Explore our core industrial road construction and preventative pavement maintenance inventory engineered for high durability and operating efficiency.
Pavement preservation has shifted globally from reactive mill-and-overlay strategies to proactive, lifecycle-extending preventive maintenance. Modern civil engineering frameworks dictate that sealed cracks reduce sub-base water penetration by up to 90%, effectively preventing catastrophic freeze-thaw spalling, pothole formation, and structural fatigue. As municipal transport authorities and private civil contractors demand higher return on infrastructure investments, the global market for high-efficiency OEM Asphalt Crack Sealing Machines is witnessing unmatched growth.
Advanced hot-pour Crack Sealing Machines integrate dual-jacketed thermal oil heating systems, ensuring indirect heating of rubberized asphalt compounds. This prevents bitumen charring, maintains polymer integrity, and delivers rapid heating cycles under 45 minutes.
Digital micro-processing control units continuously monitor heat transfer oil, sealant melt chambers, and electrically heated application wands. Dual digital thermostatic displays eliminate operator error and material overheating.
Available in trailer-mounted, truck-skid, or self-propelled chassis configurations. Integrated electric hose reels and 360-degree rotating boom arms significantly reduce field labor fatigue and boost linear sealing speed.
China has established itself as the global epicenter for heavy construction machinery manufacturing. OEM buyers, municipal procurement contractors, and international distributors leverage Chinese manufacturing hubs not only for cost savings, but for unrivaled production agility, complete supply chain cluster access, and cutting-edge digital hydraulic integration.
Chinese direct manufacturing partners offer extensive bespoke options tailored to regional climate demands and contractor preferences:
By pairing Chang'an University academic dynamic research with automated laser cutting, robotic welding, and ultrasonic seam inspection:
HEM Group was founded by a group of professors from Chang'an University and leading experts in the road building industry in 1998, initially registered as Xi'an Hongda Communications Technology Co., Ltd. It stands as the earliest high-tech enterprise dedicated to independent research and design of specialized road construction and maintenance equipment in China.
Since its inception, the company has adhered strictly to high-tech R&D excellence to build an international benchmark brand for Chinese construction machinery. Focusing on high-end road maintenance machinery, HEM has secured a series of national invention patents and scientific research breakthroughs in mechanical dynamics, engine power matching, hydraulic transmission, and digital electronic control technology. In 2006, HEM was recognized as a official "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology.
In 2017, to expand global trade networks, the group established HME TOP Machinery Equipment Co., Ltd., acting as the dedicated international sales arm responsible for global technical exchanges, self-operated product export/import, spare parts supply, and technical after-sales assistance.
Our complete equipment fleet supports civil infrastructure development across three main industrial divisions:
We supply wheel loaders, excavators, backhoe loaders, motor graders, and custom modified attachments. Operating globally across highway grading, bridge abutments, tunnel building, seaport logistics parks, real estate development, and agricultural land reclamation.
Specialized machinery portfolio including Asphalt Mixing Plants, Asphalt Pavers, Bitumen Distributors, Road Milling Machines, Paver Feeders, Micro-Surfacing Pavers, Synchronized Chip Sealers, Vacuum Sweepers, Crack Sealing Machines, and Snow Removal Equipment.
Heavy-duty aggregate machinery including Mobile Primary Vibrating Screens, Mobile Jaw Crushers, Mobile Cone/Roller Crushers, and complete crushing-screening plants tailored for quarrying, mining extractions, and recycled concrete processing.
Manufacturing experience backed by senior engineering professors from Chang'an University.
Complete tech support regarding bitumen modifiers, hot pour sealant specs, and application standards.
Bespoke engineering design for specialized regional pavement work and climate adaptation.
Round-the-clock digital troubleshooting, live video inspection, and rapid on-site operator training.
Our heavy machinery and crack sealing systems are successfully exported to over 60 countries and regions globally, including India, Sri Lanka, Indonesia, Nigeria, South Africa, Eritrea, Mozambique, Congo, Australia, Fiji, Bolivia, Russia, Malaysia, Uzbekistan, Ghana, Kenya, and beyond.
We maintain active regional distribution partners and dedicated field service centers across key international hubs to ensure fast dispatch of OEM spare parts and technical engineers to minimize machine downtime.
Indirect heating uses thermal transfer oil circulating around the sealant tank. This ensures uniform heat distribution up to 200°C without localized hot spots, preventing rubberized bitumen breakdown, coking, and wand nozzle clogging common in direct-fire units.
For municipal parking lots and localized city street repairs, compact 100L–200L walk-behind or trailer models are ideal due to high maneuverability. For major highway expansion projects or airport runway maintenance, 350L–1000L self-propelled or truck-mounted melters equipped with dual wands maximize daily production output.
We provide comprehensive OEM/ODM solutions: engine selection (Honda, Yanmar, Kohler, Kubota), Italian Riello burner integration, custom voltage/hydraulic pump configurations, private label branding, color matching, and localized user manual translations.
A compressed air heat lance removes moisture, debris, and vegetation while pre-warming the asphalt crack faces. Applying sealant to warm, dry concrete or asphalt surfaces improves bonding adhesion by over 80%, preventing premature pull-out during winter freeze cycles.
We provide a 12-month full machine warranty on core hydraulic and structural components. Replacement parts (pumps, hoses, burner nozzles, controllers) are dispatched via DHL/FedEx express within 24 hours from our regional warehouses or main production facility.
