Standards have not yet put powder on the road for our country made it difficult to promote

Recently, the authority of the rubberworld Web site reported the world's first full application of waste rubber into the road in the UK, said the average per-mile highway can make use of 354,000 tires, tires for the settlement of pollution to provide an effective way. From our country in the 1990s began to tire of the modified asphalt on the highway application of the test, but the slow progress is still tentative. China Rubber Industry Association of comprehensive utilization of waste rubber Branch of the Under-Secretary-General Liu Yuan in an interview with reporters pointed out that the relevant norms, standards have not yet introduced, the powder used in the road also made it difficult to promote our country.

According to Liu Yuan, due to the powder can be significantly modified asphalt road to extend the service life, improve the anti-slippery, reduce noise, and flexibility in the road, without increasing investment costs, in addition to the current use of SBS modified asphalt, but also The beginning of the use of powder. Such as Shenyang Beiling application of the viaduct section of the powder modified bitumen, more than a decade that there were no problems, and in the same period Beiling viaduct on the general road maintenance has been four times. Although Shen and Kazakhstan, the Shenyang-Dalian, Chengdu-Chongqing expressway, such as the number of test sections have been covered with a rubber modified asphalt, but our powder on the road is still in the development of the application of the pilot phase. General domestic only modified asphalt surface, the application of powder ratio is about 18% to 20%, 1,000 meters of road can be tens of thousands of tires, while Japan and other countries have 3 layers of asphalt pavement are modified, Therefore the use of powder ratio is much higher than domestic.

Liu said that as the EU has decided to start in July 2006, legislation to ban the entire landfill and the breaking up after the birth of the tire, so the application of powder to promote a faster pace. It is understood that the British waste of resources and plan of action from the organization in April 2005 began in Britain within the framework of the entire collection of discarded tires, and to provide financial support, and HoldfastLevelCrossings companies on the reprocessing of used tires to carry out a series of applied research work. Just one year after the completion of the world's first full application of waste rubber roads, and through nearly 8 weeks, Duoliang 8,000 vehicles to its early performance of the test. At present, this road has been named HoldFast rubber highway.
