（1）Material difference ① Asphalt color-changing pavement: Usually a mixture of decolorized asphalt and pigment is used, or a color-changing agent is used.② Colored anti-skid pavement: Mainly uses MMA color adhesive mixed with colored ceramic particles. （2） Construction difference ① Asphalt color-changing pavement: The construction method is relatively simple. The color-changing agent is sprayed on the original black asphalt pavement. The decolorized asphalt is mixed with various colored stones, pigments and additives at a specific temperature, and then spread and rolled to form a colored asphalt pavement with certain strength and road performance.② Colored anti-skid pavement: No mechanical equipment is required during construction. The colored adhesive material is poured on the asphalt pavement or concrete pavement, and a scraper is used to scrape and smooth it. When it is not dry, the anti-skid particles are sprinkled and embedded in the adhesive. After cooling, the excess particles are swept away. The thickness is generally between 2-3 mm. （3）Performance difference ① Asphalt color-changing pavementAnti-skid performance: The anti-skid value is similar to that of ordinary pavement, and the anti-skid effect is limited.Service life: Generally, the service life is short, and the service life of non-motorized vehicle lanes is not less than 6 to 8 years, and that of motor vehicle lanes is not less than 3 to 4 years.Aesthetics: Bright colors, can be freely matched with various colors and patterns, and has strong ornamental value.② Colored anti-skid pavement:Anti-skid performance: The anti-skid value can reach 85, which is a high anti-skid product, which can greatly shorten the braking distance of motor vehicles, has good water dispersion and reduces splashing.Service life: It has a long service life and can effectively extend the service life of the pavement.Aesthetics: Bright colors, even distribution, anti-oxidation, anti-ultraviolet, no powdering, no fading, and good weather resistance. （4）Application scenarios ① Asphalt color-changing pavement: Asphalt color-changing pavement is suitable for occasions where the pavement color needs to be changed but the anti-skid requirements are not high, such as urban roads, park sidewalks, community trails, etc.② Colored anti-skid pavement: widely used in places that require high anti-skid performance, such as entrances and exits of underground parking lots, crossroads, pedestrian walkways, overpasses, highways, tunnel entrances and exits, and bus stops. In summary, asphalt color-changing pavement and colored anti-skid pavement have significant differences in materials, construction methods, performance, and application scenarios. Colored anti-skid pavement is superior to asphalt color-changing pavement in anti-skid performance and service life, but the construction cost may be higher.

What is colored anti-skid pavement? Colored anti-skid pavement is a new pavement beautification technology that can make traditional black asphalt concrete and gray cement concrete pavements more pleasing to the eye through color construction, while also having an anti-skid effect.   It has high friction and strong anti-skid properties, can effectively shorten the braking distance and prevent vehicles from skidding; it has the effect of pavement color warning and vibration warning, and the construction is simple and fast with a short cycle. Where is colored anti-skid pavement mainly used？ Colored anti-skid pavement is suitable for urban trunk roads, urban secondary trunk roads, urban overpasses and sidewalks, community roads and parking lots, etc.

The significance of permeable concrete pavement Permeable concrete can make rainwater quickly penetrate into the surface, effectively replenish groundwater, alleviate the urban heat island effect, and protect the city's natural water system from damage. It has strong environmental value. At the same time, it solves the problem of easy water accumulation on ordinary roads, improves walking safety and comfort, and is also of great significance for improving the living environment. Permeable concrete subverts its single gray color while retaining the characteristics of traditional concrete. Different colors can be used to integrate the ground with buildings and landscapes to create a warm and harmonious living environment! Characteristics of permeable concrete pavement ① High permeability: Permeable floor has 15%-25% pores, which can make the water permeability rate reach 31-52 liters/meter/hour, which is much higher than the discharge rate of the most effective rainfall under the best drainage configuration.② High bearing capacity: According to the appraisal of the national testing agency, the bearing capacity of the permeable floor can fully meet the bearing standard of C20-C25 concrete, which is higher than the bearing capacity of general permeable bricks.③ Decorative effect: The permeable floor has a color optimization ratio scheme, which can cooperate with the designer's unique creativity to achieve the decorative style required by different environments and personalities. This is difficult to achieve with general permeable bricks.④ Easy maintenance: The pore blockage problem that people are worried about is unnecessary. The unique permeable paving system makes it easy to solve it by high-pressure water washing.⑤ Freeze-thaw resistance: Permeable pavement has stronger freeze-thaw resistance than general concrete pavement, and will not be affected by freeze-thaw and fracture, because its structure itself has larger pores.⑥ Durability: The durability and wear resistance of the permeable floor is better than asphalt, close to ordinary floor, avoiding the shortcomings of general permeable bricks such as short service life and uneconomical.⑦ High heat dissipation: The low density of the material itself (15-25% of the voids) reduces the ability to store heat. The unique pore structure allows the lower underground temperature to be transmitted to the ground, thereby reducing the temperature of the entire paved surface. These characteristics make the permeable paving system close to the ground covered with natural vegetation in terms of heat absorption and heat storage functions.
