Description
Technical Field
The invention relates to the technical field of asphalt concrete, in particular to reflective anti-vehicle-mark asphalt and a preparation method thereof.
Background
At present, in order to improve the visibility of a road surface at night and enable a driver to drive safely, glass beads are often added into asphalt concrete, and the light reflection characteristic of the glass beads can improve the brightness of the road surface under the irradiation of street lamps, car lamps and even weak moonlight at night. Asphalt pavement occupies a considerable proportion of highways due to its excellent service performance. However, in recent years, due to the limitations of the performance of the raw materials of the asphalt pavement, the increase of traffic volume and heavy-load overloaded vehicles, ruts appear to deteriorate the flatness of the pavement and cause other diseases such as net cracks, pits, holes and the like, and if the damage cannot be controlled in time, the ruts will be spread and cracked under the action of the outer load, so that the service life of the pavement structure is influenced, and the structure of the whole pavement is damaged.
Photo-oxidative aging is the main cause of long-term aging of asphalt roads. Ultraviolet energy exceeds the energy of broken bonds, and weak chemical bonds in asphalt molecules are broken to generate chemical reaction, so that the molecular structure is changed, and the performance is reduced. A large amount of condensed ring compounds, SBS modifiers and the like in the asphalt have strong ultraviolet absorption capacity, and undergo photolysis reaction to cause aging, thus influencing the service performance and the service life of roads. In western regions such as Xinjiang and Tibet in China, the altitude is high, the air is thin, the ultraviolet absorption radiation is particularly strong, the ultraviolet aging phenomenon can cause the temperature crack resistance and fatigue failure resistance of the asphalt pavement to be reduced, the pavement is easy to generate diseases such as cracks, pits and the like, and the service life of the asphalt pavement is shortened.
