Heavy-duty paving machinery engineered for superior pavement density, smooth International Roughness Index (IRI), and structural endurance.
HEM Group was founded in 1998 by a distinguished coalition of professors from Chang'an University—Asia's premier institution for highway engineering research—and seasoned experts in the road building industry. Originally established as Xi'an Hongda Communications Technology Co., Ltd., HEM Group represents China’s earliest high-tech enterprise dedicated to independent research, digital control integration, and mechanical engineering of road construction equipment.
Since inception, we have aligned our product lifecycle with high-tech research and development, striving to build a globally recognized brand for Chinese construction machinery. Our continuous breakthrough research spans mechanical dynamics, engine power matching, hydraulic closed-loop transmission, and digital electronic control systems, resulting in dozens of national invention patents and provincial technological awards. In 2006, HEM was officially recognized as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology.
In 2017, to expand global direct engineering partnerships, we launched our international sales arm, HME TOP Machinery Equipment Co., Ltd., managing export trade, technical field support, and international cross-border engineering consultancies.
Delivering uncompromised structural integrity, precision machining, and rapid production cycles through digitized factory infrastructure.
Our modern manufacturing facility spans over 50,000 m² of specialized workshops equipped with robotic laser welding, CNC boring mills, and automated shot-blasting paint lines for corrosion protection.
Every paver, milling machine, and bitumen tank undergoes rigorous multi-stage non-destructive testing (NDT), hydraulic high-pressure testing, and field simulation prior to international dispatch.
By producing critical structural assemblies, electronic control harnesses, and hydraulic manifolds in-house, we eliminate third-party markup and insulate clients from global supply chain disruptions.




Tailored heavy machinery suites engineered for diverse operating environments—from highway construction to mining and environmental restoration.
Complete product chain covering asphalt mixing plants, high-density pavers, intelligent bitumen distributors, synchronous chip sealers, slurry sealers, and road wideners to guarantee low pavement roughness (IRI) and extended operational fatigue life.
Heavy-duty wheel loaders, hydraulic excavators, backhoe loaders, and heavy bulldozers designed for deep subgrade compaction, drainage excavation, bridge foundation work, and rapid site clearance across commercial and residential developments.
Mobile jaw crushers, mobile primary vibrating screens, and heavy-duty screening plants delivering high-tonnage aggregate classification directly at quarry faces, drastically cutting haulage logistics and aggregate preparation costs.
Driving digital transformation in asphalt paving through automation, intelligent sensors, and sustainable cold recycling solutions.
Modern infrastructure contracts demand millimeter-level accuracy. HEM Group's technological roadmap integrates 3D GNSS satellite positioning and total station tracking directly with proportional electro-hydraulic screed controls. This eliminates manual stringline setup, minimizes asphalt over-allocation, and guarantees pre-set cross-slope precision.
Preventing thermal segregation is vital for asphalt durability. Our next-generation SUM series pavers and rollers feature integrated infrared thermal mapping systems combined with accelerometer-based stiffness measurement. Operators receive real-time color-coded feedback showing mat temperatures and compaction passes, eliminating cold spots and over-compaction breakdown.
Sustainable roadway rehabilitation requires minimizing reclaimed asphalt pavement (RAP) waste. Our OEM CIPR equipment pulverizes damaged asphalt layers, mixes them with cement or bituthene emulsion in-situ, and lays down a rehabilitated base layer in a single continuous pass. This process reduces aggregate haulage emissions by up to 75% while cutting material procurement overhead.
All HME TOP heavy machinery comes equipped with CAN-bus telematics gateway modules. Fleet managers can remotely monitor engine torque curve utilization, hydraulic oil viscosity indicators, fuel burn rates, and geofence operational parameters in real-time, drastically reducing unexpected jobsite downtime.
Technical Innovation Focus: Modern asphalt paving is moving away from purely mechanical adjustments toward closed-loop electro-hydraulic automation. By integrating Chang'an University's proprietary power-matching algorithms, HEM equipment achieves up to 14% lower fuel consumption per ton of placed asphalt compared to traditional mechanical-drive machinery.

In-depth technical clarifications for equipment managers, highway engineers, and procurement directors.
Selection depends on the structural pavement design. Asphalt pavers (such as our SUM Series) lay down flexible bituminous mixtures requiring thermal compaction and dynamic screed heating. Slip-form concrete pavers are used for rigid pavements, extruding low-slump hydraulic concrete for heavy-duty airport aprons, highway barriers, and channel linings. HEM offers both flexible asphalt paving lines and multi-functional slip-form pavers customized for your project specifications.
CIPR eliminates the cost of milling, trucking, and disposing of old asphalt materials while cutting virgin aggregate purchasing expenses. By pulverizing and rejuvenating damaged pavement layers directly on site, project timelines are reduced by up to 50%, fuel consumption drops significantly, and overall pavement rehabilitation cost per square meter decreases by 30% to 45%.
Our intelligent bitumen distributors utilize closed-loop radar ground speed matching paired with computer-controlled proportional hydraulic pumps. As truck speed varies, the system automatically adjusts spray bar pump pressure and valve opening timing, keeping the application rate within an ultra-precise ±1.5% margin regardless of vehicle speed fluctuations.
We supply a mandatory 1-to-2-year wear parts package with initial equipment shipments. Furthermore, our localized service depots across Africa, Southeast Asia, and Eurasia maintain stock of hydraulic pumps, electronic sensors, cutter bits, and wear plates. We offer 24-hour remote video troubleshooting and can dispatch field engineers for on-site commissioning and repair.
