Hope Stone cement pervious concrete pavement with a lower value sand abrasion, opened to traffic after two years pavement skid resistance does not meet the basic regulatory requirements, especially in the rainy and winter, traffic accidents occur frequently. Therefore, improving the ability of cement skid is to ensure that the internal demand "security first" concept of conservation is also an important measure and passengers to protect the safety of life and property. Skid performance degradation causes and treatment methods: cement concrete pavement skid factors. For cement concrete pavement was opened operations, cement concrete pavement skid resistance is an important factor affecting performance of cement concrete pavement. Over time, the vehicle rolling tires wear a lasting effect on its surface texture structure, leading to its skid performance. The main factors affecting the skid resistance for two reasons: First, the surface roughness of the surface roughness of the main factors affect the coefficient of friction, surface roughness of the road surface hinder the formation of a water film, and the tires touch the ground area increased, thereby increasing the lag The friction resistance; the second is the extent of wet pavement, cement concrete pavement under dry conditions, the friction coefficient is large, wet conditions, due to the water molecules in between the tire and the road surface, form a lubricating film of water, deadening the tire and the contact between the road surface, the friction coefficient is relatively small at this time. Survey results show that the traffic police, in the rain and damp when the probability of occurrence of large accidents, it can Qualitatively speaking, the advantages of humidity cement pervious concrete: 1. When concentrated rainfall can reduce the burden on urban drainage facilities to prevent the river who mention flooding and pollution. 2. allow rainwater into the ground quickly, reducing groundwater, soil moisture retention. 3. Prevention of Road area of ??water, the night is not reflective, increase road safety and traffic comfort. 4. Adjust the temperature and humidity of urban space, improve urban heat circulation, ease the heat island effect. 5. The large porosity can reduce road noise when driving the vehicle, creating a comfortable traffic environment. 6. The city can absorb a lot of voids contaminants (such as dust), to reduce dust pollution. 7. Easy to maintain, the gap will not be damaged and difficult to jam. 8. The pattern can be designed to fully and surroundings tuberculosis. Scope: Municipal trails, garden paths, city squares, upscale residential district, parking, business office, outdoor sports (badminton venue, the basketball venue, etc.).
