Direct OEM solutions optimized for asphalt synthesis, high-precision chip sealing, and road surface maintenance.
Founded in 1998 by distinguished professors from Chang'an University—China's premier academic institution for highway engineering and machinery—HEM Group (originally Xi'an Hongda Communications Technology Co., Ltd.) stands as a pioneer in road construction machinery R&D.
With over two decades of mechanical dynamics, engine power matching, hydraulic transmission, and digital electronic control innovations, we provide full spectrum OEM manufacturing for global paving projects. In 2017, HME TOP Machinery Equipment Co., Ltd. was formed as our dedicated international trade enterprise, delivering complete machinery supply chains worldwide.
Navigating modern infrastructure demands: Carbon-neutral asphalt, high RAP ratios, and polymer-modified bitumen integration.
Modern heavy-duty transport corridors demand Polymer Modified Bitumen (PMB) and Crumb Rubber Modified Asphalt (CRMA) to combat rutting, fatigue cracking, and moisture damage. Standard paving materials no longer survive extreme wheel loads, requiring specialized high-shear modification plants during binder preparation.
Global ESG imperatives are driving contractors away from total pavement reconstruction toward Cold In-Place Recycling (CIPR). Reclaiming existing aggregate beds with bitumen emulsion or foamed asphalt reduces carbon footprints by up to 45% while preserving virgin material reserves.
Preventive road asset management utilizes Synchronized Chip Sealers and Slurry Seal Pavers to extend pavement service life by 5–8 years at a fraction of resurfacing costs. Precise micro-dosing of binders and immediate aggregate placement are critical for high-speed expressways.
Architecting intelligent, automated, and zero-emission road paving machinery ecosystems.
Real-time infrared thermal imaging integrated into asphalt pavers to eliminate thermal segregation and ensure uniform compaction across variable ambient temperatures.
GNSS-guided automated screed control and millimeter-accurate total station integration for error-free longitudinal slope and cross-slope paving.
Transition of auxiliary hydraulic pumps and propulsion units to high-torque electro-hydraulic systems, slashing fuel usage and site acoustics in urban sectors.
Ultra-high-shear bitumen modification technology dispersing nano-silica and recycled plastic polymers for extreme freeze-thaw climate resistance.
Engineered to adapt to extreme global topographies, thermal environments, and jobsite requirements.
High humidity and salty maritime air accelerate aggregate stripping. Our slurry seal pavers and asphalt emulsification plants utilize specialized anti-stripping agent dosing systems and stainless steel fluid conduits, guaranteeing binder-aggregate adhesion under monsoonal rains.
Extreme ambient heat causes pavement bleeding and soft binder deformation. HEM Group’s OEM asphalt mixing plants incorporate high-efficiency thermal oil heating and precise aggregate screening to formulate stiff SBS-modified binders capable of handling continuous ambient temperatures exceeding 50°C.
Low oxygen and sub-zero temperatures cause severe freeze-thaw cracking. Our compact road cold recyclers and heavy-duty SD8B bulldozers feature turbocharged engines calibrated for high-altitude power retention and specialized rubber-modified asphalt paving screeds.
Leveraging cluster industrial ecosystems, fully integrated R&D, and cost-effective precision engineering.
Situated within Shaanxi's advanced machinery cluster, we source certified structural steel, Rexroth-grade hydraulic components, and Cummins/Weichai power units directly from strategic partners, eliminating component lead-time bottlenecks.
Unlike rigid Western manufacturers, our Chang'an University engineering team quickly adapts equipment blueprints to local jobsite specs, offering custom hopper capacities, dual-fuel heating systems, and customized electrical architectures.
Every asphalt plant module, chip spreader, and road milling machine undergoes dynamic dynamic-load testing, hydraulic stress analysis, and thermal sensor calibration before leaving our factory floor.
Inside our heavy machinery fabrication centers and global project deployments.
End-to-end export logistics, overseas field engineering, and lifetime technical support.
From CE, ISO, and EAC certifications to custom clearance documentation, our experienced logistics department ensures smooth customs entry into over 60 countries across Southeast Asia, Africa, Central Asia, Russia, and Latin America.
We maintain dedicated service centers and spare parts repositories across key markets including Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka to provide rapid on-site troubleshooting.
Our senior engineers provide on-site commissioning, machine operation training for localized workforces, and remote tele-diagnostics to maximize asset uptime and prevent jobsite operational downtime.
Key technical insights on OEM road paving material systems, equipment selection, and export support.
Polymer Modified Bitumen (PMB) enhances binder elasticity, temperature susceptibility, and resistance to rutting under heavy dynamic axle loads. In extreme thermal environments, PMB prevents pavement bleeding during summer heatwaves and resists low-temperature thermal cracking during winter cycles.
CIPR mills and pulverizes the existing damaged pavement layer on-site, mixes it with foamed bitumen or emulsifiers, and lays it down in a single continuous process. This eliminates the need to haul away old materials and transport virgin aggregate, reducing material costs by up to 40% and cutting project completion timelines significantly.
Yes. Backed by our Chang'an University engineering R&D origins, we specialize in custom machinery design. Whether customized screed widths, dual-purpose slurry/micro-surfacing configurations, or high-altitude engine recalibrations are needed, our factory delivers tailored OEM solutions.
