[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0019] Please refer to Figs. 1-2 The biological enzyme enhanced soil roadbed and concrete surface layer composite structure in the embodiment includes bottom base layer 1, the upside of bottom base layer 1 is paved with base layer 8, the upside of base layer 8 is paved with crack resistance layer 2, the upside of crack resistance layer 2 is paved with leveling layer 7, the upside of leveling layer 7 is paved with concrete surface layer 6, the upside of concrete surface layer 6 is paved with wear layer 5, the upside of wear layer 5 is paved with waterproof layer 4, and the upside of waterproof layer 4 is paved with drainage layer 3.

[0020] The anti-cracking layer 2 is rubber particle asphalt mixture, the drainage layer 3 internally contains gravel particles and pervious concrete, the waterproof layer 4 internally contains polyethylene geomembrane and asphalt waterproof roll material, the wear-resistant layer 5 internally contains epoxy resin and wear-resistant aggregate, the bottom base layer 1 internally contains biological enzyme soil stabilizer, the base layer 8 internally contains biological enzyme soil stabilizer, the leveling layer 7 internally contains cement mortar or fine stone concrete, and the concrete surface layer 6 is high-strength concrete material.

[0021] It should be noted that the bottom base layer 1 is the lowermost layer of the roadbed, and the bottom base layer is usually made of natural soil or soil material after preliminary treatment. In the biological enzyme enhanced soil roadbed, the bottom base layer is added with biological enzyme soil stabilizer for stabilization treatment to improve its strength and stability. The base layer 8 is located above the bottom base layer 1 and is the main layer to bear the load of the road surface. The base layer material is usually selected from soil or soil mixture with good bearing capacity and stability, and is added with an appropriate amount of biological enzyme soil stabilizer for stabilization treatment. The anti-cracking layer 2 prevents cracks in the concrete surface layer due to temperature changes, load effects and other factors to improve the anti-cracking performance and durability. The drainage layer 3 has good water permeability and bearing capacity, which can effectively drain the accumulated water in the road surface structure to improve the drainage efficiency and bearing capacity. The waterproof layer 4 has good waterproof performance and durability, which can effectively protect the roadbed from water erosion to improve the waterproof performance and durability. The wear-resistant layer 5 has good wear resistance and skid resistance, which can effectively prolong the service life of the road surface to improve the wear resistance and skid resistance.

[0022] The working principle of the above embodiment is as follows:

[0023] The wear-resistant layer 5 poured on the upper side of the concrete surface layer 6 increases the wear resistance and skid resistance of the road surface, improves the driving safety, and prolongs the service life of the concrete surface layer 6 and the bottom base layer 1. The laid waterproof layer 4 can improve the waterproof performance and durability. At the same time, biological enzyme stabilizer can be added to the waterproof layer to enhance the bonding force and overall performance of the waterproof layer and the roadbed. The drainage layer 3 improves the drainage efficiency and bearing capacity. For example, pervious asphalt mixture with higher water permeability can be used as drainage layer material, or multi-layer drainage structure can be used to enhance the drainage effect. The bottom base layer 1 is added with biological enzyme soil stabilizer for stabilization treatment to improve its strength and stability. The anti-cracking layer 2 is added with an appropriate amount of biological enzyme soil stabilizer for stabilization treatment.
