusions 202b on both sides increase the friction and contact area with the surrounding materials, effectively preventing displacement between materials and comprehensively enhancing the stability of the road structure.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
