Description

Technical Field

[0001] This utility model relates to a road surface structure, and more specifically, to a colored anti-skid road surface structure for tourist highways. Background Technology

[0002] Tourist highways, primarily serving as tourist transportation routes, are roads within their coverage area that possess tourism value or connect tourist attractions. They are comprehensive systems comprised of the highway itself, service facilities, slow-traffic systems, and signage, possessing multiple functions including transportation, landscape, ecology, recreation, culture, and education. As a key product of the deep integration of the transportation and tourism industries, tourist highways not only carry the basic functions of transportation but also serve as important carriers for expanding tourism space, enhancing the tourism experience, and promoting the coordinated development of regional tourism economies. They have become a highly distinctive and promising component of the transportation network.

[0003] For tourist highways, colored pavements have gradually emerged to harmonize the road with the surrounding environment and landscape, and to beautify the driving environment. However, existing colored pavements come in various forms, such as decolorized asphalt pavement, colored sprayed pavement, colored micro-surfacing pavement, colored permeable pavement, and colored anti-skid pavement. Decolorized asphalt pavement involves adding pigments after decolorizing asphalt, resulting in high costs and dull colors. Colored sprayed pavement involves spraying colored pigments onto the road surface, but its color durability is poor and it is usually only used for pedestrian walkways. Existing forms of colored pavement generally suffer from low anti-skid performance and the drawbacks of dull or easily fading pigments, affecting the service life of the colored pavement. Therefore, this paper proposes a colored anti-skid pavement structure for tourist highways. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned technical problems, this utility model provides a colored anti-skid pavement structure for tourist highways.

[0005] This utility model discloses a colored anti-skid pavement structure for tourist highways, comprising a cement-stabilized crushed stone base course and a cement or asphalt concrete base course arranged sequentially from bottom to top. The cement-stabilized crushed stone base course is composed of a mixture of crushed stone and cement, and the cement or asphalt concrete base course is composed of cement concrete or asphalt concrete. The structure is characterized by the following features: above the cement or asphalt concrete base course, from bottom to top, an adhesive layer, a ceramic particle layer, and a surface protective agent layer are arranged sequentially. The adhesive layer is formed by adhesive laid on the cement or asphalt concrete base course; the ceramic particle layer is composed of colored ceramic particles laid on the adhesive layer; the adhesive in the upper part of the adhesive layer penetrates into the ceramic particle layer; and the surface protective agent layer is composed of a transparent topcoat coated on the ceramic particle layer.

[0006] The present invention relates to a colored anti-skid pavement structure for tourist highways, wherein, when the cement or asphalt concrete base is formed by paving with asphalt concrete, an asphalt isolation layer is provided between the cement-stabilized crushed stone subbase and the cement or asphalt concrete base.

[0007] The present invention relates to a colored anti-skid pavement structure for tourist highways, wherein the thickness of the ceramic particle layer is 3cm to 6cm.

[0008] The present invention relates to a colored anti-skid pavement structure for tourist highways, wherein a soil shoulder is provided on the outer side of the cement-stabilized crushed stone base course and on the outer side of the lower part of the cement or asphalt concrete base course. A waterproof geotextile is laid on the top of the soil shoulder and on the top of the end of the cement or asphalt concrete base course, and a sand and gravel layer is laid on the top of the waterproof geotextile.

[0009] The present invention relates to a colored anti-skid pavement structure for tourist highways, wherein a curbstone and a cement strip are laid on top of the sand and gravel layer, and the cement strip is located inside the curbstone.

[0010] The beneficial effects of this utility model are as follows: The colored anti-skid pavement structure for tourist highways of this utility model consists of, from bottom to top, a cement-stabilized crushed stone base course, a cement or asphalt concrete base course, an adhesive layer, a ceramic particle layer, and a surface protectant. The cement-stabilized crushed stone base course and the cement or asphalt concrete base course form a stable roadbed structure. The adhesive in the adhesive layer not only achieves a firm connection with the cement or asphalt concrete base course, but also the adhesive impregnated in the ceramic particle layer achieves a firm fixation of the colored ceramic particles, preventing them from detaching under long-term vehicle pressure. The color of the colored ceramic particles is formed by firing, making it difficult to fade. This contributes to the formation of a durable, high-friction, ceramic particle-resistant, and colorfast colored anti-skid pavement structure for tourist highways.

[0011] Furthermore, when asphalt concrete is used as the base layer for cement or asphalt concrete, an asphalt isolation layer is added above the cement-stabilized crushed stone base layer. The asphalt isolation layer separates the cement-stabilized crushed stone base layer from the cement or asphalt concrete base layer, solving the problem that it is not easy to directly lay asphalt concrete on the cement-stabilized crushed stone base layer.

[0012] Furthermore, by setting up earthen shoulders, waterproof geotextile, sand and gravel layer, curb stones and cement strips in sequence from bottom to top on both sides of the road structure of this utility model, the waterproof geotextile can effectively prevent rainwater from seeping into the earthen shoulders, cement-stabilized crushed stone subbase and cement or asphalt concrete base. The curb stones and cement strips effectively protect the ceramic particle layer and surface protective agent layer, and can effectively prevent their edges from being damaged by vehicle rolling.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 and Figure 2 The diagram shows a schematic and a cross-sectional view of the colored anti-skid pavement structure for tourist highways according to this invention. The colored anti-skid pavement structure for tourist highways comprises, from bottom to top, a cement-stabilized crushed stone subbase 1, a cement or asphalt concrete base 2, an adhesive layer 3, a ceramic particle layer 4, and a surface protective agent layer 5. The cement-stabilized crushed stone subbase 1 is located at the bottom and is composed of crushed stone, cement, and water. After laying, it is compacted to give it good stability and sufficient mechanical properties. The cement or asphalt concrete base 2 is located above the cement-stabilized crushed stone subbase 1 and is composed of cement concrete or asphalt concrete. Thus, the cement-stabilized crushed stone subbase 1 and the cement or asphalt concrete base 2 together constitute a stable roadbed base.

[0019] The adhesive layer 3 is laid on the cement or asphalt concrete base layer 2. The adhesive layer 3 is formed by adhesive and achieves the bonding between the ceramic particle layer 4 and the cement or asphalt concrete base layer 2. The ceramic particle layer 4 is placed on top of the adhesive layer 3. The ceramic particle layer 4 is composed of colored ceramic particles 6. When the adhesive in the adhesive layer 3 is still wet, the colored ceramic particles 6 are immediately and evenly sprinkled with colored ceramic particles 4 with a particle size of 1-3mm to ensure that the colored ceramic particles 4 are fully embedded in the adhesive on the upper part of the adhesive layer 3.

[0020] Because the colored ceramic particles 4 are embedded in the adhesive layer 3, the road surface after paving has good crack resistance. Under various conditions such as repeated vehicle rolling, the colored ceramic particles 4 do not detach and can still maintain the integrity of the structure.

[0021] The surface protective layer 5 consists of a transparent topcoat applied to the ceramic particle layer. This layer protects the underlying colored ceramic particles 6, enhancing their resistance to peeling and effectively ensuring the long-term stability of the road surface's anti-skid performance. Furthermore, because the surface protective layer 5 is transparent, it does not affect the color development of the colored ceramic particles 6.

[0022] In the case where the cement or asphalt concrete base course 2 is made of asphalt concrete, an asphalt isolation layer 7 is provided between the cement stabilized crushed stone base course 1 and the cement or asphalt concrete base course 2. The asphalt isolation layer 7 is formed by pouring liquid petroleum asphalt onto the cement stabilized crushed stone base course 1.

[0023] like Figure 3 The diagram shows a cross-sectional view of the two side edges of the colored anti-skid pavement structure for tourist highways according to this invention. Soil-supported shoulders 8 are provided on both sides of the cement-stabilized crushed stone subbase 1 and on both sides of the upper part of the cement or asphalt concrete base 2. The soil-supported shoulders 8 provide protection and sealing for both sides of the cement-stabilized crushed stone subbase 1 and the cement or asphalt concrete base 2. Waterproof geotextile 9 is laid on the outer and upper surfaces of the soil-supported shoulders 8 and the upper part of the cement or asphalt concrete base 2. The waterproof geotextile 9 effectively prevents rainwater from seeping into the underlying cement-stabilized crushed stone subbase 1 and cement or asphalt concrete base 2, ensuring the stability and durability of the roadbed.

[0024] A layer of sand and gravel 10 is laid on top of the waterproof geotextile 9. The sand and gravel layer 10 has good stability and a higher bearing capacity compared with the soil base used in the earthen shoulder 8. A curb stone 11 and a cement strip 12 are set on top of the sand and gravel layer 10. The curb stone 11 is set on the outside and the cement strip 12 is set on the inside. The upper surfaces of the curb stone 11 and the cement strip 12 are flush with the surface protective agent layer 5. The curb stone 11 and the cement strip 12 protect the sides of the ceramic particle layer 4 and prevent the ceramic particle layer 4 from being damaged under the rolling action of vehicles.

[0025] The construction process of the colored anti-skid pavement structure for tourist highways according to this utility model is as follows:

[0026] 1) Laying of cement-stabilized crushed stone subbase; A certain amount of cement and water are added to the crushed stone, and the mixture is laid on the roadbed. After compaction and curing for 7 days, a cement-stabilized crushed stone subbase with good stability, strong frost resistance and mechanical strength meeting the requirements can be obtained.

[0027] If the cement or asphalt concrete base course 2 is made of asphalt concrete, then an asphalt isolation layer 7 formed of liquid petroleum asphalt is poured on top of the cement stabilized crushed stone base course 1.

[0028] 2) Laying of cement or asphalt concrete base course; Cement should be 42.5 grade silicate, ordinary silicate or road silicate cement, with a water-cement ratio of 0.45:1. Dense fine-grained or medium-grained asphalt concrete can be selected. After laying, compaction and curing should be carried out.

[0029] 3) Laying of adhesive layer; A layer of water-based epoxy resin is poured on the cement or asphalt concrete base layer 2 to form adhesive layer 3;

[0030] 4) Constructing a ceramic particle layer; while the adhesive in the adhesive layer 3 is still wet, evenly spread colored ceramic particles 6 with a particle size of 1-3mm to form a ceramic particle layer 4. The colored ceramic particles 6 are fully embedded in the adhesive, and finally lightly rolled.

[0031] 5) Apply a protective coating layer 5; After the adhesive in the ceramic particle layer 4 has fully solidified, apply a transparent topcoat agent on top of the ceramic particle layer 4 to form a protective coating layer 5.

[0032] 6) Shoulder structure setting; earthwork is laid on the outside of cement-stabilized crushed stone base course 1 and cement or asphalt concrete base course 2, compacted and leveled to form earth-covered shoulder 8; then waterproof geotextile 9 and sand and gravel layer 10 are laid, and finally curbstone 11 and cement strip 12 are laid.
