High-precision asphalt mixing batching plants, pavers, chip sealers, and road rehabilitation equipment built for global contractors.
Established in 1998 as Xi'an Hongda Communications Technology Co., Ltd., HEM Group was founded by a distinguished body of professors from Chang'an University—China’s premier institution for highway transportation and mechanical engineering research. This academic backbone established HEM Group as one of the earliest high-tech pioneers in China dedicated to the independent research, thermodynamic modeling, and structural engineering of modern road construction equipment. Over twenty-six years of continuous operational evolution, our engineering teams have bridged theoretical mechanical dynamics with real-world pavement engineering.
Our research trajectories focus heavily on high-end road maintenance machinery, yielding dozens of breakthrough patents in engine power matching under heavy thermal loads, closed-loop hydraulic transmission efficiency, multi-stage aggregate screening dynamics, and digital micro-computer batch control systems. Recognized in 2006 as a state-level "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology, HEM Group evolved its international outreach in 2017 with the formation of HME TOP Machinery Equipment Co., Ltd.—our dedicated international sales, technical support, and global OEM export hub.
The global asphalt manufacturing landscape is undergoing a systemic paradigm shift driven by stringent municipal emission regulations, volatile crude oil prices, and the global mandate for Net-Zero infrastructure projects. Contractual specifications across North America, the European Union, Southeast Asia, and the Middle East now demand asphalt mixing plants capable of reducing carbon footprints without compromising mix stability or fatigue life.
Modern plants utilize direct warm-mix chemical foaming systems to lower production temperatures by 20°C to 40°C, reducing fuel consumption by up to 30% and significantly decreasing greenhouse gas emissions during mixing and laydown operations.
Reclaimed Asphalt Pavement (RAP) technology is no longer optional. Advanced OEM plants integrate dual-drum counter-flow systems and recycling rings, permitting up to 50%–60% RAP addition without causing bitumen thermal degradation or binder oxidation.
Integrating cloud-linked PLC architectures allows real-time aggregate moisture compensation, remote thermal diagnostics, batch weighing accuracy within ±0.5%, and automated material usage tracking directly into ERP enterprise systems.
As an original equipment manufacturer (OEM), HME TOP Machinery provides end-to-end capital equipment ecosystems designed to work in seamless mechanical synchrony. From initial raw aggregate processing to final surface compaction, our product portfolio addresses every phase of highway infrastructure development.
An asphalt mixing plant is only as effective as the downstream machinery laying and sealing the material. HME TOP Machinery designs its modular asphalt batch plants alongside matching SUM-series pavers, intelligent bitumen distributors, and synchronized chip sealers to guarantee thermal consistency and ideal layer bonding.
Evaluating OEM asphalt mixing plants requires a holistic Total Cost of Ownership (TCO) evaluation framework balance between initial capital outlay and long-term operating costs.
Fuel accounts for up to 50% of direct operational costs in asphalt production. HME TOP plants utilize heat-exchanger flight designs inside drying drums, reducing energy loss and lowering fuel burn to under 6.5 kg per ton of asphalt produced.
Our plants feature containerized modular sub-assemblies. Pre-wired plug-and-play wiring looms minimize field assembly time from weeks to days, drastically reducing civil works and on-site engineering labor expenditures.
Mixer arms, paddle tips, and bin liners are cast from high-chromium alloy steel (HB ≥ 500), extending component lifespan even when processing highly abrasive quartzite or crushed granite aggregates.
Operating heavy construction equipment globally requires comprehensive local support, regulatory compliance, and robust spare parts availability. HME TOP Machinery has established regional sales offices, technical distribution centers, and spare parts depots strategically positioned across critical markets including Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka.
All HME TOP asphalt batching plants, pavers, and crushing machinery are manufactured under ISO 9001:2015 Quality Management Systems and hold full CE marking compliance alongside EAC certification for Eurasian Economic Union territories.
We deploy factory-certified field technicians directly to client work sites worldwide. Services include foundation planning, mechanical erection, electrical commissioning, burner calibration, and operator training to guarantee optimal performance.
HME TOP Machinery’s R&D department, in partnership with Chang'an University highway research centers, is currently pioneering next-generation technological advancements tailored for intelligent, sustainable road construction:
Developing zero-carbon burner combustion systems capable of firing cleanly on pure hydrogen gas or hydrogen-natural gas blends, eliminating thermal combustion CO2 emissions entirely.
Deploying vibration analysis sensors and thermal imaging across mixer gearboxes, elevator chains, and exhaust fans to detect mechanical wear before catastrophic failures occur.
Integrating telemetry between asphalt mixing plant discharge gates, haul truck GPS fleets, and paver feed hoppers to optimize delivery schedules and maintain continuous paver speed without stopping.
Expert answers regarding custom OEM manufacturing, plant selection, installation, and maintenance.
Batch mixing plants screen hot aggregates into separate bin compartments before precisely weighing each fraction, aggregate, filler, and bitumen per individual mix batch. This guarantees maximum mix precision, ideal for high-specification highways and airport projects. Continuous drum plants mix aggregate and bitumen continuously inside the drum, offering lower initial capital cost but less flexibility when switching mix formulas frequently.
Our engineering team customizes plants to meet local environmental, electrical, and fuel standards. Custom options include selecting burner fuel configurations (diesel, heavy oil, natural gas, LPG), custom baghouse filtration sizing for environmental zones, voltage/frequency motor matching (e.g., 380V/50Hz vs. 460V/60Hz), and extreme weather insulation packages for Siberian freezing or Middle Eastern heat.
Standard HME TOP asphalt batch plants can incorporate up to 25% cold RAP directly into the mixer. When retrofitted with our specialized RAP drying drum and mid-ring recycling system, plants can comfortably handle 50% to 60% RAP without blue smoke emissions or binder oxidation.
Standard manufacturing lead time for OEM stationary batch plants ranges from 30 to 45 days. Portable mobile plants can ship within 25 to 30 days. Site erection, wiring, calibration, and operational trial runs typically require 14 to 21 days depending on local civil foundation readiness.
We maintain regional spare parts warehouses across Russia, South Africa, Malaysia, Kenya, and Uzbekistan. Critical wear items—such as mixer paddle tips, screen meshes, burner nozzles, and pneumatic valves—can be dispatched within 24 hours. Express air freight and dedicated local service teams minimize equipment downtime.
We use a dual-stage dust collection system combining a primary structural cyclone separator (collecting coarse particles and returning them to hot elevators) with a high-temperature Nomex baghouse filter. This system achieves exhaust gas dust concentrations under 10 mg/Nm³, fully compliant with European and North American air quality mandates.
