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.
