In recent years, domestic synchronous gravel sealing technology has made rapid progress, and relevant construction experience has become increasingly rich. And it is widely used on roads in my country. This is inevitably inseparable from the advantages of the synchronous gravel seal layer itself.

①Synchronous gravel sealing technology is currently recognized by the world as a low-energy road maintenance technology, that is, it can cover a large area without spending a lot of money. This is very suitable for China as a developing country.
(2) Compared with other technologies such as thin slurry sealing or ultra-thin sealing, the synchronous gravel sealing technology of the synchronous gravel seal vehicle has a longer asphalt softening period and is more suitable for non-rigid pavements. Strong water resistance, high skid resistance, good roughness, and good interlayer crack treatment performance. This is very suitable for the climate characteristics of summer precipitation and long rainy season in most parts of China.
(3)my country has a vast territory and large differences in road conditions. Synchronous gravel sealing technology is suitable for expressways, highways and secondary roads, as well as urban roads, rural and suburban roads, and can cope with different climates, traffic capacities and other conditions.
(4) Synchronous gravel sealing technology is also a low-cost rural road construction technology in the world, and is a good solution for rural road construction. In order to develop road maintenance, a lot of money needs to be invested. If synchronous gravel sealing technology is adopted, a lot of costs can be saved.
