Discover our leading high-efficiency road construction and paving machinery designed for heavy-duty infrastructure projects worldwide.
The history of HEM Group represents over two decades of technical breakthrough in Chinese highway engineering machinery. Founded in 1998 by distinguished professors from Chang'an University—the world-renowned epicenter of road construction science—our company was initially established as Xi'an Hongda Communications Technology Co., Ltd. We are proud to be the earliest pioneer dedicated to independent research and design of specialized road paving and maintenance equipment in China.
In 2006, our relentless commitment to scientific innovation earned us official recognition as a High-Tech Enterprise by the Shaanxi Provincial Department of Science and Technology. To further streamline global operations, custom technical consultations, and international machinery export sales, HME TOP Machinery Equipment Co., Ltd. was established in 2017 as our dedicated export enterprise.
Today, our engineering portfolio integrates mechanical dynamics, digital load-sensing hydraulics, engine-power matching algorithms, and automated electric control systems into every asphalt plant, paver, distributor, and milling machine we manufacture.
Modern highway infrastructure demands higher pavement longevity, zero-defect smoothness (IRI < 0.8 mm/m), low-carbon warm-mix processing, and intelligent paving automation. As a specialized OEM asphalt paving supplier, our R&D roadmap targets four foundational technical frontiers:
Integration of non-contact ultrasonic leveling sensors, pulse-width modulation (PWM) tamper bar frequency adjustment, and infrared thermal imaging screeds to prevent thermal segregation during hot-mix asphalt (HMA) laydown.
High-shear colloid milling systems engineered specifically for SBS, SBR, and crumb rubber asphalt modification, ensuring homogeneous dispersion and high thermal stability under heavy axle traffic loading.
Advanced recycling trains equipped with foam bitumen expansion chambers, enabling 100% reclaimed asphalt pavement (RAP) structural rehabilitation with up to 45% reduction in lifecycle fuel expenditure.
CAN-bus 2.0 digital telemetry streaming real-time hydraulic pressure, engine load factor, asphalt temperature distribution, and aggregate feed ratios directly to cloud monitoring dashboards.
| Paving & Equipment Parameter | Conventional OEM Standards | HEM OEM / HME TOP Next-Gen Standard | Engineering Gain / Advantage |
|---|---|---|---|
| Screed Compaction Density | 82% - 86% pre-compaction | 90% - 94% High-Density Double Tamper | Reduces roller passes by 30%, increasing surface smoothness. |
| Spray Spray Metering Accuracy | ±5% Volumetric Tolerance | ±1% Radar-Synchronized Closed Loop | Eliminates bitumen flushing and streak fatting on road surfaces. |
| Polymer Shear Milling Fineness | Passes 80% < 5μm in 3 passes | Passes 98% < 5μm Single Pass High-Shear | Saves polymer modifier additives while raising softening points. |
| Hydraulic System Thermal Stability | Continuous operation < 75°C | Independent Variable Cooling < 62°C | Prevents seal deterioration during continuous 24-hour summer paving. |
Road contractors and government ministries require tailored equipment chains rather than standalone machinery. OEM Asphalt Paving Factory solutions by HEM Group provide end-to-end operational integration across four macro-construction sectors:
For high-volume multi-lane asphalt projects requiring high paving widths (up to 12 meters) and flawless longitudinal joints. Equipment stack includes High-Output Asphalt Mixing Plants, HDTV2500 Paver Feeders, Synchronized Chip Sealers, and Tandem Steel Drum Rollers.
Targeted preventive pavement maintenance solutions for city arterial roads and bridge decks. Utilizing Slurry Seal Pavers, Intelligent Bitumen Distributors, and Compact Road Milling Machines to minimize municipal traffic downtime.
Cost-effective road expansion for regional development. The DK1800 Multifunctional Road Widener and Cement Spreaders enable rapid gravel base placement, asphalt shoulder paving, and rural strip widening.
Operating a 5,000 square meter modern production base with an annual production output exceeding 5,000 machinery units, HEM Group ensures short lead times, precise component tolerance, and robust structural integrity across all product categories.
Our OEM manufacturing facility leverages robotic laser cutting, multi-axis CNC machining, automated shot-blasting, and heavy-duty paint curing lines. Every asphalt paving machine, mobile crusher, and excavator undergoes rigorous dynamic stress testing and hydraulic bench calibration prior to ocean shipment.
As a seasoned OEM asphalt paving manufacturer, we tailor machinery specifications to meet regional climate demands, localized emission standards (Stage II / Tier 3 / Tier 4 Final / Stage V), and specific contractor preferences.
Full private-label brand integration, corporate livery painting, customized control console interface graphics, and multi-language PLC software (English, Russian, French, Spanish, Arabic).
High-ambient tropical cooling packages for Middle Eastern operations (>50°C), thermal insulation jackets for cold-climate bitumen circulation systems in Arctic conditions.
End-to-end export processing including Form E, Certificate of Origin, Bill of Lading, Ro-Ro or Containerized packing, customs clearance, and global marine insurance coverage.
HEM Group machinery is actively operating across more than 60 countries and regions, including India, Sri Lanka, Indonesia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, Russia, Malaysia, Uzbekistan, Ghana, and Kenya. We maintain dedicated regional distribution hubs and technical spare parts warehouses to ensure zero jobsite downtime.

Addressing essential procurement, engineering compatibility, maintenance SLAs, and export compliance queries regarding OEM Asphalt Paving Machinery.
Our academic roots mean every piece of machinery design is validated through empirical highway dynamics and material rheology research. Unlike standard assembly factories, our R&D team includes pavement materials professors who optimize thermal dissipation in screeds, precise binder-aggregate spray ratios in chip sealers, and dynamic load balancing in pavers, directly resulting in longer pavement lifespans and lower contractor operating costs.
Our OEM workflow consists of four structured stages: (1) Technical Requirements Mapping (engine emissions, climate adaptations, control telemetry); (2) 3D CAD CAD/CAM Structural & Hydraulic Simulation; (3) Precision Factory Assembly with Quality Testing; and (4) Pre-Shipment Field Calibration. We accommodate custom branding, paint specifications, localized PLC digital interfaces, and specialized auxiliary attachments.
Through HME TOP Machinery Equipment Co., Ltd., we provide 24/7 technical hotline access, remote diagnostics, and prompt spare parts dispatch. In key regional markets—such as Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka—our localized service teams offer on-site machinery commissioning, operator training, and localized parts warehousing to eliminate operational downtime.
Our modified asphalt plants feature high-shear colloid mills capable of micro-milling SBS and crumb rubber down to sub-5-micron particle sizes in a single pass. Paired with high-capacity thermal oil heating systems and automated additive dosing, our plants prevent polymer degradation and phase separation during transport and storage.
All machinery is manufactured in accordance with ISO 9001 and ISO 14001 certifications, with optional CE and EAC compliance for European and Eurasian Customs Union destinations. Ships via Roll-on/Roll-off (Ro-Ro), Flat Rack containers, or Breakbulk depending on unit dimensions, complete with protective anti-corrosion marine coatings.
