Next-Generation Road Shoulder Pavers, Pavement Widening Solutions, and Precision Hydraulic Highway Engineering Machinery
HEM Group was founded in 1998 by a distinguished panel of professors from Chang'an University—Asia's premier institution for highway engineering, pavement science, and construction machinery research. Originally established as Xi'an Hongda Communications Technology Co., Ltd., the enterprise stands as China's earliest high-tech pioneer focusing on the independent R&D and precision manufacturing of advanced road construction equipment.
Guided by relentless technological research, HEM Group has achieved groundbreaking engineering milestones in mechanical dynamics, engine power matching, hydraulic transmission systems, and digital electronic control technology. Recognized as a official "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, the group subsequently launched its dedicated global export arm, HME TOP Machinery Equipment Co., Ltd. in 2017 to provide turn-key international engineering support, OEM customization, and direct factory supply across 60+ countries.
Across global transport infrastructure networks, the widening of existing highways, rural roads, and municipal corridors has emerged as a high-ROI alternative to full pavement reconstruction. Modern heavy civil engineering contractors face strict budgetary constraints, environmental mandates, and demanding project timelines. In this macro environment, selecting top-tier Road Widener Suppliers and OEM Factories plays a decisive role in achieving operational efficiency and paving precision.
Historically, road shoulder expansion, trench backfilling, and lane widening relied on motor graders, wheel loaders, or manual labor. These legacy approaches suffer from inconsistent material depth, severe aggregate segregation, high asphalt waste, and excessive traffic disruption. Purpose-built road wideners—such as the flagship DK1800 Road Widener / Road Shoulder Paver engineered by HME TOP Machinery—revolutionize shoulder paving by offering pinpoint hydraulic control, variable belt conveyor discharge, and specialized strike-off blades.
Direct placement of hot-mix asphalt (HMA), cold mix, aggregate base, or topsoil directly into the widening trench eliminates overspray and road cleanup labor.
Heavy-duty heat-resistant rubber belt systems allow continuous unloading from standard dump trucks at rates up to 300 tons per hour.
Manufactured under strict ISO9001 and CE quality protocols, ensuring structural durability under heavy aggregate dynamic loading.
Engineering excellence lies at the heart of HME TOP Machinery's road shoulder equipment. Developed in collaboration with Chang'an University's Mechanical Dynamics Laboratory, our road wideners feature heavy-gauge structural steel frames, high-torque hydraulic drive motors, and modular extension strike-off shoes capable of placing materials from 0.5 meters up to 3.0 meters wide in a single pass.
| Technical Parameter | DK1800 Standard Model | DK2500 Heavy-Duty OEM | Engineering Benefit |
|---|---|---|---|
| Paving Width Range | 500 mm – 1,800 mm | 500 mm – 2,500 mm (Extenders) | Flexibility for narrow trenches or wide shoulder expansion. |
| Paving Layer Thickness | -150 mm to +300 mm | -200 mm to +350 mm | Supports deep base fill down to fine surface asphalt overlay. |
| Conveyor Capacity | 200 Tons / Hour | 350 Tons / Hour | Maximized material throughput with zero bottlenecks. |
| Conveyor Belt Width | 400 mm Reinforced Vulcanized Rubber | 500 mm High-Temp Heat Resistant | Handles aggregate, stone dust, cold mix, and hot HMA up to 200°C. |
| Hydraulic Drive System | Variable Displacement Load-Sensing | Proportional Digital Hydraulic Valve Controls | Smooth conveyor speed adjustments matching truck discharge. |
| Slope Adjustment Range | ±15% Hydraulic Tilting | ±20% Dual Hydraulic Actuator | Precise grade matching along superelevated curve shoulders. |
| Mounting Compatibility | Wheel Loaders, Tractors, Graders | Universal Fast-Attach Quick Coupler | Seamless integration with existing jobsite heavy equipment. |
Our OEM manufacturing process incorporates dynamic hydraulic power matching. The conveyor feed rate and strike-off blade extension can be adjusted independently via digital electronic control panels or remote wireless interfaces. This guarantees uniform compaction density, prevents aggregate separation, and reduces pavement seam degradation at the joint between old and new asphalt.
Widening national expressways and regional arteries to accommodate emergency stop lanes and bike paths. Eliminates lane closures on adjacent traffic lanes by operating strictly within the shoulder margin.
Ideal for municipality utility crews laying optic fiber, gas mains, or water pipelines. Rapidly backfills aggregate base layer and places asphalt capping directly into narrow cut trenches with high speed.
Upgrading single-lane agricultural and forestry roads into durable two-lane corridors across South America, Southeast Asia, and Africa. Handles crushed rock, gravel, stabilized soil, and asphalt emulsions.
As a full-chain OEM factory and reliable export supplier, HME TOP Machinery provides an integrated portfolio of paving, milling, recycling, and earthmoving solutions engineered for synergy across multi-stage infrastructure projects:
