The use of waste rubber to make rubber powder has great development prospects in China

Every year, China produces several million tons of waste plastic composite materials. If it is not handled as soon as possible, it will cause serious pollution to the environment. At the same time, China is a rubber-short country, and almost 45% of the rubber consumption is dependent on imports. Therefore, the use of waste rubber to make rubber powder has great development prospects in China.

The use of scrap rubber powder for the modification of asphalt has been very mature from theory to practice. The use of scrap rubber powder modified bitumen not only has a low price, but also has better performance than SBS modified bitumen, and has a good prospect for the construction of high-speed or high-grade highways. In China, a lot of work has been done on the modification of waste rubber powder modified asphalt from the modification mechanism to the development and application. A major breakthrough has been made in the development and production of high-grade highway asphalt; in addition, China has made a suitable sprayer for waste rubber modified asphalt. It provides construction supporting hardware for the application of waste rubber powder modified asphalt. Practice has proved that roads covered with rubber-modified asphalt can reduce the cracking and softening of pavements, and the roads are not prone to freezing and slipping. This improves the safety of driving and improves the road life. At least the service life of ordinary asphalt pavements is at least Doubled.
