A
All operations can be performed in the cab.
B
Asphalt spraying rate: 0.2 – 3 kg/m²
C
Adjustable spraying width. Each nozzle is independently controlled; maximum width reaches 6 meters.
D
Very even asphalt spraying with three-overlapping spray capability.
E
Asphalt application rate is computer-controlled and independent of truck speed.
F
Heating and heat-preserving systems use full thermal oil circulation — safe, reliable, and fully automatic.
G
Thermal oil preserves heat in the asphalt pump and nozzles. No diesel flushing needed after spraying. High-pressure air or thermal oil cycling prevents pipeline and nozzle blockages.
H
Modular control system design ensures convenient maintenance and easy troubleshooting.
I
Equipped with a standby control system for continuous operation reliability.
J
Ensures normal machine operation even when the main control system fails.
K
Equipped with a flexible hand-spraying system for manual operation.
L
Excellent heat preservation with average temperature drop less than 1°C/h.
M
Convenient asphalt loading/unloading — via manhole filling, self-pump suction, or self-pump draining.

Frequently Asked Questions
Q
What is the asphalt spraying rate range of this machine?
A
The asphalt spraying rate ranges from 0.2 to 3 kg/m², which can be precisely adjusted and controlled by the onboard computer system independent of truck speed.
Q
Can the spraying width be adjusted, and what is the maximum width?
A
Yes, the spraying width is fully adjustable. Each spraying nozzle can be independently controlled, and the maximum spraying width can reach 6 meters.
Q
How does the thermal oil heating system work, and is it safe?
A
The heating and heat-preserving system introduces full circulation of thermal oil, making it safe, reliable, and fully automatic. Thermal oil also preserves heat in the asphalt pump and spraying nozzles without requiring diesel flushing after use.
Q
What happens if the main control system fails during operation?
A
The machine is equipped with a standby control system that automatically ensures normal operation even when the main control system encounters a failure, minimizing downtime on the job.
Q
How is asphalt loaded and unloaded into the tank?
A
Asphalt loading and unloading is highly convenient. In addition to filling through the manhole, asphalt can be sucked into the tank or drained using the machine's own pump.
Q
How is the pipeline and nozzle blockage prevented?
A
The system uses high-pressure air to drain the pipes and nozzles, or utilizes thermal oil cycling to maintain clear flow paths. This effectively prevents pipelines and spraying nozzles from becoming blocked after each use.
