SHACMAN synchronous gravel sealing truck

SHACMAN Synchronous Gravel Sealing Truck – Advanced Road Maintenance Solution for Global Infrastructure Projects

Engineered for precision, durability, and efficiency, the SHACMAN synchronous gravel sealing truck is a high-performance road maintenance vehicle designed to deliver superior surface protection across diverse climates and terrains. This comprehensive system integrates asphalt distribution, stone spreading, and intelligent control mechanisms into one seamless operation—ideal for highway rehabilitation, rural road surfacing, and urban pavement enhancement projects worldwide.

At its core, this machine combines robust automotive engineering with cutting-edge fluid dynamics and automation technology. The chassis features a 5300mm wheelbase, a powerful CA4DK1-22E6 engine (220 horsepower), and a durable stainless steel tank structure with 50mm rock wool insulation to maintain optimal asphalt temperature during transport. With an asphalt tank capacity of 6 cubic meters and a stone hopper volume of 8 cubic meters, it ensures consistent material flow for extended work periods without frequent refills.

Key performance characteristics include a double gear pump system (model 05-130-BD31), a proportional valve (EFRD-G03-160-5-31) from Taiwan for accurate flow regulation, and a fully hydraulic drive mechanism that enables smooth, responsive operation on uneven surfaces. The onboard computerized control panel offers real-time monitoring via touch-screen interface, while integrated video surveillance enhances operator visibility and safety. Additionally, the inclusion of an angle meter allows precise adjustment of the material discharge gate, improving accuracy in curving or confined areas such as bridges, culverts, and tight bends.

The truck’s synchronized application process involves simultaneous spraying of hot asphalt (ranging from 0.3–4.0 liters per square meter) followed by uniform stone dispersion at a spacing of 125mm over a working width of up to 4 meters. This method ensures immediate bonding between aggregate and binder, forming a durable, skid-resistant surface layer. Compatible with various asphalt types—including SBS-modified, emulsified, and rubber-modified formulations—the system supports flexible use depending on local climatic conditions and project specifications.

Designed for global deployment, this equipment excels in both large-scale highway resurfacing and localized infrastructure upgrades. Whether used in arid regions requiring long-lasting surface protection or temperate zones where seasonal maintenance is critical, the SHACMAN gravel sealer adapts effortlessly. Its automated heating system, powered by a diesel burner and thermal oil circulation, guarantees stable temperatures even in cold environments, making it suitable for year-round operations in Europe, North America, Australia, and beyond.

Users consistently praise the machine's reliability, ease of operation, and minimal downtime. Operators appreciate the intuitive cab controls, which reduce training time and enhance productivity. The internal lifting hopper design simplifies stone loading and distribution, particularly beneficial for complex construction sites like bridge decks or narrow access roads. Moreover, the modular setup allows quick switching between different materials and configurations based on job requirements.

Common inquiries often revolve around operational flexibility, maintenance intervals, and compatibility with different aggregate sizes. The unit performs optimally with stones sized between 5–20mm, ensuring proper embedment and surface texture. Routine servicing includes checking the hydraulic lines, inspecting the spray nozzles for clogs, and verifying the integrity of the insulation layer to prevent heat loss. Most models require service every 500 operating hours under normal conditions, though this may vary based on usage intensity and environmental factors.

For contractors seeking a versatile, efficient, and future-ready solution for modern road maintenance needs, the SHACMAN synchronous gravel sealing truck stands out as a globally trusted choice—combining proven engineering with smart automation to elevate pavement quality standards worldwide.
