Explore our premium machinery portfolio designed for road rehabilitation, bitumen processing, and high-durability infrastructure development.
Asphalt pavement assets constitute the backbone of global economic productivity. Over time, environmental stressors such as UV oxidation, moisture infiltration, and heavy axle loading induce mechanical degradation, leading to micro-cracking, raveling, and rutting. To combat pavement distress, modern highway engineering has shifted from reactive reconstruction to proactive pavement preservation. As a primary China Asphalt Treatment Manufacturer & Supplier, HEM Group (originally founded in 1998 by professors from Chang'an University—the elite cradle of Chinese highway engineering) stands at the forefront of this industrial transition.
Sustainable pavement management relies on optimizing the Life Cycle Cost (LCC) of highway networks. Integrating high-performance thermal decanting, precise polymer modification (SBS/CRMB), cold in-place recycling (CIPR), and micro-surfacing techniques can extend pavement service life by 8 to 12 years while reducing embodied carbon emissions by up to 45% compared to conventional hot-mix asphalt (HMA) overlays.
Founded by university researchers specializing in mechanical dynamics, engine power matching, hydraulic transmission, and digital CAN-bus control systems. Every piece of equipment is backed by empirical testing and scientific research achievements.
Utilizing high-precision CNC laser cutting, robotic welding cells, dynamic balancing test rigs, and automated hydraulic calibration facilities spanning over 5,000 square meters of production space.
From primary bitumen melting decanters and polymer modification plants to intelligent bitumen distributors, pavers, chip sealers, and mobile aggregate crushing units.
International civil engineering contractors and municipal public works departments require asphalt processing machinery that delivers consistent material performance across harsh operating environments—from sub-zero alpine passes to high-humidity equatorial regions.

The global dominance of Chinese asphalt treatment equipment stems from a concentrated manufacturing ecosystem that combines industrial scale with extreme engineering agility. As an established manufacturer, HEM Group leverages these structural advantages to offer world-class reliability at a highly competitive Total Cost of Ownership (TCO).
Our road machinery integrates global Tier-1 hydraulic components (Rexroth, Danfoss, Parker) with proprietary digital CAN-bus electronic control architecture. This dual approach guarantees micro-second response times for bitumen pump displacement, screed tamper frequencies, and binder distribution metering.
Overheating bitumen causes irreversible thermo-oxidative aging, degrading the binder's penetration index and ductility. Our drum decanters and modified asphalt plants utilize indirect heat-transfer oil circulation system coils. This design prevents direct flame impingement, protecting binder chemistry and reducing energy consumption by up to 28%.
Whether operating in the hyper-arid deserts of the Middle East or high-altitude, low-oxygen mining roads in the Andes, our engineering team customizes power-matching profiles, cooling package capacities, dust-proofing seals, and wear-resistant alloy coatings (Hardox steel liners) to meet unique field requirements.
Every unit undergoes strict quality assurance protocols, including hydrostatic pressure testing of bitumen lines, 24-hour thermal loop stress testing, and dynamic load calibration prior to port dispatch. All equipment fully complies with CE, ISO9001, and international environmental emissions standards.
Our specialized road machinery and aggregate processing units are deployed across diverse global infrastructure projects:
Cold In-Place Recyclers and high-torque asphalt pavers operate effortlessly on steep gradients and low-oxygen altitudes, enabling localized pavement recycling without long-distance material hauling.
Intelligent Bitumen Distributors and Micro-Surfacing Pavers deliver ultra-smooth, high-friction surface courses during limited overnight lane closure windows, minimizing traffic disruption.
Heavy-duty mobile jaw crushers and soil stabilizers reinforce heavy haulage routes subject to extreme axle loads, preventing structural subgrade failure in remote mining operations.
HEM Group was founded by a group of professors from Chang'an University and experts in the road building industry in 1998, originally established as Xi'an Hongda Communications Technology Co., Ltd. It is one of the earliest high-tech enterprises focusing on independent research and design of road construction equipment in China.
Since its inception, the company has adhered to high-tech research and development with the goal of creating an international brand for Chinese construction machinery. Focusing on high-end road maintenance machinery, HEM Group holds numerous invention patents and scientific achievements across mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems. In 2006, the company was officially recognized as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology.
In 2017, to expand international trade and technical exchange, HME TOP Machinery Equipment Co., Ltd. was established as the group's dedicated export sales company, managing overseas distribution, logistics, international technical support, and after-sales service.

Our DT Series Drum Decanters utilize a dual heating architecture combining closed-loop thermal oil coils with redirected engine exhaust heat. The enclosed melting chamber captures radiant heat, preventing thermal loss. The automated hydraulic pusher mechanism delivers smooth drum movement, achieving melting rates of 10 to 18 tons per hour while preventing thermal cracking or oxidation of the bitumen binder.
Our distributors feature a closed-loop radar-based speed sensing system paired with a computer-controlled variable displacement hydraulic bitumen pump. As vehicle speed changes, the system instantly adjusts pump output to maintain exact target spraying rates (e.g., 0.5 kg/m² to 2.5 kg/m²) across every nozzle, keeping application tolerance within ±1.5%.
Yes. Our multi-functional modified asphalt plants feature a high-shear colloid mill engineered with specialized rotor-stator geometry operating up to 3000 RPM. This setup reduces SBS polymers, crumb rubber from recycled tires, and EVA additives down to sub-micron particle sizes, producing homogeneous modified binder emulsions with superior storage stability and high softening points.
We offer comprehensive OEM customization, including engine selection (Cummins, Weichai, Deutz meeting Tier 3/Stage V emissions), custom chassis mounting (HOWO, ISUZU, MAN, Mercedes-Benz, or trailer-mounted), specialized insulation packages for extreme cold regions, and custom operator interface languages for our CAN-bus touchscreen systems.
