Direct-from-factory high-performance paving, spraying, and asphalt manufacturing equipment designed for precise application and maximum fleet durability.
An Industry Benchmark Guide to Asphalt Pavement Preservation, OEM Equipment Innovations, and Fleet Optimization Strategy.
In modern transport asset management, Chip and Seal technology (Synchronized Bituminous Surface Treatment) stands out as one of the most cost-effective and structurally vital solutions for extending pavement service life. As a specialized OEM Chip and Seal Equipment Manufacturer, our engineering framework merges advanced dynamic metering, computer-controlled hydraulic synchronization, and real-time telemetry to overcome traditional field failures like aggregate stripping, binder streaking, and thermal degradation.
The performance of a bituminous surface treatment depends entirely on binder film thickness uniform distribution and immediate aggregate seating. Our self-propelled chip spreaders and synchronized chip sealers utilize positive-displacement gear pumps coupled with micro-computerized pulse-width modulation (PWM) spray bars. Each spray nozzle is individually controlled via CAN-bus network protocols, responding dynamically to vehicle ground speed variations monitored by radar speed sensors.
Simultaneously, the aggregate distribution hopper features helical metering rollers driven by independent hydraulic motors. By maintaining exact volumetric metering across widths ranging from 2.5 meters to 4.5 meters, our machinery prevents localized aggregate over-stacking, eliminating the risk of windshield damage caused by loose flying stones post-compaction.
Bridging Academic Mechanical Research with High-Output Manufacturing Since 1998.
HEM Group was founded in 1998 by a distinguished panel of engineering professors from Chang'an University—China's premier institution for highway engineering and transportation machinery—alongside senior road construction experts. Originally registered as Xi'an Hongda Communications Technology Co., Ltd., it stands as the earliest high-tech enterprise dedicated to independent design and engineering of advanced road construction equipment in China.
Guided by high-tech research and international quality standards, HEM Group has pioneered breakthrough patents in mechanical dynamics, engine thermal power matching, closed-loop hydraulic transmissions, and digital electronic control systems. In 2006, the Shaanxi Provincial Department of Science and Technology officially certified HEM Group as a High-Tech Enterprise.
To support expanding overseas infrastructure demands, HME TOP Machinery Equipment Co., Ltd. was established in 2017 as the group's dedicated global trade, engineering exchange, and international product sales arm, delivering seamless technical assistance, OEM customization, and localized product distribution worldwide.
Decarbonization, Telematics Automation, and Intelligent Material Flow in Road Maintenance Equipment.
Next-generation OEM Chip Sealers integrate real-time LiDAR terrain scanning and cloud-connected edge computing. Spray rates automatically adapt based on surface macrotexture variations, micro-milling depth analysis, and ambient temperature sensors.
Transitioning from traditional diesel burner units, our engineering roadmap incorporates high-efficiency electric thermal oil heating coupled with heat-recovery systems. This dramatically reduces carbon emissions while maintaining asphalt storage temperatures precisely at 160°C–180°C.
To support high-viscosity Crumb Rubber Modified Asphalt (CRMA) and bio-based binders, equipment spray pumps feature hardened anti-abrasion impellers and wide-orifice anti-clogging nozzles engineered for high-viscosity applications.
Engineered to Excel Across Extreme Climates, Varying Topography, and Regional Infrastructure Standards.
In high-altitude regions like the Andean corridor or Central Asian plateaus, reduced atmospheric pressure affects engine combustion while steep gradients challenge vehicle traction. Our Chip and Seal spreaders utilize turbocharged diesel powerplants with electronic engine-hydraulic load matching. All-wheel hydrostatic drive systems ensure consistent climbing power and uniform spray rates even on 12% road gradients.
For coastal tropical zones across Southeast Asia and West Africa, humidity accelerates binder emulsification failures while salt air induces rapid machine oxidation. HME TOP machinery features marine-grade anti-corrosion coatings, stainless-steel spray bars, and pressurized air-purging lines that clean bitumen lines immediately after work stops, preventing internal clogging.
Desert paving demands high ambient tolerance. Our auxiliary cooling systems prevent hydraulic fluid breakdown in temperatures exceeding 50°C. Insulated bitumen tanks feature double-layer rock wool insulation to hold asphalt temperatures stable over long-distance transit across vast arid territories.
For Northern European and North American freeze-thaw cycles, high-viscosity modified bitumen must be applied with rapid thermal transfer. Diesel thermal oil heaters generate up to 100,000 kcal/h, maintaining fluid mobility even during late-season maintenance campaigns in near-freezing ambient air.
