Description

Technical Field

[0001] This utility model relates to the field of flooring, specifically to a color-changing topcoat flooring for road surface modification. Background Technology

[0002] Colored pavement is a special type of pavement with color marking function, constructed by adding pigments such as white, red, green, and yellow to asphalt or concrete mixtures, or by using colored aggregates, transparent resins, and other materials [1-2]. Its technical types include five categories: surface coating with coloring materials, decolorized asphalt coloring, and colored aggregate compaction processes. Inorganic pigments (such as iron oxide red and chrome green) are used to improve weather resistance. This type of pavement serves functions such as defining traffic zones (e.g., bus lanes, pedestrian crossings), accident warnings (red danger zones), reducing driver fatigue, and beautifying the urban environment.

[0003] The existing technology has the following problems:

[0004] Ordinary colored topcoat paint is applied directly to the road surface, relying on the chemical adhesion of the paint itself. Under the repeated crushing and shearing action of sun exposure, rain, freeze-thaw cycles, and vehicle tires, this adhesion is easily damaged, causing the paint film to peel off in pieces, affecting the appearance and service life. If the interlayer bonding of multi-layer road structures is not good, slippage and separation can easily occur under load, resulting in cracks and displacement of the surface layer. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] To address the technical problems existing in the background art, this utility model proposes a road surface color-changing topcoat floor, which has the characteristics of improving the road surface forming effect and stabilizing the interlayer bonding of multi-layer road surfaces.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides a road surface color-changing topcoat floor, including protective frames symmetrically arranged on both sides of the road surface, a soil layer sandwiched between the two protective frames, and a concrete base layer laid on top of the soil layer;

[0009] An aggregate layer is laid on top of the concrete base layer, and a leveling layer for leveling is laid on top of the aggregate layer.

[0010] The top of the leveling layer is provided with a paint layer, and the surfaces on which the two adhere are provided with granular protrusions and concave portions.

[0011] Preferably, a floor structure is sandwiched between the two protective frames, and the thickness of each sandwiched layer is the same.

[0012] Preferably, the soil layer has a "slope" structure that slopes and dips from the end to the middle, and the aggregate layer is laid on the clamping area of ​​the soil layer.

[0014] Preferably, the surface layer of the aggregate layer is a granular surface layer, and the slurry of the leveling layer partially penetrates into the gaps in the surface layer of the aggregate layer.

[0015] Preferably, the paint layer is applied to the upper layer of the leveling layer, and the protrusion of the paint layer contacts the leveling layer, forming a concave portion in its contact layer.

[0016] Preferably, the paint layer is a topcoat, and different colors of topcoat are applied to the surface of the leveling layer.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-4 As shown, the present invention proposes a road surface color-changing topcoat floor, which includes protective frames 1 symmetrically arranged on both sides of the road surface, a soil layer 2 sandwiched between the two protective frames 1, and a concrete base layer 3 laid on top of the soil layer 2.

[0026] An aggregate layer 4 is laid on top of the concrete base layer 3, and a leveling layer 5 for leveling is laid on top of the aggregate layer 4.

[0027] A paint layer 6 is provided on the upper part of the leveling layer 5, and the surfaces on which the two adhere are provided with granular protrusions and concave parts.

[0028] It should be noted that: the two protective frames 1 hold the ground structure between them, and the thickness of each layer they hold is the same; the two symmetrical protective frames 1 can act as the template for the road surface, and the height of the protective frames provides a thickness control benchmark for each layer of paving, ensuring that each layer of material filled in can reach the thickness required by the design.

[0029] In this embodiment, the floor is a multi-layer composite structure from bottom to top. The aggregate layer 4 and the leveling layer 5 are anchored and interlocked. The raised and recessed parts of the leveling layer 5 and the paint layer 6 are anchored together. The strength of the interlayer composite is effectively improved, preventing interlayer separation and paint peeling. Because of its strong interlayer bonding, the durability of the paint layer 6 on the floor surface is effectively improved.

[0030] Furthermore, the surface of aggregate layer 4 is a granular surface layer. The upper surface of aggregate layer 4 is a porous and uneven interface formed by exposed granular materials, which serves as a bonding interface for leveling layer 5. Part of the slurry in leveling layer 5 penetrates into the surface gaps of aggregate layer 4. During construction, when the slurry is spread on aggregate layer 4, under the action of gravity and construction pressure, the slurry will flow downward and penetrate into the granular gaps on the surface of aggregate layer 4. After leveling layer 5 is cured, its lower part is anchored into aggregate layer 4. The improved interlayer bonding strength can prevent subsequent interlayer separation.

[0031] Furthermore, the paint layer 6 is applied on top of the leveling layer 5. The paint layer 6 contacts the raised parts of the leveling layer 5, forming a concave part in its contact layer. Before the leveling layer 5 is fully cured, granular raised parts are pre-pressed on its surface. The paint layer 6, as a filler material, applies liquid colored topcoat paint to the leveling layer 5 with the raised structure. The paint will naturally flow and wrap around these raised parts, forming an interlocking between the concave and raised parts. When the topcoat paint is cured, the paint that originally wrapped the raised parts is cured into a concave part that complements its shape. The two layers form a three-dimensional interlocking structure through planar contact, effectively resisting horizontal shear stress and preventing the paint layer 6 from detaching. Since the adhesion problem is solved, the colored paint layer 6 is no longer easily damaged.

[0032] In one embodiment, the paint layer 6 is a topcoat, which is a high-performance coating, typically based on resins such as epoxy, polyurethane (PU), acrylic, or methyl methacrylate (MMA). It has the following properties: high abrasion resistance, weather resistance, and chemical corrosion resistance. Different colors of topcoat are applied to the surface of the leveling layer 5 to indicate functional zoning, safety management, traffic guidance, and information prompts.

[0033] In one embodiment, the soil layer 2 is a "slope" structure with an indentation at the end towards the middle, similar to a "V" shape with a low middle and high sides. The aggregate layer 4 is laid on the clamping area of ​​the soil layer 2, which can actively guide water flow and prevent water from staying inside the ground.

[0034] Among them, soil layer 2, concrete base layer 3 and aggregate layer 4 are all hydrophobic structures with micropores, which allow water to pass through their pores quickly and prevent water from seeping into each layer. The liquid transport direction is from top to bottom. After water seeps into the joints or micropores of the outermost paint layer 6, it will not spread laterally, but will pass vertically downward through the pores of leveling layer 5, aggregate layer 4 and concrete base layer 3 under the action of gravity, and quickly reach soil layer 2. The water that seeps into soil layer 2 will be collected along its preset "slope" structure to the drainage blind pipe or collection well pre-buried in the middle, and finally be actively discharged from the entire road surface structure.

[0035] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
