Synchronous gravel seal in Europe and the United States has a mature application of technical experience, the same, it is also fully suited to China's road market. Compared with other technologies such as slurry seal or ultra-thin technology, synchronous gravel sealing technology using softening period of long asphalt, more suitable for non-rigid pavement. Has a strong water resistance, high slip resistance, good roughness, and has a good performance between the layers of cracks. This is very suitable for most of China's precipitation and rainy season and long climatic characteristics.Road Repair Machines

Synchronous gravel sealing technology is also the world's lowest cost of rural road construction technology, Europe and the United States is the preferred solution for the construction of rural roads. China has a large area by the rural road network to cover, in order to achieve the "rural through oil, village roads" target. According to the information, the next three years the country will build a new county road 178,000 km, such as the use of synchronous gravel seal technology, per square meter can reduce the cost of 10 yuan, which will save construction costs 12.5 billion. Undoubtedly, in the western region where the road construction is scarce, the simultaneous gravel sealing technology will be a good solution for rural road construction.

In short, the important innovation of road maintenance technology - synchronous gravel sealing technology, is a kind of technology with good cost-effectiveness and maintenance performance. It is suitable for all kinds of highway, traffic and climatic conditions, which can help solve the problem Most of the problems, it will have a broad application in China, China's road construction and conservation in the cause of play a huge role.
