OGFC PAC Porous Grading Ration Drainage Pavement Porous Asphalt Asphalt Additives
| ZTH high-viscosity asphalt modifier that improves the viscosity of asphalt mixture. It is a special high viscosity modifier for permeable asphalt pavement, even suitable for high temperature and heavy load traffic. The method of use directly mix with the aggregates to produce modified asphalt mixture. The asphalt mixture prepared by ZTH high viscosity modifier has the characters of high durability, high temperature stability, low temperature crack resistance, water stability and anti-aging performance, and it has high anti-scattering property, water resistance, weather resistance and resistance to flow. Permeable asphalt pavement is called porous asphalt pavement, also known as low noise asphalt pavement. It has excellent drainage, anti-skid, noise reduction and other functions, and it's a safe and environmentally friendly new technology for ecological asphalt pavement paving. |

1. Water-permeable pavement can effectively avoid water splashing, glare and water drift during rainy driving. 2. Drainage asphalt pavement under moderate rain conditions can increase driving distance recognition distance by more than 2 times. 3. Increase the friction coefficient of the road surface during rainfall and shorten the braking distance. The braking distance of the vehicle at a 4peed of 100km / h is shortened by about 12m compared to ordinary roads. 5. Reduce the traffic accident rate on rainy days by 47%. 6. Reduce the intensity of noise at the source and reduce traffic noise by 5-10 decibels, and it help shape the living environment along the road. Noise reduction is greater on rainy days. The higher the speed, the greater the noise reduction. 7. Save material. The porosity of the permeable pavement is large, paving a pavement with the same thickness as ordinary pavement can save a lot of aggregate and asphalt. 8. Reduce costs. Construction costs are 5-10% lower than SMA roads, and high-end roads are not expensive. 9. Long life performance. Observed in solid engineering for 15 years, the structural strength and drainage function are durable. 10. Patented technology. Ministry of Communications special promotion of scientific and technological achievements, 2012 National Technology Invention Award. 11. Optimal pavement solution. Drainage asphalt pavement is the best pavement form with improved surface quality. |
This product is mainly used in the middle, upper and lower layers of asphalt pavement construction and maintenance engineering. Asphalt pavement construction and maintenance projects with modified technology construction and tight schedule requirements. Long and wide steep slope sections of high-grade highways, curved slope bridge deck pavement, large-pore drainage asphalt pavement pavement, OGFC and other special pavement structural layers. Asphalt pavement works of national and provincial arterial highways with heavy loads and heavy traffic. Freeway entrance and exit, parking lots, municipal roads, intersections and other sections. Asphalt pavement works in heavy-load traffic sections of mining areas and factories. |
