Explore our flagship heavy-duty machinery line designed for municipal maintenance, road rehabilitation, and large-scale highway infrastructure.
From reactive patch-and-run tactics to automated velocity spray injection and thermal reclamation systems.
Global municipal budgets are shifting heavily from road replacement to proactive preventative maintenance. Automated pothole patchers reduce repair cycle times by up to 70%, minimizing traffic disruption and operational hazards on urban expressways and rural arterial networks.
Modern pothole patchers utilize high-pressure air cleaning, specialized bitumen emulsion tack coating, and forced aggregate projection. This eliminates cold joint vulnerabilities and prevents water ingress, extending patch lifespans from months to years.
With rising labor costs worldwide, single-operator truck-mounted and trailer-assisted pot hole patchers significantly lower labor expenses while increasing daily repair throughput. Fleet managers prioritize equipment offering low fuel consumption and minimal maintenance downtime.
Rooted in Chang'an University road construction dynamic studies, our machinery incorporates advanced mechanical, hydraulic, and electronic control technologies.
Custom-engineered hydraulic systems optimize engine output across variable operation speeds. Proportional valve controls ensure smooth boom articulation, precise aggregate delivery, and constant emulsion pressure regardless of ambient temperature fluctuations.
Microcontroller-driven CAN-bus networks monitor aggregate feed rates, emulsion heating temperature, and blowout air pressure in real-time. Smart telemetry enables operational data logging, predictive maintenance, and precise material tracking for contracting compliance.
Equipped with ceramic heating elements and indirect heat transfer oil jackets, our units maintain bitumen emulsion at optimal spraying viscosity without scorching the material. Automatic thermal cutoff prevents binder degradation and extends component service life.
Engineered with wear-resistant steel hoppers, anti-clogging air locks, and high-velocity venturi blower systems, our patchers handle varied aggregate sizes (from 2mm to 10mm crushed rock) with smooth, continuous displacement.

Everything you need to know about specs, OEM customization, lead times, and international after-sales support.
Spray injection patching works via a 4-stage process using compressed air: First, high-pressure air clears water and debris from the pothole. Second, a light tack coat of hot asphalt emulsion is sprayed to seal the cavity. Third, aggregate coated with emulsion is forcefully injected into the pothole at high velocity, achieving dense mechanical compaction from the bottom up. Fourth, a dry top-coat layer of aggregate is applied to prevent tracking by passing vehicles.
Yes. As a primary OEM manufacturer, we design mounting frames and power take-off (PTO) interfaces compatible with all standard domestic and international truck chassis, including SINOTRUK, SHACMAN, ISUZU, MAN, DONGFENG, and VOLVO. Trailer-mounted and skid-mounted configurations are also readily available.
We maintain dedicated service centers and spare parts warehouses across key regions, including Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka. Furthermore, we offer 24/7 online technical support, video troubleshooting, and on-site engineering dispatch for complex installation projects.
Our patchers are compatible with rapid-setting cationic emulsified asphalt (such as CRS-2 or CSH) and polymer-modified bitumen emulsions. Aggregate sizes typically range from 4mm to 10mm crushed cubical stone with minimal fines for optimal compaction and bitumen adhesion.
Standard configurations are available for prompt shipment within 15 to 20 days. For custom OEM truck chassis adaptations or specialized color/branding requirements, lead time ranges between 30 and 45 days, complete with pre-shipment testing video documentation and quality verification certificates.
