Factory-direct engineering excellence designed for maximum performance, minimal downtime, and precision binder application.
Pioneering bitumen dynamics and heavy engineering since 1998, backed by prestigious university research and patented innovations.
In the contemporary landscape of civil infrastructure, the shift from reactive structural rehabilitation to proactive asset preservation represents the most critical strategic evolution for highway authorities, municipal engineering departments, and international concessionaires. As global highway networks mature, maintaining asset structural integrity while optimizing Life Cycle Cost Analysis (LCCA) requires specialized, high-precision equipment designed explicitly for bituminous surface treatments, cold recycling, and micro-surfacing applications.
HEM Group (originally established as Xi'an Hongda Communications Technology Co., Ltd. in 1998) was co-founded by leading academic professors from Chang'an University—China's premier institution for highway engineering, mechanical dynamics, and pavement material science. As one of the earliest high-tech enterprises dedicated to independent R&D of road construction equipment in China, HEM Group bridges advanced theoretical dynamics with rugged industrial manufacturing.
E-E-A-T Benchmark: Certified as a National "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our engineering roster holds groundbreaking patents in mechanical dynamics, engine power matching, high-pressure hydraulic transmission, and digital CAN-bus electronic control systems.
Analyzing macroeconomic procurement requirements across North America, Europe, Asia-Pacific, Latin America, and Africa.
Governments worldwide are shifting capital allocations from high-cost structural reconstruction to cost-effective preventive surface treatments (Chip Sealing, Slurry Sealing, Micro-surfacing), extending pavement service life by 7 to 10 years at one-fourth the cost.
International contractors demand machinery featuring reduced greenhouse emissions, intelligent emulsion heating management, and Cold In-Place Recycling (CIPR) capabilities that reduce aggregate mining demands and cut VOC emissions significantly.
Modern road authorities require real-time metering accuracy within ±1% for binder distribution and aggregate spreading. Computerized radar controls, automatic spray bar expansion, and remote IoT diagnostics have become compulsory tender specifications.

From mineral aggregate processing to intelligent road surface finishing: Our one-stop heavy equipment line.
Our complete machinery supply chain spans three distinct construction sectors:








End-to-end OEM customization, overseas service hubs, and direct factory technical support.
Custom structural design, tank capacity scaling, burner brand integration (Riello, Baltur), and chassis matching (Dongfeng, Sinotruk, FAW, MAN, Volvo, Mercedes-Benz compatibility).
Our engineering team provides comprehensive guidance on binder formulation, aggregate gradations, emulsion viscosity compliance (ASTM D244/ISSA standards), and field execution.
Dedicated technical support centers and spare parts stocking warehouses across Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka to eliminate downtime.








Integrating artificial intelligence, smart sensor arrays, and zero-emission drives into road maintenance platforms.
The future of road preservation lies in real-time surface diagnostic integration. HEM Group is actively developing smart preservation fleets equipped with 3D LiDAR surface profiling, automated crack-detection vision sensors, and dynamic spray control systems. By adjusting bitumen emulsion delivery rates dynamically based on sub-millimeter surface void measurements, our next-generation machinery minimizes material waste while ensuring optimal binder film thickness.
Furthermore, our engineering teams are pioneering hybrid and electric-powered compaction and milling systems, dramatically reducing fuel consumption on urban highway maintenance jobs while ensuring strict compliance with European Tier 5 and North American Tier 4 Final emission regulations.
