Synchronous gravel sealing technology has broad prospects. Synchronous gravel sealing technology already has mature application experience in Europe and the United States. Likewise, it is completely suitable for the Chinese highway market. The main basis is as follows:

① Compared with other technologies, such as slurry sealing or ultra-thin technology, synchronous gravel sealing technology uses asphalt with a long softening period and is more suitable for non-rigid pavements. It has strong water resistance, extremely high slip resistance, good roughness, and has good performance in treating inter-layer cracks. This is very suitable for the climate characteristics of heavy summer precipitation and long rainy season in most areas of my country.
② Our country has a vast territory and great differences in highway conditions. The synchronous gravel sealing technology is suitable for expressways, first-class highways and second-class highways, as well as urban highways, rural and suburban highways, and can cope with various situations. Such as different climates, transportation capabilities, etc.
③ Synchronous gravel sealing technology is recognized as the world's lowest energy-consuming road maintenance technology, which means it can cover a large area of ??use without spending a lot of investment. This is very appropriate for China as a developing country.
④Synchronized gravel sealing technology is also the world’s lowest-cost rural road construction technology and a solution for rural road construction in Europe and the United States. There are vast areas in China that need to be covered by rural road networks, and the goal of "every town has asphalt roads and every village has roads" has been achieved. According to relevant data, 178,000 kilometers of county and township roads will be built across the country in the next few years. If synchronous gravel sealing technology is adopted, the cost can be reduced by RMB 10 per square meter, which will save construction costs of RMB 12.5 billion. Undoubtedly, in areas where highway construction funds are scarce, especially in the western region, simultaneous gravel sealing technology will be a good solution for rural highway construction.
