Explore our factory-direct synchronized chip sealers, mobile crushing plants, rollers, and paving machinery designed for global high-efficiency road construction projects.
In the era of modern pavement asset management, global highway authorities and municipal engineering firms face an imperative challenge: maintaining structural road longevity while curbing capital expenditure and environmental impact. Preventative road maintenance has shifted from reactive resurfacing to high-precision Synchronized Chip Sealing technology. As a premier High-Quality Chip Sealer Supplier & Factory, HEM Group (HME TOP Machinery Equipment Co., Ltd.) stands at the forefront of this industrial transition.
Synchronized chip sealing integrates bitumen binder spraying and aggregate chipping into a single-pass operation. By reducing the time delta between binder application and aggregate embedding to less than 0.5 seconds, initial adhesion is increased by 95%, virtually eliminating aggregate loss under high-speed traffic.
Compared to traditional hot-mix asphalt overlays (HMA), chip seal applications reduce carbon emissions by over 60% and lower material consumption by up to 70%. This makes synchronized chip sealing the gold standard for green highway infrastructure projects worldwide.
Equipped with radar speed sensors and real-time PLC closed-loop control systems, modern chip sealers dynamically adjust bitumen spray volume and aggregate spread rates regardless of vehicle speed fluctuations, guaranteeing uniform coverage.
HEM Group was founded by a group of professors from Chang'an University (China's leading institution for highway engineering and machinery) and senior road building industry experts in 1998, originally established as Xi'an Hongda Communications Technology Co., Ltd. We represent the earliest high-tech enterprise dedicated to independent research, development, and design of road construction and maintenance machinery in China.
Since our inception, HEM Group has adhered strictly to technological innovation and high-tech R&D. Aiming to build a globally recognized brand for Chinese construction machinery, we focus on high-end road maintenance equipment. Over the past two decades, our research team has secured numerous national invention patents and breakthrough scientific achievements in mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control.
In 2006, HEM was officially designated as a "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology. To further streamline international trade, technical exchanges, and global engineering support, we established our specialized export arm—HME TOP Machinery Equipment Co., Ltd. in 2017.
Today, we provide a complete one-stop chain for road construction and mining projects globally. Our full portfolio includes road milling machines, intelligent bitumen distributors, asphalt pavers, synchronized chip sealers, slurry seal machines, road wideners, paver feeders, mobile jaw crushers, mobile screening units, rollers, excavators, and genuine OEM spare parts.
Procuring heavy road construction machinery directly from top Chinese factories offers unparalleled commercial and technical benefits for global engineering contractors. Through systemic digital transformation and automated supply chain clusters, HEM Group delivers superior equipment at highly competitive Total Cost of Ownership (TCO).
From raw structural steel laser cutting to robotic frame welding and dynamic hydraulic load testing, our 50,000 m² smart factory ensures 100% quality traceability across every component of our synchronized chip sealers and bitumen distributors.
We partner with premier global hydraulic and electronic component suppliers (such as Rexroth, Danfoss, Schneider, and Cummins engines) to ensure seamless cross-border serviceability and extreme equipment reliability under harsh site conditions.
Whether adapting chassis dimensions for localized regional axle load regulations, designing specialized heat insulation for sub-zero climates, or modifying spray bar widths, our engineering team tailors equipment to specific tender requirements.
Highway departments, municipal authorities, and international private paving contractors utilize HEM Group's chip sealers across diverse geographic environments. Below are key field deployment scenarios:
Challenge: Micro-cracking and surface oxidation on high-speed expressways cause moisture infiltration, leading to structural base failure.
Solution: Applying a synchronized polymer-modified bitumen chip seal (using the SS6000 self-propelled chip spreader) seals hairline cracks instantly, restores macro-texture anti-skid friction, and extends pavement service life by 5-8 years at a fraction of resurfacing costs.
Challenge: Budget-constrained regional road agencies require cost-effective paving solutions for unpaved gravel roads.
Solution: Double-pass synchronized chip sealing directly over compacted aggregate bases provides a durable, dust-free, and waterproof wearing course, enabling rapid electrification and rural revitalization transport networks.
Challenge: Extreme axle weights from heavy container handlers and mining haulers cause rapid pavement rutting and shear failure.
Solution: High-binder rubber-modified chip seal coats create a stress-absorbing membrane interlayer (SAMI) that prevents reflective cracking beneath heavy-duty asphalt layers.
Challenge: Bitumen breakdown in arid desert regions (>50°C surface temp) or thermal cracking in sub-zero alpine corridors.
Solution: HEM chip sealers feature dual diesel burners, heat oil circulation systems, and thermostatic spray controls, maintaining ideal binder viscosity regardless of ambient weather extremes.
