High-precision bitumen distributors, modified asphalt plants, decanters, pavers, and compaction units engineered for maximum TCO efficiency.
HEM Group was founded in 1998 by a distinguished group of professors from Chang'an University—China's premier academic institution for highway engineering—and leading experts in the road building industry. Initially operating as Xi'an Hongda Communications Technology Co., Ltd., our organization stands as the earliest high-tech pioneer dedicated to independent research and design of road construction and pavement maintenance machinery in China.
Over more than two decades of technological evolution, we have bridged academic dynamic modeling with heavy-duty field application. Our proprietary patents span critical domains including mechanical dynamics, engine power matching, high-pressure hydraulic transmission systems, and digital electronic micro-control technology. In 2006, the Shaanxi Provincial Department of Science and Technology recognized our commitment to technical rigor by designating HEM Group as an official "High-Tech Enterprise".
To accelerate global infrastructure partnerships, we established HME TOP Machinery Equipment Co., Ltd. in 2017 as our specialized export arm. HME TOP oversees international technical exchanges, global OEM customized manufacturing, cross-border logistics, and multi-regional field engineering support.
Modern road management is shifting from reactive reconstruction to proactive asset preservation, driving demand for intelligent, eco-friendly, and cost-optimized machinery.
Global transportation departments are prioritizing early-stage preventive maintenance—such as chip sealing, slurry sealing, and micro-surfacing—to double pavement lifespans while reducing capital outlay by up to 45% compared to total overlay reconstruction.
Environmental mandates require higher rates of Reclaimed Asphalt Pavement (RAP) utilization. Our Cold In-Place Recyclers pulverize existing distress layers, mix additives on-site, and eliminate binder oxidation while reducing fuel expenditure and carbon footprint.
Modern bitumen distributors and chip sealers feature dynamic computer synchronization. Radar speed sensors match binder spray rates precisely with vehicle ground speed, ensuring uniform binder coverage down to ±1.5% precision across varying road speeds.
From high-speed national expressways to municipal arterial upgrades and heavy-load mining haulage, our equipment portfolio delivers tailored structural solutions.
High-speed milling machines remove damaged asphalt matrices, followed by synchronized chip sealers and high-density SUM series pavers to restore structural load-bearing capacity with minimal traffic disruption.
The DK1800 multifunctional road widener enables rapid paving of narrow road shoulders, trench backfilling, and utility lane expansion without encroaching on main traffic lanes or risking slope instability.
Heavy-duty mobile jaw crushers, mobile primary screens, wheel loaders, and excavators supply raw aggregates and maintain unpaved haul roads in extreme operating environments worldwide.
Our engineering design focuses on solving core equipment pain points: thermal degradation of bitumen, power loss under high load, hydraulic pressure drops, and screed dynamic imbalance.
Our patented DT series bitumen decanting equipment utilizes high-efficiency diesel oil burners combined with closed-loop thermal oil coils, preventing bitumen aging caused by direct flame exposure and yielding rapid container decanting rates.
Incorporating Chang'an University engine-load matching algorithms, our pavers and milling equipment automatically balance hydraulic pump output with engine torque curves, achieving up to 18% fuel savings per operating hour.
HEM OEM modified asphalt plants employ high-shear colloid mills with 5μm dispersion fineness, ensuring complete polymer (SBS/CR) cross-linking to produce high-viscosity asphalt binders suited for extreme climate variation.
We support overseas highway contractors, regional machinery distributors, and municipal buyers with custom modifications, fast spare-parts supply, and multi-lingual commissioning.
HME TOP Machinery handles complete export logistics including customs documentation, multi-modal transport, and regional homologation for over 60 countries and regions worldwide:
