The Sinotruk HOWO Construction Sprayer Bitumen Asphalt Distributor Spraying Truck is a specialized heavy-duty vehicle designed for road construction and maintenance. It is primarily used to spray different types of asphalt binders uniformly onto a road surface.

Primary Function: Uniformly spraying hot asphalt, modified asphalt, cutback asphalt, or emulsified asphalt onto a road surface.

Applications: It is essential for road projects such as:

• Creating the prime coat (first layer on the base).
• Applying the tack coat or bond coat (to help layers of asphalt adhere).
• Constructing the upper and lower seal coats and waterproof layers.
• Fog seal and asphalt penetration pavement.
• Some models (synchronous chip sealers) can also spread aggregate chips immediately after spraying asphalt.

The "intelligent" models of the HOWO asphalt distributor are known for high-precision control:

• Intelligent System: Uses a computer control system (often Siemens PLC or similar) with a touch screen in the cab.
• Variable Rate: Automatically adjusts the asphalt pump's rotation speed based on the vehicle's driving speed to maintain a precise and constant spraying volume (e.g., 0.25−4.0L/m2).
• Independent Nozzle Control: Features an array of intelligent nozzles (e.g., 30-36 pcs) that can be controlled individually or in groups to adjust the spraying width precisely (e.g., up to 4.5m or 6m).

• Insulation: The tank typically has a three-layer structure with a thick insulation layer (like rock wool) to minimize heat loss (often ≤1.5−2 
  ∘
   C/h).
• Heating Method: Uses a heat-transfer oil automatic heating system with an imported diesel burner (e.g., Italian burner). This system indirectly heats the asphalt in the tank and circulates through all pipes, the pump, and the spray bar to prevent asphalt solidification and coking.

• Dual Control: Equipped with control systems both in the cab and on the rear operating platform for flexibility.
• Zero-Distance Starting: Modern technology allows for immediate, uniform spraying at the start of a run.
• Cleaning System: Features an automatic cleaning function (often using diesel and compressed air) to clear the asphalt pump, pipes, and nozzles after work.

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.
