Explore our OEM direct-factory flagship equipment deployed in over 60 countries for highway, municipal, and industrial construction.
Founded in 1998 as Xi'an Hongda Communications Technology Co., Ltd. by a distinguished cohort of professors from Chang'an University—China's premier institution for highway engineering and transportation machinery—HEM Group stands at the forefront of road surface paving technology. Decades of rigorous theoretical research merged with practical field testing have allowed us to pioneer high-tech breakthroughs across mechanical dynamics, engine power matching, high-pressure hydraulic transmission, and digital electronic control systems.
Recognized as an official "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our organization transitioned into full-scale global operations with the launch of HME TOP Machinery Equipment Co., Ltd. in 2017. This dedicated international export arm streamlines global technical exchanges, custom OEM project engineering, export logistics, and worldwide customer support.
Today, HEM Group delivers a vertically integrated ecosystem for road paving and infrastructure preservation, operating state-of-the-art facilities equipped with advanced CNC laser cutting, automated robot welding, and environmental testing bays.
Macroeconomic shifts, environmental mandates, and demanding civil engineering standards are radically redefining modern road paving technology.
Global road authorities are prioritizing Cold In-Place Recycling (CIPR), warm-mix asphalt (WMA) technologies, and reclaimed asphalt pavement (RAP) integration. Modern pavers and recyclers must maintain thermal homogeneity while reducing hydrocarbon fumes and diesel consumption.
To prevent structural pavement fatigue, infrastructure budgets have shifted from reactive reconstruction to proactive maintenance. Synchronized chip sealers—which spray binder and aggregate simultaneously within milliseconds—ensure maximum bond strength and eliminate aggregate stripping.
High-speed highway construction demands laser levelling, ultrasonic material feed sensors, and intelligent heating screeds. Automated grade control minimizes human error, guaranteeing uniform thickness and smooth rideability metrics (IRI compliant).
International contractors and government procurement directors evaluate machinery suppliers based on Total Cost of Ownership (TCO), hydraulic reliability, modular component sourcing, and localized technical adaptation. Below is a comparative breakdown of off-the-shelf equipment versus HEM Group's OEM tailored paving solutions:
| Procurement Parameter | Generic Market Suppliers | HEM Group OEM Solutions |
|---|---|---|
| Hydraulic System Engineering | Fixed-displacement pumps, prone to overheating in tropical ambient conditions. | Variable-displacement proportional hydraulics with high-efficiency oil cooling systems. |
| Bitumen Spraying Accuracy | Manual valve controls with ±8-12% flow deviation. | Computer-controlled automatic dosage with real-time speed compensation (error < ±1%). |
| Chassis & Axle Customization | Standard commercial chassis with limited axle load modification. | Reinforced heavy-duty chassis customized to regional road legal limits and harsh terrain. |
| Component Interchangeability | Proprietary closed-source parts leading to high replacement costs. | Global brand strategic sourcing (Danfoss, Rexroth, Cummins) ensuring local part availability. |
| After-Sales & Field Support | 3rd-party regional agents with limited technical depth. | Direct factory technicians, 24/7 telematics support, and regional hubs in 8 key countries. |
From heavy highway construction to specialized urban maintenance, eco-restoration, and mining site earthmoving.
High-capacity asphalt mixing plants coupled with precision asphalt pavers and paver feeders ensure uninterrupted paving workflow. Integrated heating systems keep asphalt binders at optimal compaction temperatures, delivering crack-resistant, heavy-duty asphalt layers capable of withstanding extreme axle loads.
Our slurry seal pavers and synchronized chip sealers provide cost-effective life extension for aging pavement infrastructure. By applying ultra-thin polymer-modified bitumen layers, municipalities restore surface friction and seal micro-fissures before structural breakdown occurs.
HEM Group’s R&D vision integrates artificial intelligence, telematics, and clean energy to redefine future construction sites.
Next-generation intelligent bitumen distributors and asphalt pavers utilize real-time infrared thermal profiling. System algorithms automatically adjust screed tamper speed and spray pressure to prevent thermal segregation during laydown.
Integrated cloud diagnostic platforms monitor hydraulic pressure, engine load factors, binder spray volume, and maintenance cycles in real time. Remote diagnostic modules allow factory engineers to assist field operators anywhere on earth.
Addressing strict municipal noise and emissions requirements, HEM Group is actively testing zero-emission mini excavators, electric steel drum rollers, and low-noise electric asphalt heating systems for urban night works.
Navigating international infrastructure projects requires full adherence to strict local regulations and emissions standards. All HEM Group machinery complies with ISO9001 quality management benchmarks, CE certification for European markets, and EPA Tier 4 / Stage V engine emissions standards.
To minimize project downtime, we have established direct technical service centers and spare parts distribution depots across strategic international markets:
