Abstract

The invention aims at providing a tunnel bituminous pavement light color functional layer based on a light color cement material. The functional layer is characterized by comprising the light color cement material and a broken stone material, wherein the light color cement material is formed by mixing a component A and a component B in a mass ratio of 1:1, wherein the component A and the component B have specific compositions. The tunnel bituminous pavement light color functional layer based on the light color cement material has excellent track-resisting capacity and water damage resisting capacity; and the drawing and bonding strength of the light color cement material is obviously improved, the adhesion between the light color cement material and the stone material is improved further, so that the functional layer has more excellent structural integrity and road surface functionality.

Description

technical field [0001] The invention relates to pavement materials and structures for tunnel pavement engineering, in particular to a bright-colored functional layer of tunnel asphalt pavement based on bright-colored cement. technical background [0002] The road tunnel is a relatively closed, 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] The techn...
