Engineered for precision binder application, high thermal efficiency, and rigorous road construction specs.
In modern asphalt pavement engineering, the distribution accuracy of liquid binder (bitumen emulsion, hot modified asphalt, or rubberized asphalt) dictates the structural longevity and anti-stripping capabilities of the road surface. A Bitumen Pressure Distributor serves as the technological core for prime coat, tack coat, and surface treatment operations. Modern highway standards require precision distribution within tolerances as tight as ±2%, eliminating asphalt streaks, fat spots, and dry areas that lead to premature fatigue cracking and pothole formation.
As a premier China Bitumen Pressure Distributor Manufacturer & Factory, our engineering paradigm merges mechanical dynamics, precise engine power matching, hydraulic proportional control, and micro-computerized PLC metering. By leveraging continuous technological advances rooted in research partnerships with leading transport engineering academic institutions (including Chang'an University), Chinese OEMs have transitioned from basic mechanical spray bars to automated smart distributors with automatic nozzle control, thermal oil circulation systems, and real-time radar velocity feedback.
Technical Information Gain: Standard asphalt distributors suffer from binder cooling in spray nozzles during pauses. Intelligent systems utilize continuous thermal oil circulation throughout the entire spray bar manifold, ensuring instant nozzle readiness and zero cold-clogging at start-up.
Deciphering the hydraulic, thermal, and electronic control subsystems engineered inside Chinese manufacturing hubs.
Integrates Doppler radar speed sensors with proportional hydraulic pumps. As the vehicle's driving speed fluctuates, the PLC computer instantly adjusts the asphalt pump displacement to maintain exact binder application rates ($kg/m^2$).
High-efficiency automatic Italian Riello burners coupled with heat-transfer oil jacketed pipelines. Ensures rapid heating of high-viscosity modified bitumen up to 180°C–200°C without localized asphalt carbonization.
Custom-designed pneumatic spray nozzles configured for exact 1-to-3 spray fan overlap. Eliminates streak patterns and guarantees uniform transverse distribution across variable width extensions up to 6 meters.
Operators can configure spray width, individual nozzle activation, target application density, and pump speeds directly from an ergonomic color touchscreen inside the air-conditioned cabin.
Equipped with a pneumatic diesel flushing system. Following spraying operations, compressed air combined with diesel solvent cleans out internal piping and spray bars within 3 minutes, preventing bitumen hardening.
Reinforced steel tank insulated with high-density rock wool lining (50mm–80mm) wrapped in polished stainless steel outer cladding. Heat loss rate is maintained under 1°C–2°C per hour during long-distance transit.
HEM Group was founded by a group of professors from Chang'an University and seasoned experts in the road building industry in 1998 (originally established as Xi'an Hongda Communications Technology Co., Ltd.). It represents one of the earliest high-tech enterprises focusing on independent research and design of road construction and maintenance equipment in China.
Since its inception, the company has adhered to the principle of being guided by high-tech research and development and aiming to create an international brand for Chinese construction machinery. We focus on the research and development of high-end road maintenance machinery products, securing a series of national invention patents and scientific research achievements in mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control technology. In 2006, we were recognized as a "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology.
In 2017, to strengthen international technical exchanges and trade, the company established its dedicated global export arm, HME TOP Machinery Equipment Co., Ltd., which handles international sales, customized engineering export solutions, technical support, and global after-sales operations.

Watch our road maintenance machinery undergo field operation tests and factory calibration.
International highway tenders across Southeast Asia, Africa, Eastern Europe, and Latin America are increasingly specifying stringent binder spraying uniformity criteria. Global EPC contractors prioritize distributors equipped with telemetry systems, eco-friendly low-emission heating burners, and modular spray bar extensions that adapt quickly to variable lane widths without manual toll-booth stoppages.
Key technological vectors reshaping the bitumen pressure distributor market include:
Our equipment exports span more than 60 countries and regions, including India, Sri Lanka, Indonesia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, Russia, and Central Asia.
Collaborating with international infrastructure firms, regional dealers, and municipal construction authorities.












Technical and purchasing insights for equipment managers, highway engineers, and procurement directors.
Our intelligent bitumen distributors achieve a spraying distribution error margin of less than ±1.5% to ±2%. This is accomplished via closed-loop Doppler radar vehicle speed tracking integrated with a high-precision hydraulic proportional asphalt pump metering system.
Yes. Our heavy-duty bitumen pressure distributors are built with heat-transfer thermal oil jackets surrounding the asphalt pump, main valve manifolds, and spray bars. Combined with automatic dual diesel burners, the system maintains binder temperatures up to 200°C, efficiently handling modified asphalt, SBS, emulsified bitumen, and heavy rubberized binders.
Each pneumatic nozzle on the spray bar can be individually switched on or off via the smart touchscreen interface in the driver's cabin. This allows full control over spray width, section spraying, and overlapping without needing manual adjustments outside the truck.
We provide custom mounting options for all major global and domestic truck chassis brands, including SINOTRUK HOWO, SHACMAN, DONGFENG, FOTON, ISUZU, VOLVO, MAN, and Mercedes-Benz. Tank capacities range from 3,000 Liters up to 18,000 Liters depending on axle payload limits.
Our machines incorporate an automated dual cleaning protocol: a high-pressure diesel flushing cycle combined with compressed air blow-out. This purges remaining bitumen from nozzles and distribution manifolds in less than three minutes, preventing cold asphalt buildup.
