The newly renovated Zhengzhou-Luoyang Highway in Henan Province debuts on 29th September. What's so special about it is that parts of the highway have been coated with a colorful layer of high tech materials as seen in the photos above.
The coating is a mixture of resin glue and ceramic particles, and the function of the coating is to increase friction on the road surface and hence better safety in rainy seasons. Noise reduction is another useful feature. The bright colors also serve to attract drivers' attention. The coatings are concentrated primarily in accident-prone areas such as downhill paths, entrances and exits of tunnels.
The coated surfaces add up to about 30,000 meters square. If this concept is taken well by the public, the Henan government is planning to do more of it.
