Direct-from-factory high-performance surface treatment systems and infrastructure engineering solutions
Combining academic research from Chang'an University with industrial-scale machinery production since 1998
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—HEM Group represents the pinnacle of technological integration in heavy road machinery. Recognizing early on that global road networks required preventative maintenance rather than costly reconstruction, our founding team dedicated decades to researching mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems.
In 2006, our commitment to technological breakthroughs earned official recognition as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology. Today, this R&D heritage translates into ultra-precise slurry seal pavers and micro-surfacing machinery capable of operating under extreme ambient conditions worldwide.
To streamline global commercial partnerships, our dedicated international trade entity, HME TOP Machinery Equipment Co., Ltd. (established 2017), manages global technical exchanges, export clearance, and on-site field engineering. Operating out of a modernized 5,000+ M² production hub, our facility maintains an annual output capacity exceeding 5,000 sets of equipment and auxiliary units.
With an active export footprint encompassing over 60 countries across Africa, Southeast Asia, Central Asia, Eastern Europe, and South America, HEM Group provides a seamless end-to-end supply chain. From raw aggregate screening to advanced polymer-modified emulsion distribution, our heavy machinery ensures optimal skid resistance and waterproofing for critical transportation corridors.
White-paper analysis: Paradigm shift toward sustainable cold-mix preservation & lifecycle optimization
The global road maintenance sector is undergoing an unprecedented structural transition. Municipal authorities, state highway departments, and private concessionaires are pivoting away from energy-intensive hot-mix asphalt (HMA) overlays toward cold-applied preventative treatments. Among these, Pavement Slurry Seal and Micro-Surfacing have emerged as the gold standards for extending pavement structural life while minimizing carbon emissions.
Slurry seal applications operate at ambient temperatures, eliminating thermal heating energy. This yields an 80% reduction in greenhouse gas emissions per square meter compared to conventional hot asphalt applications.
Engineered polymer-modified quick-set emulsions allow micro-surfacing layers to cure rapidly, enabling full traffic restoration within 1 hour of application—critical for high-density arterial routes and urban expressways.
Frictional micro-texture degradation is a leading cause of wet-weather skidding accidents. Slurry seal seals micro-fissures, prevents water ingress, and restores surface friction coefficients to international safety benchmarks.
