HOWO Synchronous Sealing Truck
Synchronous gravel seal is to use a special equipment, namely synchronous gravel sealer, to spread the gravel and bonding materials (modified asphalt or modified emulsified asphalt) on the road surface, and form a single layer of asphalt through natural driving. The gravel wear layer, which is mainly used as a pavement surface layer, and can also be used for low-grade road surface layers. The biggest advantage of the synchronous gravel sealing technology is that the bonding material and the stone material are simultaneously laid, and the high-temperature bonding material sprayed on the road surface can be combined with the gravel immediately without cooling, thereby ensuring the bonding material and the stone material. A strong bond between the two.
Synchronous gravel seal has good anti-sliding performance and anti-seepage performance, can effectively cure road poor oil, falling particles, slight cracks, rutting, subsidence and other diseases, mainly used for preventive maintenance and corrective maintenance of roads. As well as improving the anti-slip performance of high-grade roads, this new maintenance technology can be used on both expressways and ordinary roads. More than 95% of roads in France and Europe use synchronous gravel seals for pavement maintenance. In addition, the synchronous gravel seal can also be used as a low-grade road surface layer. In France, more than 40% of the roads directly use the gravel seal as the road surface, and the current use effect is good. Therefore, in the case of insufficient funds for road construction, the use of low-cost synchronous gravel seals as low-grade road pavement is undoubtedly an effective measure to improve the road pavement rate.
1, manual/automatic control enhanced additionally and width, each nozzle can be individually controlled, determinant nozzle free combination, so as to realize arbitrary adjust the width of spray. In the cab for distributing control or the rear of the platform.
2, the automatic control system can measure the speed of the car and according to the input amount of spill cloth and spraying width and asphalt type, automatic calculation of asphalt pump revolution to adjust the asphalt pump pump automatically by the system.
3, vehicular rapid heating system (10-15 ºC / h), can improve the heating efficiency and reduce the auxiliary time of construction, ensure that makes temperature;
4, blunt the nozzle of the system residual asphalt by diesel with high pressure air nozzle can be blown out, prevent asphalt to freeze in the nozzle, improve the service life of the nozzle.

Truck Picture:
Application:
Asphalt distribution truck is widely used in highway construction and highway maintenance engineering. It can be used for the different pavements of upper and lower sealing layer, prime coat, waterproof layer, adhesive layer, asphalt surface treatment, bituminous penetration pavement, and fog sealing layer and other construction. It also can be used for transportation of liquid asphalt or other heavy oils.
