Explore our top-tier engineering machinery designed for driveway slurry seal, pavement maintenance, aggregate processing, and heavy construction projects globally.
HEM Group was founded by a group of professors from Chang'an University and experts in the road building industry in 1998, which was first called Xi'an Hongda Communications Technology Co., Ltd. It stands as the earliest high-tech company focusing on independent research and design of road construction 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, having obtained a series of 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 better strengthen international exchanges and trade, the company established a dedicated export sales company, HME TOP Machinery Equipment Co., Ltd., mainly responsible for international technical exchanges, import and export trade of self-operated products, after-sales service, and technical support.
Deep technical analysis of asphalt maintenance dynamics, preventive preservation economics, and factory-level slurry seal manufacturing infrastructure.
Slurry seal technology represents a cost-effective cold-mix paving treatment engineered to extend pavement lifecycle by 5 to 8 years. By applying a precisely proportioned mixture of modified asphalt emulsion, fine aggregate, mineral filler, water, and specialized additives, commercial driveway slurry seal equipment mitigates oxidation, seals micro-cracks, and restores surface friction at 30% of the cost of traditional asphalt hot-mix overlays.
While standard slurry seal relies on thermal evaporation for curing, advanced micro-surfacing systems designed by Chang'an University engineers utilize polymer-modified chemical-break emulsions. This allows quick-traffic return within 1 hour even in non-ideal environmental conditions. Our factory manufactures versatile pavers capable of handling both ISSA Type I, Type II, and Type III aggregate gradations with seamless recalibration.
The performance of driveway slurry seal hinges on strict aggregate-to-binder ratios. HEM Group machines incorporate proprietary hydrostatic dynamic drives and micro-computer controlled feed systems. This synchronization guarantees that dry aggregate mass, asphalt emulsion flow, water volume, and liquid additive percentages remain locked regardless of vehicle paving speed variations.

Leading the next generation of eco-friendly, digitally integrated pavement preservation equipment.
Future slurry seal pavers produced at our factory will feature fully autonomous batching adjustments using real-time infrared aggregate moisture sensors. As moisture content fluctuates in field aggregate hoppers, the onboard computer dynamically adjusts water pump stroke speed, ensuring strict water-cement-binder ratios without manual intervention.
In response to global carbon-reduction mandates for municipal residential work, HEM Group is developing hybrid electric slurry seal pavers. These units reduce noise levels below 65 dB during urban night operations and lower fuel consumption by up to 35% during continuous mixing cycles.
Our modified asphalt plants feature high-shear colloid mills capable of processing heavy SBS polymer and crumb rubber additives down to sub-micron particle sizes. This creates stable asphalt emulsions that resist phase separation, extending slurry seal shelf-life and bonding strength.
To eliminate aggregate streaking and ensure uniform mat thickness on rutted driveways, our team designed hydraulic variable-width spreader boxes equipped with multi-zone variable-frequency vibrators, maximizing surface density and seal impermeability.
