According to the invention, the force induction material and the reinforcing agent are added into the decolored asphalt, so that the road surface is yellow when no vehicle runs; when a vehicle runs, the road surface is blue.

Description
Technical Field
The invention belongs to the field of asphalt pavement materials with special functions, and particularly relates to a mechanochromic asphalt material for an asphalt pavement in a tunnel and a preparation method thereof.
Background
The tunnel pavement is in a closed environment, lacks of sunlight and has poor brightness, so that a bright environment outside a tunnel easily forms huge contrast, so that a driver visually generates 'dark adaptation' and 'bright adaptation' when a vehicle enters or exits the tunnel, transient visual disturbance is generated, and driving safety is influenced. Although the effect is poor due to the fact that illumination is enhanced in the tunnel, a large amount of energy is consumed, the occurrence of traffic accidents is not reduced, and particularly, great hidden dangers exist in driving safety of (extra) long tunnels. Therefore, many researchers turn their attention to the research of luminous asphalt pavement, and at present, there are three main types of high-brightness coefficient asphalt pavement paving materials: aggregate with high light reflectivity such as silica, granite, dolomitic limestone and dolomite) which has a light color, and most incident light rays are reflected to show high surface brightness when the light rays irradiate the surface; secondly, the surface reflection brightness of the pavement is improved by utilizing the retro-reflection characteristic of the glass material to light rays by using glass crystal materials such as waste glass, glass beads and the like; thirdly, the luminous stone or luminous powder is scattered on the surface of the asphalt concrete during the construction of the asphalt pavement and is combined with the asphalt concrete into a whole. The light energy emitted by the automobile lamp is absorbed in a short time, so that the diffused fluorescence can be emitted for a long time, and the aim of tunnel illumination is fulfilled.
The three types of asphalt luminous asphalt pavements commonly used at present are not good in effect through a small range of practical engineering application. Among them, the asphalt pavement which emits light by means of light reflection has a defect that the light-emitting time is too short; the asphalt pavement which depends on the automobile lamp to emit the diffused fluorescence is easy to generate the fluorescence quenching phenomenon, and the luminous effect is poor.
The defects of poor luminous efficiency and short storage time of the luminous asphalt pavement in the tunnel at present are overcome. The invention provides a mechanochromic asphalt material for an asphalt pavement in a tunnel. The material is compounded by adopting the decolored asphalt and the mechanoluminescence material, and the asphalt material presents yellow phosphorescence under the unstressed condition; when vehicles pass through the road surface asphalt material, the asphalt material on the road surface is under the action of pressure and friction force, and the asphalt material presents strong blue light. The mechanochromic asphalt material realizes conversion luminescence between yellow and blue, greatly improves the luminous efficiency, has higher intensity, has long luminescence duration and does not have quenching phenomenon. Is a luminous pavement material with application prospect and market value.
