Explore our engineering-grade road building machinery designed for high-accuracy cement spreading, subgrade stabilization, and heavy-duty pavement rehabilitation across global infrastructure projects.
Modern highway construction and pavement rehabilitation demand strict engineering tolerances to guarantee subgrade load-bearing capacities (Unconfined Compressive Strength / UCS) and long-term structural integrity. In modern subgrade engineering, Full-Depth Reclamation (FDR) and cement-bound base courses have superseded traditional crushed stone layers due to superior fatigue resistance and economic efficiency. As a leading China Cement Spreader Manufacturer & Supplier, HEM Group (HME TOP Machinery Equipment Co., Ltd.) delivers field-proven volumetric cement distribution systems engineered to eliminate binder variance across diverse geoclimatic zones.
In low-bearing subgrades, incorrect binder ratios cause severe structural failure modes: under-dosing leads to micro-cracking and insufficient California Bearing Ratio (CBR) values, while over-dosing causes brittle fatigue failure and unacceptable material costs. Specialized truck-mounted volumetric cement spreaders, such as the flagship DGL5250TFS-166 Cement Spreader, address these operational bottlenecks through closed-loop micro-computer metering valves synced directly with ground travel velocity.
According to global transport infrastructure standards (including AASHTO and Eurocode norms), uniform binder distribution reduces overall cement consumption by up to 14% compared to manual or bulk-unloading methods while increasing daily paving speed by over 300%. Our factory direct solutions provide global EPC contractors with the precise operational control required for heavy-haul mining roads, high-speed expressways, and airport sub-base preparations.
HEM Group’s machinery development is backed by deep R&D roots established by Chang'an University highway machinery professors in 1998. The technology roadmap of our cement spreading equipment focuses on three major pillars: Volumetric Dosing Accuracy, Dynamic Radar Travel Speed Synchronization, and Pneumatic Eco-Dust Suppression.
Utilizes multi-compartment rotary discharge valves coupled with high-torque hydraulic motors. Integrated load cells continually monitor mass-flow variations to deliver accurate cement, lime, or fly-ash coverage regardless of aggregate roughness.
Ground-pointing non-contact Doppler radar sensors feed real-time travel velocity to the central ECU. If truck speed shifts due to incline or terrain variation, the hydraulic valve automatically adjusts feeder rotation speed to maintain uniform kg/m² delivery.
Heavy-duty flexible rubber curtains paired with optional negative-pressure dust extraction canvas hoods retain ultra-fine binder particles within the spreading zone, protecting working crews and meeting strict urban environmental guidelines.

HEM Group was founded in 1998 by professors from Chang'an University—China's premier institution for highway engineering research—and industry specialists, originally under the name Xi'an Hongda Communications Technology Co., Ltd. We represent the earliest high-tech enterprise dedicated to independent design and manufacturing of advanced road construction and maintenance machinery in China.
In 2006, Shaanxi Provincial Department of Science and Technology recognized us as a official High-tech Enterprise following a series of patents in mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems. To accelerate global technical exchanges, our dedicated export corporation, HME TOP Machinery Equipment Co., Ltd., was established in 2017 to handle global trade, customized OEM manufacturing, and direct technical field support.
Founded by Chang'an University professors, embedding scientific mechanical dynamics and hydraulic research directly into heavy road equipment production.
Operating a modernized production base producing over 5,000 units annually with strict ISO9001 quality audits and international CE compliance.
Exporting to more than 60 countries across Asia, Africa, Eastern Europe, Latin America, and Oceania with active service hubs worldwide.
As an established B2B China Cement Spreader Supplier, our machines are customized to withstand harsh operating conditions across diverse global climates—from the high-temperature humidity of Southeast Asia to freezing sub-zero environments in Central Asia and Russia.
In full-depth reclamation (FDR) projects across Eastern Europe and Latin America, our cement spreaders work directly ahead of cold recyclers, precisely distributing 15-35 kg/m² cement dosages onto pulverized asphalt pavement before water injection and soil blending.
For open-pit mining routes in Africa and Australia carrying 100-ton dump trucks, subgrades require lime and cement stabilization up to 400mm deep. Our DGL series delivers high binder mass per pass, preventing mud pumping and subgrade rutting under extreme axle loads.
Commercial airfield sub-bases demand strict flatness and CBR uniformity. The computer-controlled micro-metering system ensures zero aggregate streaks or binder void spots, guaranteeing consistent load distribution under dynamic aircraft landings.
HEM Group equipment has been deployed across projects in India, Sri Lanka, Indonesia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, Russia, Malaysia, Uzbekistan, Ghana, Kenya, and beyond.
HEM Group provides complete machinery suites for entire pavement construction workflows: from initial aggregate crushing to subgrade stabilization, asphalt paving, slurry sealing, and ongoing road maintenance.

Our DGL5250TFS-166 and related spreaders use a non-contact ground Doppler radar that continually calculates real-time ground speed. The central micro-computer processes this velocity data and dynamically adjusts the hydraulic motor speed driving the rotary volumetric feeder valve, maintaining accurate spread density (kg/m²) regardless of truck speed fluctuations.
In addition to standard Portland cement, our spreaders are engineered to handle hydrated lime, quicklime powder, fly ash, ground granulated blast-furnace slag (GGBS), and specialized soil-stabilizing chemical powders without clogging or bridge formation inside the hopper.
Our spreaders are fitted with heavy industrial rubber skirt curtains surrounding the discharge area. Furthermore, an optional closed-loop negative-pressure canvas hood system compresses airborne dust down into the soil bed, protecting surrounding traffic and ensuring strict environmental compliance.
Yes. The spreading bar features pneumatic multi-segment gate controls (e.g., 28 independent discharge gates on the 2,500mm bar). Operators can activate or deactivate individual gates directly from the cab touch screen to match lane width or avoid obstacles without stopping the vehicle.
We offer turnkey factory-integrated models mounted on heavy-duty Sinotruk, Shacman, or Dongfeng chassis with engine configurations compliant with Euro 3, Euro 5, or Tier 4 Final / Stage V emission regulations. Alternatively, we can supply upper-structure spreader modules custom-tailored to mount onto customer-supplied local chassis (e.g., Mercedes-Benz, MAN, Volvo, ISUZU).
Standard model production lead time is 15–25 business days. Heavy equipment is shipped via RORO (Roll-on/Roll-off) vessels, Flat Rack containers, or Breakbulk shipping depending on destination port capabilities, fully treated with marine anti-corrosion wax coatings.
