8*4 Gravel Asphalt Synchronous Sealer Truck-Road Maintenance Truck-Chengli Special Purpose Vehicle

Gravel asphalt synchronoussealer truck simultaneously sprays the asphalt binder and spreads the stone aggregate, so that the asphalt binder and the aggregate have the most sufficient contact to achieve the maximum degree of adhesion between them. The time interval between spraying the adhesive and spreading the aggregate is shortened, so that the aggregate particles can be better implanted into the adhesive to obtain more covering area. HOWO 8*4 Gravel asphalt synchronoussealer truck is easier to ensure a stable proportional relationship between the binder and the stone chips, improve the work productivity, reduce the mechanical configuration, and reduce the construction cost. Asphalt pavement has better anti-skid and water-proof performance after simultaneous gravel sealing, which can effectively cure the road hazards such as lean oil, falling particles, slight network cracks, rutting, subsidence, etc.

8*4 Gravel Asphalt Synchronous Sealer Truck

Gravel Asphalt Synchronous Sealer Truck is used for the construction of lower and upper seals on highway pavements, the construction of new and old pavements with abrasion layers, the pavement construction of asphalt pavements, and the spraying of asphalt gravel under special circumstances.

Product feature

The time interval between the falling of asphalt and gravel at the same location does not exceed 1 second, which greatly improves their adhesion;
The asphalt tank and the gravel silo of Gravel Asphalt Synchronous Sealer Truck are loaded on the same chassis, which reduces the cost;
Gravel Asphalt Synchronous Sealer Truck adopt fully automatic computer control, improve the distributing effeciency and quality;
The forward-going work direction increases construction safety, greatly reduces the harm to the person body, and does not have a great impact on the environment.
