1. It adopts HOWO Euro V chassis which has strong power for good construction performance. High configuration cab is chosen make driving more comfortable.

 High-low gear quick shift improve the working efficiency. 

2. Large capacity of asphalt tank improve single operation efficiency.

3. The tank has two imported diesel burners with high efficiency ,fast heat-up speed, auto ignition and temperature control system, stable and safe performance.

4. Large capacity of hopper improve single operation efficiency.It is no need of lifting the hopper to spread 5 m³aggregates,

which realizes operation in height-limit condition,such as bridges and culverts.

5. Hydraulic system takes power from chassis engine with stable environmental performance.

6. It adopts JOHNSON asphalt pump and heat oil pump.They are with good performance,large range of rotation,good sealability and stable flow.



Heating method: the diesel is ignited to heat the burner, and the heat conducting oil is heated through the burner to form the heating of the asphalt tank and the asphalt itself. Heat conduction oil temperature control at about 280 to 350 . The burner automatically stops heating when the heat conducting oil is heated to the temperature set by the computer.

Aggregate Feeding Device: Back push type, there are baffles in the hopper, and the hydraulic system can push the material to realize the unloading purpose

Aggregate Distribution DeviceChute Distribution Device (0-30mm) stone materialstock bindividing plate. (The particle size of stone is relatively large, usually used in sealing layer).


Chute Distribution


Working Principle


Synchronous chip sealer is kind of special equipment used for chip sealing of road surface, bridge waterproof and lower seal coat. It realizes that asphalt binders spray and aggregates spreading perform synchronously, which makes full touch of asphalt binders and aggregates to realize their maximum cohesive performance.

Spraying the fluid asphalt with clean dry aggregates on the road, outside loads formed strength unceasingly. At the same time, because of the surface tension of the liquid asphalt, asphalt climb upward along the stone surface, altitude of about two-thirds of aggregates height, and over the surface of the stone form half moon shape , make stone wrapped by asphalt covering area of about 70%, have sufficient bonding strength.
