Description

Background
With the development of the expressway in China, the abrasion of the asphalt pavement is accelerated by a high speed and a high traffic flow, so that the anti-skid capability of the asphalt pavement is rapidly reduced, and particularly, traffic accidents frequently occur when the anti-skid capability of the asphalt pavement is prominent at an entrance and an exit of a bend, a downhill road and the like.
Therefore, in order to improve the driving safety of people and reduce the probability of traffic accidents, the research on the skid resistance of the asphalt pavement is very important (the overview of the development of the skid-resistant surface layer of the asphalt pavement, namely plum sensitivity, pass, 2016, 9 th year, 90 th page summary, lines 1-4, and 2016, 12 th month, 31 th day).
Road surface anti-sliding consumption layers are arranged on accident-prone road sections such as tunnel exits, curves and downhill road sections and slow-moving road sections needing to be decelerated, road surface roughness can be effectively increased, and functions of deceleration and warning are achieved (the characteristics and application of a colored anti-sliding consumption layer on the road surface, Xiaoyan and the like, the road traffic technology, No. 6 in 2013, No. 2, No. 1-3 in the left column on page 19, and open day 12 and 31 in 2013). The road surface antiskid wearing layer is mainly suitable for paving special road sections such as tunnels, bridges, sharp bends, long downhill roads, ramps, toll stations, expressway entrances and exits and the like and repairing old cement concrete pavements. Compared with the traditional asphalt mixture and cement mixture, the anti-skid wearing layer has the advantages of excellent anti-skid performance, high bonding strength, good wear resistance, thin thickness, light self weight, corrosion resistance, good flame retardance, convenient construction and the like ('the characteristics and the application of a colored anti-skid wearing layer on a pavement', Xiaoyan and the like, a road traffic technology, 6 th in 2013, 1 st line from 5 th section of the left column on the page 19 to 1 st line from 5 th section of the right column on the page 19, and 31 days of 12 months in 2013 on the open day). The schematic diagram of the anti-skid wearing layer is shown in figure 1.
However, most of the existing anti-skid wearing layer materials are normal temperature curing type, and the curing time is usually longer in order to ensure the construction holding time. In addition, the maintenance time of the anti-skid wear layer material using the normal-temperature curing agent is multiplied and the anti-skid wear layer material cannot be quickly opened in winter or severe cold areas, and the anti-skid wear layer material is not suitable for the fields of municipal engineering and the like which need to be quickly opened.
