Explore our engineering lineup for asphalt production, road maintenance, and heavy equipment systems:
Modern highway infrastructure engineering demands unprecedented precision in bituminous aggregate batching. As global transport networks transition toward high-load freeways, airport runways, and heavy urban corridors, the reliance on high-capacity stationary asphalt mixing plants (ranging from 80 t/h to 400 t/h output) has become foundational. Unlike mobile or continuous drum plants, OEM stationary batch mixing plants allow micro-level aggregate screening, dual-stage dust filtering, and high-proportion Reclaimed Asphalt Pavement (RAP) integration without sacrificing mix volumetric integrity.
Designed with heavy-duty structural steel and containerized modules, stationary batch plants offer high structural rigidity, minimizing operational vibrations while simplifying transatlantic shipping and field assembly.
Utilizing high-efficiency burners compatible with Heavy Fuel Oil (HFO), Natural Gas, Coal Dust, or Biodiesel. Optimized flight designs inside the drying drum guarantee maximum heat transfer efficiency and low thermal loss.
Multi-deck vibrating screens deliver precise aggregate sizing into dedicated hot aggregate bins. Industrial load cells ensure batching tolerance within ±0.5% for bitumen, aggregates, and mineral fillers.
Backed by academic research from Chang'an University and over two decades of mechanical innovation:
A high-capacity OEM Stationary Asphalt Plant comprises six core interconnected subsystem modules engineered to operate under continuous heavy duty loads:
| Subsystem Module | Engineering Specifications & Mechanics | Key Operational Advantage |
|---|---|---|
| Cold Aggregate Feed System | Multiple hopper bins with frequency-controlled belt feeders, low-level warning sensors, and variable speed motors. | Ensures proportional feeding based on job-mix formulas (JMF), avoiding starved or overflow conditions. |
| Drying Drum & Burner Unit | Counter-flow design, heavy-duty gear ring drive, internal flight geometry customized for specific aggregate types, low-NOx combustion. | Maximizes heat exchange efficiency, reduces fuel consumption per ton of mixed asphalt, minimizes exhaust emissions. |
| Baghouse Dust Collection | Nomex heat-resistant filter bags, pulse-jet cleaning systems, micro-dust reclaim screw conveyors, dual-stage cyclone separation. | Achieves particulate emissions < 20 mg/Nm³, fully compliant with stringent global environmental standards (EPA/EU). |
| Vibrating Screen & Hot Bins | High-frequency enclosed vibrating screen (4-6 decks), thermal-insulated hot aggregate storage bins with continuous level indicators. | Guarantees exact particle size segregation prior to weighing, eliminating aggregate contamination. |
| Precision Weighing & Mixing Unit | Industrial lever load-cell weighing hoppers, twin-shaft compulsory pugmill mixer with wear-resistant Ni-Hard liner plates and paddles. | Produces a homogeneous asphalt mix within a 30-45 second mixing cycle, accommodating modified bitumen (SBS/Crumb Rubber). |
| Bitumen & Filler Storage Systems | Thermal oil heated bitumen tanks with automated temperature regulation, vertical filler silos with pneumatic fluidization. | Prevents bitumen aging and oxidation; ensures steady pneumatic delivery of mineral powder and hydrated lime. |
Stationary asphalt manufacturing plants serve as core infrastructure hubs in diverse regional operating environments. OEM customizations adapt equipment performance to local climatic conditions, material availability, and environmental codes.
High-tonnage continuous production (240 t/h - 400 t/h) designed to feed uninterrupted paver fleets during large-scale national highway upgrades. Compatible with polymer-modified asphalt (PMA) and SMA (Stone Matrix Asphalt) formulations.
Precision temperature control and strict aggregate grading capabilities required to meet airport pavement standards. Zero-segregation batching guarantees structural integrity capable of withstanding heavy aircraft loads.
Equipped with complete acoustic insulation enclosures, active blue-smoke filtration units, and odor reduction scrubbers for installation within suburban or urban zone boundaries.
Custom heat retention insulation, dust-proof PLC electrical cabinets with industrial HVAC cooling, and heavy-duty wear-resistant bucket elevators tailored for operations in Africa, the Middle East, and Southeast Asia.
Founded in 1998 by professors from Chang'an University—the premier academic institution for road highway engineering in China—our group (originally Xi'an Hongda Communications Technology Co., Ltd.) has evolved into a global leader in high-tech road construction equipment.
Since its inception, the company has adhered to high-tech research and development, aiming to build an international brand for construction machinery. We hold extensive patents in mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems. Recognized as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006.
In 2017, to serve international partners, HME TOP Machinery Equipment Co., Ltd. was established to handle global technical exchanges, export operations, field installation, and technical support.
Our complete machinery chain includes road milling machines, asphalt distributors, pavers, chip sealers, slurry seal pavers, road wideners, excavators, wheel loaders, and crushing/screening machinery.
Our road construction and asphalt batching equipment is exported to over 60 countries and regions including India, Sri Lanka, Indonesia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, and beyond.
As global environmental regulations tighten and digital twin automation matures, stationary asphalt batching plants are evolving toward zero-carbon and intelligent operation:
Transitioning from fossil fuels to green hydrogen combustion systems, reducing carbon emissions during aggregate drying down to zero thermal carbon intensity.
Integrating cloud-based neural networks that dynamically adjust burner flame length, cold feeder speeds, and batch mixing time based on aggregate moisture sensors.
Implementation of dual-drum recycling units and indirect hot-air RAP re-heating systems, preventing bitumen aging while maximizing recycled asphalt pavement usage.
