Sinotruk Howo 16000liters asphalt distributor sprayer Cambodia

Name: Sinotruk Howo 16000liters asphalt distributor sprayer Cambodia
Brand: Sinotruk HOWO

The Sinotruk HOWO 16000 litre asphalt distributor sprayer is a 6x4 truck built on a second-hand HOWO chassis for road construction projects requiring precise, consistent application of emulsified asphalt, fluxed asphalt, heated asphalt, and high viscosity modified asphalt. It is used by road contractors and municipal agencies in tropical and semi-arid regions where surface preparation and seal coating must be completed quickly and uniformly under high ambient temperatures. The truck delivers asphalt at controlled rates across a spray width of 2 to 6 metres, with full operation from the cab or a post-operational platform.

Buyer Profile

Who It Is for

Road construction and maintenance contractors in developing markets
Municipal public works departments managing rural and urban road networks
Government road agencies overseeing national highway rehabilitation projects
Private contractors bidding on infrastructure tenders requiring asphalt application equipment
Road asset managers responsible for preventive maintenance of asphalt pavements

Operating Problems

Problems It Solves

Inconsistent spray patterns from manual or outdated distributors leading to over-application or missed spots
Frequent nozzle clogging due to asphalt cooling or residue buildup during long operations
Lack of temperature control causing asphalt to thicken or degrade before application
Need to stop and refill too often due to small tank capacity on low-capacity spreaders
Manual operation requiring multiple crew members and increasing labour costs
Inability to adjust spray width on the fly, forcing rework or multiple passes

Where It Works

Application Scenarios

Pavement sealing operations on rural and secondary roads with limited access to asphalt plants
Rehabilitation of cracked asphalt surfaces in tropical climates where rapid curing is required
Construction of new road sections in remote areas with no nearby asphalt batching facilities
Maintenance of high-traffic urban roads requiring frequent seal coats to prevent water infiltration
Road upgrading projects in Cambodia and Southeast Asia where consistent spray patterns reduce material waste
Contractors working under tight schedules who need a reliable, low-maintenance asphalt distributor

Insulated tank walls with heat conduction oil circulation system

How It Is Built

Manufacturing Process

Chassis is received from CNHTC Jinan Truck Co., Ltd. and inspected for frame alignment and driveline integrity
Tank is pressure tested and coated with anti-corrosion primer before installation
Pump, heating system, and piping are assembled and tested for leaks and flow rate
Computer control system is installed and calibrated with individual nozzle response checks
Spray nozzles and blowing system are tested under full pressure with simulated asphalt
Cab and rear platform controls are synchronized and tested for fail-safe operation
Final assembly includes fitting of tyres, rear platform, and safety signage
Truck is tested on the factory apron with full load and spray cycle before delivery

Testing

Quality Control

Every truck is 100 percent tested before delivery
Tank and piping systems undergo pressure and leak testing
Heating system tested to maintain asphalt temperature at ≤2°C per hour
Computer control system verified for accurate flow adjustment based on speed

Comparison

How It Compares With the Alternatives

4x2 asphalt distributor with 8000 L tank	Lower payload and shorter range but better for tight urban sites and lower maintenance cost
Manual spray distributor	Higher accuracy and consistency but requires more operator attention and crew
Used asphalt truck with no computer control	Higher risk of uneven application and clogging, but lower initial cost

Operating Notes

Use Guide

Confirm the chassis drive configuration and hand of drive before order to match local road rules
Fill the tank only through the designated inlet and avoid overfilling to prevent overflow
Start the heating system at least 30 minutes before spraying to ensure asphalt reaches application temperature
Use the computer control system to match spray rate to vehicle speed for even coverage
Engage the automatic blowing device after each spraying session to clear nozzles and pipes
Drain and rinse the system after use, especially when switching between asphalt types
