Explore our flagship tracked pavers, mixing plants, and multi-functional construction machinery.
Founded in 1998 by esteemed professors from Chang'an University—the premier academic cradle of highway transportation and mechanical engineering in China—HEM Group (originally Xi'an Hongda Communications Technology Co., Ltd.) stands as one of the earliest high-tech enterprises dedicated to the independent R&D and manufacturing of advanced road construction machinery.
For over two decades, our engineering methodology has combined academic rigor with industrial innovation. Certified as a "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our research breakthroughs span mechanical dynamics, multi-engine power matching, electro-hydraulic proportional control systems, and digital paving automation.
In 2017, to serve international EPC contractors and municipal ministries, we established HME TOP Machinery Equipment Co., Ltd. as our dedicated global trade, technical support, and after-sales service division.
Analysis of technological shifts, thermal segregation elimination, and high-density screed engineering.
Modern tracked asphalt pavers have evolved from mechanical link systems to CAN-bus digital control architectures. Dual micro-processors regulate track speed and feed conveyors independently, achieving millimeter-level paving smoothness (IRI < 0.8 mm/m).
Transitioning from liquefied gas to high-output 3-phase AC generator electric screed heating guarantees uniform temperature distribution across working widths up to 12 meters, completely preventing bitumen sticking and cold mat joints.
Equipped with dual tamper bars and heavy-duty eccentric vibration units, Chinese factory-built tracked pavers achieve pre-compaction density exceeding 95%, drastically reducing initial roller pass requirements on highway sub-bases.
In high-capacity road construction, the choice between wheeled and tracked pavers hinges on tractive effort, ground contact pressure, and load stability. Tracked asphalt pavers feature wide rubber track pads with hydraulic tensioning systems that distribute operating weights (ranging from 18 to 32 metric tons) evenly over a broad footprint. This minimizes ground disturbance on soft unbound sub-bases while delivering uninterrupted pushing force when pushing fully loaded tri-axle dump trucks.
As global infrastructure mandates transition toward SMA (Stone Matrix Asphalt) and rubberized polymer-modified bitumen mixes, paving machinery must maintain constant velocity without slippage. China’s manufacturing ecosystem, spearheaded by Chang'an University academic insights, has perfected anti-segregation auger drive geometries. By placing reversible hydraulic motors inside the auger gearbox rather than outer chain drives, material flow beneath the center chain tunnel remains uninterrupted, eliminating longitudinal center-line thermal segregation.

Where Chinese machinery design meets AI-driven telematics and 3D digital levelling systems.
Integrating 3D total stations with multi-channel ultrasonic grade sensors. Eliminates stringlines while guaranteeing millimetric elevation accuracy, automatic crown adjustments, and real-time mat thickness compliance directly synced to BIM models.
Infrared thermal cameras mounted overhead monitor the mat behind the screed in real time. Intelligent edge computing algorithms detect cold spots, alerting the operator or adjusting conveyor speed to maintain optimal thermal homogeneity.
Our latest tracked pavers and batch mixing plants are fully optimized for handling up to 50% Recycled Asphalt Pavement (RAP). Enhanced screed wear-resistant alloys (HARDOX 500 equivalent) combined with customized auger pitch configurations resist abrasion from heavy aggregate recycling, lowering material cost per square meter by up to 30%.
