Product features:

1. It adopts special chassis with advantages of strong bearing capacity,low fuel consumption and stable operation.

2. Auxiliary engine with strong power and stable performance realizes the heating when traveling to shorten the operation time and improve the working efficiency.

3. Hydraulic system adopts the unique patent of load sensitive system, imported key components with stable and reliable quality.

4. It can spread aggregate without lifting the hopper, which is convenient to the constructions in culverts, under bridges and at the curves.

5. The whole equipment runs stably and makes uniform spraying. It can flexibly regulate asphalt spray width, fiber spray width and aggregates

spreading width.The asphalt spray volume can be regulated and controlled by control system.

6. Unique patented fiber cutting spraying device with efficient work and uniform spraying.The operation monitoring system ensure the system

runs stably.

7. Asphalt pipeline are all covered by heat oil to ensure the good circulation of asphalt.The special double deck spray bar,rational spray bar circulation and nozzles design guarantee the evenness and precision of spraying.

8. The dual screw charger with auto feeding control system sprays aggregates evenly,continuously and stably.

9. Sound and durable corrosion-resistant insulation layer keeps heat preservation index no more than 12oC/8h.Dual imported burners are adopted,high efficiency, fast heat up speed,auto ignition and temperature control system,stable operation.

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

11. Special on-board controller is adopted in the system with high protection grade,waterproof,dust proof,shockproof and precise control. Equipped with auto-manual control system, which has good security. All kinds of distributing requirements can be done in the cab and rear platform.

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: inclined bucket type, the bottom plate of the hopper is inclined, and the weight of the stone falls when unloading

Aggregate Distribution Device：Spiral Type（0-25mm） stone material→stock bin→Spiral conveyor

（The aggregate size is relatively small and can be used for surface layer and undersealing layer）

This hi-tech equipment is able to combine the systems of asphalt binder spray, fiber spray and aggregates spreading into one entire process.The principle is just like that a piece of protective mesh of high elasticity and high strength is paved between the surface coat (1-coat asphalt+1-coat fiber+1-coat asphalt+1-coat aggregates) and new roadbed, or on the original road surface.This structure effectively improves the comprehensive mechanical properties of sealing coat in tensile, shear, crush resistance and shock resistanc
