Explore our primary industrial flagships engineered for extreme durability, precise material distribution, and maximized project yield across global highway and municipal developments.
Founded in 1998 under the academic leadership of distinguished professors from Chang'an University—China's premier institution for highway engineering technology—HEM Group (originally Xi'an Hongda Communications Technology Co., Ltd.) stands as one of the earliest high-tech pioneers dedicated to the independent research, thermodynamic engineering, and mechanical optimization of heavy road building machinery.
Our core engineering philosophy fuses deep mechanical dynamics with real-world pavement science. Over twenty-five years of dedicated R&D have yielded groundbreaking invention patents across engine power matching, hydraulic transmission stability, micro-computerized screed leveling, and digital electronic control systems. Officially recognized as a "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, HEM Group established its specialized global commercial arm, HME TOP Machinery Equipment Co., Ltd., in 2017 to streamline international technical exchanges, global logistics, OEM customization, and end-to-end field support.





Global transport infrastructure investments demand unprecedented paving precision, thermal efficiency, and minimal lifecycle operation costs (TCO). Modern road building projects—ranging from multi-lane interprovincial expressways in Southeast Asia to heavy-haul corridor maintenance in Sub-Saharan Africa and mining haulage roads in South America—face dual challenges: accelerating delivery schedules while meeting rigorous smoothness (IRI - International Roughness Index) standards.
Preventing thermal segregation is crucial to eliminating premature road cracking. Our advanced SUM Series asphalt pavers utilize continuous electric and gas-heated heavy-duty screeds with pulse-width modulation (PWM) heating zones to ensure uninterrupted aggregate mat temperature.
Achieving high initial mat density prior to roller compaction reduces mat displacement and preserves surface micro-texture. Dual-tamper bar technology offers dynamic frequency adjustment up to 1,800 rpm for thick lift asphalt paving.
Minimizing virgin aggregate extraction and reducing asphalt plant carbon output, our CIPR trains pulverize distressed pavement, mix bitumen emulsion on-site, and re-lay structural base layers in a single energy-efficient pass.
From heavy earthmoving and primary quarrying to precision asphalt laying and municipal shoulder expansion, our machinery portfolio delivers full lifecycle support across five primary application domains:
Deploying SUM Series Asphalt Pavers alongside Paver Feeders and Intelligent Bitumen Distributors guarantees continuous material supply, eliminating thermal joint discontinuities across multi-lane arterial roads.
DHP Series Slip-Form Cement Pavers handle heavy hydraulic concrete slip-forming for high-speed expressways, airport runways, and agricultural water channels with micro-meter grade elevation control.
The DK1800 Road Widener precisely dispenses gravel, soil, or asphalt to extend existing shoulders without disrupting main traffic flows, reducing crew size and operational hazard.
Self-Propelled Chip Spreaders and Synchronized Chip Sealers bind aggregate and hot modified bitumen simultaneously, sealing micro-fissures and extending pavement life cycle by up to 8 years.
Mobile Jaw Crushers, Vibrating Screen Plants, Backhoe Loaders, and Mini Excavators deliver complete site preparation, aggregate production, and construction demolition recycling.

HEM Group’s forward R&D engineering roadmap combines machine learning algorithms, zero-emission electro-hydraulic powertrains, and stringless 3D leveling integration to redefine future road building standards:
Integrating 3D GNSS positioning with robotic total stations to eliminate traditional mechanical grade wires, cutting setup times by 70% while achieving sub-millimeter elevation accuracy.
Non-destructive microwave sensors embedded beneath screed plates provide real-time compaction feedback directly to operators, eliminating cold spots and density voids.
Replacing traditional auxiliary hydraulic circuits with high-efficiency permanent magnet electric motors to cut fuel consumption by up to 25% and reduce engine noise in urban zones.
Cloud-based diagnostic tracking monitors hydraulic oil cleanliness, screed wear rates, fuel burn, and GPS location in real time, supporting proactive maintenance worldwide.
Our dedicated global export arm, HME TOP Machinery Equipment Co., Ltd., manages international sales logistics, customs documentation, regional compliance (ISO9001, CE, Euro Stage V/EPA emissions), and on-site engineering training.
End-to-end containerized, Flat-Rack, and Ro-Ro shipping solutions with complete export documentation ensuring seamless port entry across Africa, South America, and Central Asia.
Field engineers dispatched directly for site setup, calibration, screed alignment, and local mechanic training supported by localized regional service hubs.
Direct access to genuine replacement parts—hydraulic pumps, tamper bars, conveyor chains, wear plates—delivered at factory-direct pricing to minimize operational downtime.
Our machinery and technical teams operate in over 60 countries and regions worldwide, including Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, Sri Lanka, India, Nigeria, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, and beyond.







Detailed engineering answers to common technical queries from general contractors, municipal authorities, and equipment importers.
Asphalt pavers deploy hot bituminous mixtures using heated floating screeds and tamper bars to achieve preliminary compaction before roller rolling. In contrast, Slip-Form Cement Concrete Pavers (such as our DHP Series) pour heavy, low-slump hydraulic concrete into continuous structural forms without fixed molds, utilizing internal high-frequency vibrators to consolidate rigid pavements, highway barriers, or water drainage canals.
Our SUM Series asphalt pavers utilize continuous dual-speed auger distribution coupled with multi-zone screed heating systems (electric or LPG). By pairing our pavers with specialized Paver Feeders, contractors eliminate mechanical truck bumps and maintain uniform thermal mass, resulting in optimal International Roughness Index (IRI) scores.
Yes. The DK1800 Road Widener handles hot asphalt mix, crushed aggregate base, soil cement, and topsoil. Featuring hydraulic conveyor speed modulation and adjustable side-discharge strike-off blades, it smoothly places material up to target width specifications in a single operation.
We provide tailor-made machine adaptations including engine emissions configuration (Euro Stage III / Tier 4 Final / Stage V), customized screed extension widths, tropicalized cooling radiators for high-ambient climates, specialized track shoes, and branded paint schemes.
Through HME TOP Machinery Co., Ltd., we maintain regional spare parts inventories and local technical teams in key international markets (including Russia, South Africa, Malaysia, and Uzbekistan). We offer 24-hour remote video diagnostics and can dispatch qualified service engineers for on-site commissioning and operator training.
