High-performance machinery designed for micro-surfacing, slurry sealing, cold recycling, and precision pavement engineering.
Decades of Academic Research, Industrial Rigor, and High-Tech Manufacturing
Founded in 1998 as Xi'an Hongda Communications Technology Co., Ltd. by a distinguished group of academic professors from Chang'an University alongside leading highway engineering experts, the HEM Group stands as one of China's earliest high-tech enterprises dedicated to the independent research, design, and manufacturing of road maintenance machinery. Combining theoretical rigor from China's top transportation engineering institution with field-tested manufacturing prowess, HEM Group has redefined modern pavement maintenance.
Recognized officially as a High-Tech Enterprise by the Shaanxi Provincial Department of Science and Technology in 2006, the group expanded its international footprint in 2017 by establishing its specialized export sales wing, HME TOP Machinery Equipment Co., Ltd. This division oversees international technical exchanges, product export operations, global spare parts distribution, and round-the-clock technical support for contractors across the globe.
Preventative Maintenance Protocols engineered to double highway lifespan while reducing lifecycle carbon footprints by up to 45%.
As global road networks age under heavier traffic loads and severe climate fluctuations, traditional reactive maintenance—such as thick hot-mix asphalt overlays—is no longer cost-effective or environmentally sustainable. Modern highway agencies and private concessions rely on Slurry Seal and Micro-Surfacing technologies to deliver rapid, durable, and highly skid-resistant surface renewals.
Designed for heavy-traffic highways and expressways. Utilizes polymer-modified asphalt emulsion (PMA), 100% crushed high-hardness aggregate, mineral filler, water, and specialized additives mixed continuously on-site. Enables quick traffic restoration within 1 hour.
Combines simultaneous bitumen spraying and aggregate spreading in a single chassis pass. Ensures optimal binder-to-stone bonding, sealing micro-fissures, preventing moisture ingress, and restoring macro-texture to weathered pavements.
Mills existing distressed asphalt pavements, grinds material on-site, mixes it with emulsified asphalt or cement foaming agents, and repaves it immediately. Reduces raw material procurement costs by over 50%.
HEM Group’s manufacturing backbone relies on digitalized assembly workflows, automated robotic welding stations, laser-guided cutting systems, and stringent post-assembly hydraulic pressure testing. By maintaining absolute control over key component production—such as specialized twin-shaft continuous mixers, variable-displacement hydraulic pumps, and micro-computer dosing units—our equipment delivers unmatched reliability under extreme working environments ranging from -30°C in Siberian cold zones to +50°C in Middle Eastern deserts.
From Earthmoving to Aggregate Processing and Precision Paving
Featuring mini-excavators (e.g., R319, R322L), wheel loaders, backhoe loaders, and heavy bulldozers designed for site preparation, foundation trenching, and utility construction.
Complete product lines including Intelligent Bitumen Distributors, Slurry Seal Pavers, Asphalt Milling Machines, Slip-Form Concrete Pavers, and Road Wideners (DK1800).
Heavy-duty Mobile Primary Jaw Crushers, Screen Machines, and Mobile Vibrating Screens engineered for quarrying, mining, and reclaimed asphalt pavement (RAP) sizing.
Driving Next-Gen Road Maintenance through Automation, AI Telematics, and Sustainable Engineering
As the international transportation sector shifts toward decarbonization and intelligent infrastructure, HEM Group’s engineering roadmap is focused on four core technology pillars:
Integrating real-time laser moisture sensors and automatic viscosity adjustments directly into slurry mix tanks to compensate for aggregate moisture fluctuations dynamically during paving operations.
Replacing traditional auxiliary diesel engines in slurry pavers and bitumen sprayers with lithium-ion hybrid power units, cutting noise pollution by 35% and job-site carbon emissions by up to 25%.
Providing global fleet operators with real-time cloud tracking of material consumption rates, hydraulic temperatures, pump flow rates, and preventive maintenance alerts via satellite links.
Upgrading pump seals, tank heating elements, and mixing paddles to ensure seamless operation with next-generation bio-based binders and high-concentration crumb rubber modified asphalt.
Serving clients across 60+ countries with localized service hubs, swift customs documentation, and genuine spare parts delivery.
To support major highway projects worldwide, HEM Group has established localized distribution centers and technical service teams in key strategic markets including Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka. Our international sales organization handles end-to-end logistics, complete customs documentation, export compliance certificates, and rapid air-freight shipment of critical wear components.
