DONGFENG 15CBM synchronous gravel sealing truck

DONGFENG 15CBM Synchronous Gravel Sealing Truck – Advanced Road Surface Protection Solution

Engineered for superior road maintenance and pavement sealing, the DONGFENG 15CBM synchronous gravel sealing truck is a high-performance highway equipment designed to deliver consistent, durable surface treatments. This vehicle integrates advanced hydraulic, electrical, and thermal systems into one seamless unit, enabling efficient asphalt spraying and aggregate spreading in a single pass. Ideal for road rehabilitation projects, bridge deck waterproofing, and urban infrastructure upgrades, it ensures optimal adhesion between binder and stone through synchronized application technology.

The CLW5180TFCC6 model features a robust DONGFENG automotive chassis with a 260 HP Yuchai engine (Euro 3 compliant), offering reliable power output and fuel efficiency. With an overall size of 9000×2500×3530 mm and a total weight of 10,600 kg, this machine balances maneuverability with substantial capacity—housing 6 cubic meters of hot asphalt and 8 cubic meters of crushed stone in its V-shaped hopper design. Its precise control system allows for adjustable spreading widths up to 3750 mm, making it adaptable to various project requirements from narrow culverts to wide highways.

Key advantages include full hydraulic drive operation, eliminating the need for auxiliary power sources; rapid heating via Riya Road diesel burner with automatic thermal oil circulation; and accurate metering of both asphalt dosage (0.2–3.5 L/m²) and stone distribution (±2% error). The use of high-precision nozzles ensures uniform spray patterns across all lanes, while the insulated tank structure maintains temperature stability within ≤20°C over 8 hours—critical for maintaining asphalt viscosity during extended operations. Additionally, the truck supports multiple asphalt types including SBS-modified, emulsified, and modified emulsion asphalts, enhancing versatility on diverse job sites.

This synchronous sealing machine excels in challenging environments such as steep gradients, tight curves, or confined bridge areas where traditional methods fall short. Thanks to gravity-fed stone delivery without mechanical lifting, construction becomes faster and safer. Automation extends to remote control options and on-site manual override, improving operator comfort and reducing physical strain. The integration of proportional valves from Taiwan and double gear pumps from Tianjin further enhances precision and reliability in real-world conditions.

Common applications span highway maintenance, airport runways, industrial yards, parking lots, and municipal roads requiring long-term durability against weathering, traffic wear, and water infiltration. Whether preparing surfaces for overlays or applying protective layers after crack sealing, this truck delivers professional-grade results with minimal labor input—reducing costs while increasing productivity and quality assurance.

Users consistently report improved work efficiency, reduced material waste, and enhanced bonding strength compared to conventional two-step processes. Many praise the intuitive controls, stable performance under varying temperatures, and low maintenance needs due to well-insulated components and corrosion-resistant stainless steel outer shells. Operators appreciate the flexibility to adjust settings mid-operation, ensuring adaptability to different terrain conditions and surface types.

What makes this vehicle stand out? It combines innovation in heating technology, automation, and structural design to create a truly integrated solution for modern road engineering. Unlike older models that rely on flue-based heating or manual calibration, this truck offers zero-start spraying, constant pressure regulation, and digital feedback loops for consistent output. With built-in diagnostics, easy access to service points, and a proven track record in global infrastructure projects, it represents a smart investment for any fleet seeking long-term value and operational excellence.

For professionals involved in road surfacing, pavement preservation, or civil construction, the DONGFENG 15CBM synchronous gravel sealing truck delivers unmatched performance, ease of use, and return on investment. It’s not just a piece of machinery—it's a complete system engineered to elevate the standard of road maintenance worldwide.
