Explore our precision-engineered modified bitumen plants, paver series, and compaction units built for global infrastructure demands.
Founded in 1998 by distinguished professors from Chang'an University—the cradle of China's highway engineering and machinery development—HEM Group (originally Xi'an Hongda Communications Technology Co., Ltd.) stands as the pioneer in high-tech road machinery design and bitumen technology.
Recognized as a High-Tech Enterprise by the Shaanxi Provincial Department of Science and Technology in 2006, our research institute holds numerous national invention patents across mechanical dynamics, engine power matching, hydraulic transmission systems, and digital electronic metering control.
To streamline global procurement, export operations, and technical assistance, HME TOP Machinery Equipment Co., Ltd. was established in 2017 as our dedicated export sales division, delivering turnkey solutions across 60+ countries worldwide.
Quantifiable performance indicators representing over two decades of mechanical precision and worldwide industrial distribution.
The international road construction sector is experiencing a paradigm shift. Rising dynamic loads, severe climatic variations, and stringent carbon footprint regulations require modern liquid bitumen formulations and handling machinery to achieve unprecedented thermal stability and structural durability.
Styrene-Butadiene-Styrene (SBS) and high-viscosity additives enhance rutting resistance at high temperatures while mitigating low-temperature thermal cracking. Modern plants integrate high-shear homogenizers running above 4,500 RPM to guarantee continuous polymer dispersion.
Utilizing scrap tire rubber powder within liquid asphalt (CRM) drastically reduces noise emission and increases pavement fatigue life. Our specialized modified asphalt plants prevent phase separation through automated agitation and temperature-controlled curing tanks.
Transforming existing degraded pavements by injecting foamed liquid bitumen or emulsified asphalt on-site cuts raw aggregate consumption by 80% and reduces carbon emissions by over 65% compared to conventional hot-mix asphalt applications.
Comprehensive engineering benchmark parameters for industrial liquid asphalt modification, transport, and application machinery.
