Embodiment 1

[0060] Such as figure 1 The reflective and energy-saving pavement structure of a road in a tunnel is shown, including an original soil layer 21, a sandstone layer 22 and a gravel layer 23 laid sequentially from bottom to top, and a rough asphalt concrete layer 24 is laid on the gravel layer 23, A fine asphalt concrete layer 25 is laid on the rough asphalt concrete layer 24, and a reflective layer 26 is laid on the fine asphalt concrete layer 25. The reflective layer 26 is composed of several white ceramic particles with the same shape and particle size, such as figure 2 As shown, the white ceramic particles include a green body 31, the green body 31 has a multi-rhombic surface, a texture layer 32 is formed on the multi-rhombic surface, the surface of the texture layer 32 is covered with a reflective layer 33, and the reflective The surface of layer 33 is covered with a transparent protective layer 34 .

[0061] In this embodiment, the white ceramic particles can be fully emb...

Embodiment 2

[0067] Such as image 3 A method for paving a reflective energy-saving pavement structure of a highway in a tunnel is used for paving any of the above-mentioned pavement structures, and the method includes the following steps:

[0068] Lay the original soil layer 21, sandstone layer 22, gravel layer 23, rough asphalt concrete layer 24, and fine asphalt concrete layer 25 sequentially from bottom to top;

[0069] The road rolling equipment is used to uniformly spread white ceramic particles on the fine asphalt concrete layer 25 , and insert and extrude the white ceramic particles into the fine asphalt concrete layer 25 for rolling to form the reflective layer 26 .

[0070] In this embodiment, after the original soil layer, sandstone layer, crushed stone layer, rough asphalt concrete layer, and fine asphalt concrete layer are paved in sequence, white ceramic particles are spread on the fine asphalt concrete layer by road rollers, and the The rollers of the road equipment roll th...

Embodiment 3

[0072] On the basis of the above examples, if Figure 4 to Figure 10 A road rolling device is shown, the road rolling device includes a fuselage 1, the fuselage 1 is provided with a blanking box 10 for spreading white ceramic particles, and a first wheel frame 2 and a second wheel frame 3 , the first roller frame 2 is provided with a first roller 4, the second roller frame 3 is provided with a second roller 5, and the first roller 4 is connected with a The first moving frame 7, the first cover plate 71 is arranged on the first moving frame 7, the second rolling roller 5 is connected with the second moving frame 8 through the second transmission mechanism, the second moving frame 8 A second cover plate 81 is arranged on it, and the bottom end of the discharge box 10 is closed when the first cover plate 71 and the second cover plate 81 abut against each other. The first rolling roller 4 and the second rolling roller 5 Drive the first moving frame 7 and the second moving frame 8...

Abstract

The invention relates to a road reflective energy-saving pavement structure in a tunnel and a paving method thereof. The pavement structure comprises an original soil layer, a gravel layer, a rubble layer, a coarse asphalt concrete layer and a fine asphalt concrete layer which are sequentially paved from bottom to top, a reflective layer is paved on the fine asphalt concrete layer, the reflective layer is composed of a plurality of white ceramic particles consistent in shape and particle size, each white ceramic particle comprises a green body, the green body is provided with a multi-diamond surface, a texture layer is formed on the multi-diamond surface, the surface of the texture layer is covered with a reflecting layer, and the surface of the reflecting layer is covered with a transparent protective layer. White ceramic particles of the pavement structure can be fully embedded and extruded into skeleton gaps of a fine asphalt concrete layer mixture, the whole pavement structure is combined more compactly after compaction, the rut resistance and the water damage resistance of a pavement are effectively improved, meanwhile the whole reflective effect of the pavement is better, and the reflecting effect of the pavement is more controllable.

Description

technical field [0001] The invention relates to the field of tunnel pavement construction, in particular to a reflective and energy-saving pavement structure of a highway in a tunnel and a paving method thereof. Background technique [0002] The highway in the tunnel is a relatively closed and narrow tubular environment. There is no sunshine and rain in the tunnel as in the general road section outside the tunnel. The temperature is relatively stable throughout the year, with small temperature changes and small temperature differences. However, the humidity inside the tunnel is relatively humid and the groundwater is abundant. The air mobility in the tunnel is small, and the air is easily polluted; there is no sunshine in the tunnel, and it is in darkness all year round, with low visibility. Therefore, the pavement, maintenance requirements and technologies of tunnel pavement are quite different from the pavement structure of general expressway sections. [0003] In recent...
