synchronous gravel sealing

Synchronous gravel sealing in road maintenance can quickly improve road driving performance, repair anti-skid performance, smoothness, etc. It is used in preventive maintenance and is also one of the methods of low-grade road pavement construction. Synchronous gravel seal has the advantages of high strength, rough surface, non-slip, impermeable, good durability, and prevention of water mist when driving on rainy days. The so-called synchronous gravel sealing layer is to use special equipment, namely the synchronous gravel sealing truck and the bonding material (modified asphalt or modified emulsified asphalt) to be spread simultaneously on the road surface, and the single layer of asphalt wear is formed by natural driving or rolling with a road roller. layer, mainly used as asphalt surface layer.

Synchronous gravel sealing technology refers to the use of special synchronous gravel sealing truck equipment to lay and roll prepared gravel, asphalt and other materials to build a single layer of asphalt gravel wearing layer, which is important for highway pavement. protection of. From the perspective of characteristics, it is simple and easy to implement. It has obvious effects on the prevention of highway diseases, problem solving, later maintenance, and improvement of grade protection. It can also well extend the service life of highways.
