Road maintenance is the "invisible lifeline" of urban transportation systems. However, traditional pavement repair methods have long faced three core pain points:
· High cost: Each repair requires procurement of new asphalt binders and aggregates, combined with labor and machinery expenses, costing over ¥100 per square meter;
· Environmental impact: Milled asphalt waste is difficult to dispose of, with incineration or landfill causing significant pollution;
· Traffic disruption: Traditional repairs require road closures for hours, severely impacting urban mobility.
Driven by national "Double Carbon" goals, low-carbon and sustainable road maintenance technologies have become an industry imperative. Suzhou Fanuode Engineering Machinery Co., Ltd. has addressed this trend with its Hot-In-Place Recycling (HIR) Vehicle, which centers on "waste circularity, low-carbon efficiency" and delivers a transformative solution for the road maintenance sector. This equipment enables 100% recycling and reuse of aged asphalt pavement while integrating milling, mixing, and paving operations in a single pass, ushering in a new era of road rehabilitation.
The Fanuode HIR Vehicle's competitive edge lies in the synergy of four key systems:
· Integrated Single-Pass Operation: The vehicle integrates four core modules—infrared heating wall, precision milling head, continuous mixing chamber, and synchronous paver. Eliminating the need for multiple machines, it completes the full process from pavement heating and softening to recycled surface placement in one operation, reducing labor and time costs by 60% compared to traditional methods.
· Intelligent Temperature Control System: Equipped with high-precision infrared temperature sensors, it maintains real-time control of asphalt heating within ±5℃, ensuring aged binder is fully softened without thermal degradation. The resulting recycled pavement matches the structural strength of newly placed asphalt.
· Emission Reduction & Waste Circularity: A three-stage flue gas purification system (activated carbon filtration + water mist scrubbing) achieves over 95% removal of harmful volatile organic compounds (VOCs). Meanwhile, 100% of milled asphalt waste is recycled into new pavement, eliminating the environmental burden of traditional maintenance.
· Efficient Power Train: Powered by a National VI compliant diesel engine with a high-efficiency transmission system, the vehicle reduces fuel consumption by 20% compared to peer equipment, further lowering carbon emissions.
The Fanuode HIR Vehicle adapts to a wide range of maintenance scenarios with its flexible operation mode:
· Urban Arterial Road Rehabilitation: In a maintenance project for a major Suzhou arterial road, the Fanuode FND-TG1500 HIR Vehicle completed 5 km of pavement rehabilitation in just 72 hours, with traffic maintained on one lane throughout construction. Its 15-minute rapid mixing capability enabled a daily output of over 2,000 square meters, tripling efficiency compared to traditional equipment.
· Rural Road Preservation: Targeting thin-surfaced, low-bearing-capacity rural roads in northern Jiangsu, the HIR Vehicle adjusts aggregate-to-binder ratios to mix aged asphalt with minimal new material, cutting costs to 40% of traditional repair methods. In Suqian's rural road renewal project, it successfully rehabilitated 120 km of deteriorated pavement, saving the local government over ¥2 million in maintenance funds.
· Expressway Emergency Pothole Repair: During emergency repairs on the Beijing-Shanghai Expressway (Huai'an Section), the HIR Vehicle completed full pothole remediation—cutting, heating, mixing, and paving—in just 2 hours, compared to 8 hours for traditional methods. Its auxiliary heating system enables operation at temperatures as low as -10℃, ensuring winter construction quality.
· High-Altitude Plateau Operations: Customized for Tibet's high-altitude, low-temperature, oxygen-deficient environment, the HIR Vehicle features upgraded power system and thermal insulation. In the Lhasa-Shigatse Expressway maintenance project, it achieved over 90% of plain-region efficiency, overcoming altitude challenges and earning high praise from local transportation authorities.
