DONGFENG asphalt distribution truck

High-Performance Asphalt Distributor truck for Highway Construction – DONGFENG Model with Advanced Spraying Technology

Engineered for precision and durability, this DONGFENG asphalt distributor truck is a semi-automatic heavy-duty vehicle designed to deliver consistent and uniform application of hot asphalt, modified bitumen, emulsified asphalt, and other paving materials across high-grade road projects. Ideal for permeable oil layers, waterproofing membranes, and adhesive applications in highway construction, the system combines robust engineering with intelligent control technology to ensure optimal performance under diverse environmental conditions.

Featuring a reliable Dongfeng Tianjin DFL1160BX1V chassis compliant with National V emission standards, the truck offers exceptional stability and maneuverability. With an adjustable spreading width ranging from 4.5 to 6 meters and a precise flow rate between 0.2 and 4.0 liters per square meter, it supports flexible operation on both narrow and wide road surfaces. The vehicle operates at speeds from 1.5 to 7 km/h, allowing operators to maintain accuracy while maintaining productivity during large-scale infrastructure work.

The advanced heating system uses an imported Italian Riallo G20 diesel burner capable of delivering 200,000 kcal/hour, ensuring rapid and even temperature control within the asphalt tank—critical for maintaining material viscosity and preventing premature solidification. Equipped with a 10,000-liter capacity tank and a 36-nozzle spray configuration (manual one-control-two), the unit enables efficient coverage over extended distances without compromising uniformity. A computerized control panel ensures stable regulation of pressure, flow, and temperature, minimizing waste and maximizing efficiency—a key factor in modern road-building operations where consistency and safety are paramount.

Key components include a high-viscosity pump (Shanggui QGB950), a hydraulic drive motor from Ningbo Telmus, and a heat transfer oil circulation system for safe and effective thermal management. The integrated hydraulic system, manufactured by Shanxi Elm, provides smooth actuation of all moving parts, including the boom and nozzle assembly. Designed with user-centric features such as a rear-mounted manual control platform, the operator can easily manage spraying functions while standing safely away from active areas.

This asphalt spraying vehicle excels in various real-world environments—from urban highways to rural road networks—where precision, reliability, and compliance with international emissions standards matter most. It’s particularly suited for government-backed road maintenance programs, public works agencies, and private contractors involved in pavement rehabilitation, seal coating, or new road surface preparation. Its modular design allows for easy servicing and adaptability to different job sites, making it a cost-effective long-term investment for professional crews worldwide.

Users report that the intuitive interface reduces training time significantly compared to older models, while the robust build quality ensures minimal downtime even in harsh climates. Many appreciate how the system prevents asphalt clogging through proper pre-heating protocols and post-use cleaning routines, extending component life and reducing operational costs. The ability to adjust spray patterns manually based on site conditions adds versatility often missing in fully automated units.

Common questions about this asphalt distributor truck revolve around maintenance best practices, especially after prolonged use or transportation. Operators should always flush the pump and piping when switching jobs or relocating to avoid blockages caused by hardened asphalt residue. Additionally, it's crucial to verify valve positions before starting each shift and ensure the asphalt reaches 160–180°C prior to spraying. If the vehicle is not used for several days, draining the tank entirely prevents damage from prolonged exposure to extreme temperatures or moisture ingress.

With its blend of cutting-edge technology, ergonomic design, and proven field performance, this DONGFENG Asphalt Distribution Truck stands out as a top choice for professionals seeking a dependable solution for modern road construction needs globally.
