This technology can provide the road with an aesthetically pleasing appearance, and can also be used to identify different types of lanes, traffic areas or scenic spots. In general, asphalt color-changing pavement technology can provide beautiful, safe and diverse options for urban roads and special areas, but it needs to be reasonably selected and designed according to specific usage requirements and environmental conditions.

[0004] In this patent, once the asphalt road surface is stained with rain, there will be a certain risk of slipping. The friction coefficient of the road surface is low due to the influence of rain, and the risk of vehicles slipping on wet and slippery roads is high, resulting in low safety of the road surface. Utility Model Content

[0005] In view of the technical problem in the existing patents that once the asphalt pavement is stained with rain, there will be a certain risk of slipping. The friction coefficient of the pavement is low due to the influence of rain, and the risk of vehicles slipping on the slippery pavement is high, which leads to low safety of the pavement. The utility model provides an asphalt color-changing pavement with good anti-skid effect.

[0006] The technical solution adopted by the utility model is: an asphalt color-changing pavement with good anti-skid effect, comprising a base layer, a reinforcement layer, a buffer layer, a color-changing asphalt layer and an anti-skid layer, a molding groove is opened on the top of the color-changing asphalt layer, the anti-skid layer is laid inside the molding groove, and an anti-skid pad is laid on the top of the anti-skid layer, the anti-skid layer and the anti-skid pad can effectively increase the anti-skid performance of the pavement, the molding grooves and the arc-shaped water diversion grooves are arranged alternately, the molding grooves limit the shape of the protective layer, so that the anti-skid layer is neatly arranged on the upper surface of the asphalt pavement, and the anti-skid layer and the asphalt pavement are at the same height.

[0007] Furthermore, an arc-shaped water diversion trough is opened on the top of the color-changing asphalt layer. The arc-shaped water diversion trough is inclined from the middle to both sides, which can effectively collect and guide rainwater, and draw the accumulated water on the road surface to the drainage system on both sides of the road surface, preventing rainwater from accumulating on the road surface, reducing the impact of road water accumulation on driving safety and road damage, and helping to extend the service life of the road surface to a certain extent. At the same time, reducing road surface water accumulation can reduce the risk of vehicles skidding and losing control when driving on rainy days, thereby improving road traffic safety.

[0008] Furthermore, the reinforcement layer is laid on top of the base layer, and the reinforcement layer can effectively enhance the bearing capacity, deformation resistance and durability of the road surface, thereby extending the service life of the road surface and reducing maintenance costs.

[0009] Furthermore, the buffer layer is laid on top of the reinforcement layer, and the buffer layer plays a role in dispersing load, reducing deformation, and improving comfort and drainage performance in the road surface.

[0010] Furthermore, the color-changing asphalt layer is laid on top of the buffer layer, and the buffer layer helps to improve the service life of the road surface and driving comfort.

[0011] Furthermore, the material of the reinforcement layer is asphalt concrete, and the material of the buffer layer is crushed stone. Crushed stone can provide better drainage performance and a certain buffering effect, and is usually used for road construction of secondary roads and rural roads. In addition to crushed stone, rubber particles and cement concrete can also be used as buffer layers.

[0012] Furthermore, the anti-slip layer is colored rubber particles, and the anti-slip pad is made of rubber. The colored rubber particles are usually granular materials processed from waste rubber products and have the following characteristics: wear resistance, pressure resistance, elasticity, weather resistance, environmental protection and anti-slip properties.

[0013] The beneficial effect of the utility model is that compared with the prior art, in the utility model, the anti-skid performance of the road surface is increased by laying an anti-skid layer and an anti-skid mat on the upper surface of the color-changed asphalt layer. The anti-skid layer and the anti-skid mat are both made of rubber. Rubber has good elasticity and anti-skid performance. Adding it to the asphalt road surface can increase the road friction coefficient, thereby reducing the risk of vehicles slipping on wet and slippery roads and increasing the safety of the road surface.
