As the core node of air transportation, the operating efficiency and safety level of airports directly affect the development of the entire aviation industry. During the operation of an airport, the airport runway is one of the key facilities, and its safety, durability and operating efficiency are of vital importance. Existing airport runways are mostly cement concrete roads. Referring to the patent application document with application number CN201010286060.6, a box-type seismic isolation foundation airport pavement structure is disclosed. It consists of a surface layer and a base layer: the surface layer is a concrete pavement, which directly bears the aircraft load and is located at the top; the base layer is a box-type seismic isolation foundation, which plays a load-bearing role and is located at the bottom; the box-type seismic isolation foundation is placed on the foundation, and the concrete pavement is placed on the box-type seismic isolation foundation. The concrete pavement is made of cement and asphalt concrete commonly used in airport pavements.

[0003] The existing cement concrete roads used in airports meet the requirements in terms of pavement strength and load-bearing capacity. However, when encountering low-visibility weather, the runway edge markings are difficult to clearly identify, affecting the safety of aircraft during takeoff and landing. Utility Model Content

To address this technical issue, the present utility model proposes a self-luminous fluorescent surface for airport pavement and an airport road structure.

[0005] The utility model applies self-luminous fluorescent covers to the construction of airport runways, thereby improving the brightness of the airport runways and giving the airport runways self-luminous properties. This can greatly enhance the visibility of the runways at night or in severe weather conditions, thereby improving the safety of aircraft takeoff and landing and reducing the incidence of accidents.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The utility model discloses a self-luminous fluorescent covering for airport pavement, comprising a bonding layer, a fluorescent covering layer and a transparent wear surface layer which are sequentially arranged on the airport pavement base layer from bottom to top along the thickness direction of the airport pavement base layer.

[0008] It is further defined that the bonding layer includes a bottom adhesive layer and an adhesive layer stacked up and down, the bottom adhesive layer is connected to the fluorescent cover layer, and the adhesive layer is connected to the airport pavement base layer.

[0009] It is further defined that the self-luminous fluorescent cover for airport pavement also includes an anti-frustration member, which is arranged between the transparent wear surface layer and the fluorescent cover layer, and one end of the anti-frustration member extends into the transparent wear surface layer, and the other end of the anti-frustration member extends into the fluorescent cover layer.

[0010] It is further defined that the anti-frustration member is an aggregate with a particle size of 0.5 mm to 0.8 mm.

[0011] It is further defined that the self-luminous fluorescent covering surface for airport pavement also includes a reflective element, and the reflective element is placed at the bottom of the fluorescent covering surface layer.

[0016] It is further defined that a plurality of light emitting components are arranged in parallel on each side of the airport pavement.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present invention discloses a self-luminous fluorescent overlay for airport pavement, comprising a bonding layer, a fluorescent overlay layer, and a transparent wear surface layer, arranged sequentially from bottom to top along the thickness of the airport pavement base layer. The present invention applies the self-luminous fluorescent overlay to airport runway construction by placing the fluorescent overlay layer above the airport pavement base layer. This improves runway brightness and imparts self-luminescence, significantly enhancing runway visibility at night or in inclement weather conditions, thereby improving aircraft takeoff and landing safety and reducing the incidence of accidents. Furthermore, the fluorescent overlay material exhibits excellent anti-slip and wear resistance, further enhancing the safety factor of aircraft landing and reducing runway maintenance costs. Furthermore, the present invention provides a transparent wear surface layer above the fluorescent overlay layer. This transparent wear surface layer significantly protects the lifespan of the fluorescent particles in the fluorescent overlay layer, improving the wear resistance of the fluorescent overlay layer and maintaining a long-lasting aesthetic appearance. The bonding layer securely connects the airport pavement base layer and the fluorescent overlay layer.

The bottom bonding layer and the adhesive layer can improve the waterproof performance of the airport pavement base layer, and at the same time improve the firmness of the connection between the fluorescent cover layer and the airport pavement base layer, thereby preventing the fluorescent cover layer from falling off.

[0020] 3. The utility model of a self-luminous fluorescent cover for airport pavement also includes an anti-frustration member, which is used to improve the friction resistance of the fluorescent cover layer and prevent relative sliding between the transparent wear surface layer and the fluorescent cover layer.

[0021] 4. The utility model of a self-luminous fluorescent cover for airport pavement also includes a reflector, which is used to improve the luminous performance of the fluorescent cover.

[0022] 5. The utility model provides an airport road structure, including light-emitting components arranged on both sides of the airport road surface. In rainy weather, the light-emitting components serve as auxiliary to provide additional lighting for the airport road, further improving the safety of the airport road.
