Synchronous gravel sealing technology, from the 20th century, 80 years in France has been large-scale adoption in the 1990s spread to the whole of Europe and the United States, Russia, India,Asphalt Roller Price Maintenance Africa, Australia and dozens of countries and regions to get Promotion. According to statistics, in Europe more than 95% of the roads are using this technology for conservation.
Application of synchronous gravel sealing technology in China. At present, synchronous gravel sealing technology in China's Liaoning Province, Hunan Province and other places under the highway seal layer and the construction of national highway, provincial highway has been applied. Because of the superior performance of this technology, many highway construction departments have a strong interest to him, but in general, because the technology in China has just begun to be applied,Very powerful Electronic Road Signage advantage many construction techniques have not yet fully grasp, but the lack of construction Experience in the construction of materials on the study is still in the blank, in the synchronization of crushed stone car seal on the study has not yet begun, there are many theoretical and application of the problem is not mastered.
Compared with other technologies such as slurry sealing technology, synchronous gravel sealing technology has strong water resistance, high slip resistance, Beijing has good performance to deal with road cracks, which is very suitable for many parts of China precipitation,Diesel Engines Road Grooving Machine the rainy season Long, mountainous climate characteristics. China's vast region, the road conditions vary greatly, and synchronous gravel sealing technology is applicable to both high-grade highways, but also for general urban roads, rural roads, and not subject to a variety of climate, traffic and other factors. In addition, synchronous gravel sealing technology is a low-energy road maintenance technology, that does not require a lot of investment can cover a large area of use, which is the rapid development of the program is the basis for still in Development stage of China is very suitable.
