Go Green Color Porous Asphalt Pavement is a new pattern color asphalt paving program based on color asphalt pavement. The surface layer uses OGFC gradation asphalt concrete, which uses Go Green special high viscosity colorless asphalt binder as the bonding material, the voidage is 18%~25% after compaction. The rainwater permeate into the dewatering layer through the surface void, and drain out the water to underearth or to road two sides through the interlamination voids, thus to eliminate surface water films which bring lots driving troubles. It can significantly improve driving safety and comfort in rainy days. According to the structure, Go Green color porous asphalt pavement including semi permeable pavement and full permeable pavement.
Semi permeable color asphalt paving program
The semi permeable color asphalt pavement is consist of porous color asphalt surface layer and waterproof structure later, between the top and bottom porous color asphalt pavement layers, it need to build up the waterproof bonding layer. The rainwater can permeate into the color asphalt pavement through the surface voids, and drain out to two sides along the base layer. This can effectively avoid rainwater permeate into the pavement base structure layer. The water on porous color asphalt surface layer need to flow accessibly to one direction. We can use pre-embedded pipes or drainage ditches to lead water away.
Full permeable color asphalt paving program
Full permeable asphalt paving program don’t need to build waterproof layer under the porous color asphalt pavement. The asphalt bottom layer and base course both use permeable structure, the surface water finally permeate into the base course though the permeable structure layer. This kind of permeable structure can quickly make the rainwater permeate into underground, thus to restore underground water, keep soil moisture and maintain the ecological balance of underground water and soil. The color asphalt paving program is mainly suitable for landscape, square, footpath etc.
1 Good Road Performance
Go Green color porous asphalt pavement uses special OGFG gradation. This kind structure of asphalt mixture make the coarse aggregates connect tightly. Aggregates can form embedded squeeze skeleton with each other. Internal friction and embedded squeeze force between coarse aggregates play a decisive role. This design has better performance to resist rutting under high temperature. The mixture uses Go Green special high-viscosity colorless asphalt binder as bonding material, which ensure the pavement has good water damage resistance and anti-fatigue speciality.
2 Improve Pavement Safety
During rainy days, it can rapidly eliminate the surface hydrops, prevent forming into water film, thus to effectively improve the safety of vehicles and pedestrian.
3 Reduce Traffic Noise
Special open graded structure makes the asphalt pavement voidage reach up to 20%, this reduce the pressure in voids, which can effectively reduce the noise generated by moving non-motorized vehicles due to the air extrusion and pump suction.
4 Adjust Environment
As it has the special pore structure, which its heat absorption and thermal accumulation function are closely to the pavement covered by nature plants. It can efficiently adjust the temperature and humidity of city space and remit urban heat island effect.
5 Maintain the Ecological Balance of Underground Water and Soil
Porous pavement good permeability can make the rainwater quickly permeate into underground, effectively restore the underground water, keep soil humidity and prevent the base course subsidence due to groundwater overexploitation
6 Bright Color With Good Color Stability
Go Green color porous asphalt pavement uses special pigment, which can design to different color pavement according to surrounding environment, widely meet the color requirement for park, square, non-motorized vehicle lane, footpath etc.
