Asphalt Crack Filler Machines

Project Background: Preventive-maintenance project for 19 km provincial & county-town roads in Eastern Uganda. Crack spots were widely scattered. Local logistics lacked heavy-duty transport trucks. Huge tropical day-night temperature swing and long spare-part lead-time required lightweight tow-behind filler to cut transport and material cost.

 Project Location: Provincial & county-town roads, Eastern Region, Uganda

Challenges

1. Scattered work sites made truck-mounted heavy fillers impractical. Special large vehicles brought high transport expenses.

2. Poor temperature control on legacy machines frequently burnt sealant under high temperature or left it under-melted in cool conditions, causing heavy material waste.

3. Submerged built-in pump required complicated kettle disassembly for repair. Field sites had limited maintenance support and suffered long-time shutdown after breakdown.

4. Numerous curve and diagonal cracks. Limited hose rotation forced frequent machine repositioning and lowered productivity.

5. Primitive site conditions made tool-carrying inconvenient. High feeding port increased worker fatigue and scald risk.

Solution: Three FND-TG200 tow-behind crack fillers were deployed. Dual tow-behind / hand-push mode with heavy-duty tires suited rough rural roads without heavy-duty trucks. Dual-digital temperature display plus indirect thermal-oil heating stabilized sealant status. Gun-handle electric switch minimized dripping waste. External reversible oil-circulation pump enabled simple field service. 5.5-m 270° rotatable hose handled multi-directional cracks. Low-level splash-proof feeding port plus full insulation improved safety. Built-on-board toolbox stored service accessories.

Project Outcome: Ordinary utility vehicles completed machine towing without dedicated heavy trucks. Sealant burning and incomplete-melting incidents dropped significantly. Pump faults could be resolved on-site without prolonged halt. Less machine repositioning improved daily working mileage. Full 19 km crack-sealing finished on-schedule. Sealed joints remained solid through rainy seasons and protected road subgrade effectively.

The equipment warranty period is 12 months, calculated from the date of equipment ex-factory. For product quality defects, the Supplier shall provide maintenance guidance via telephone; on-site service is not included under warranty. Should on-site service be required, it shall be subject to mutual negotiation between both parties, and the Buyer shall bear all relevant travel and accommodation expenses. For component-related quality failures occurring within the warranty period, free repair or replacement shall be available upon mutual agreement with the Supplier. Wear-and-tear parts are excluded from this warranty.

The Supplier shall arrange logistics to deliver the equipment to the location designated by the Buyer. Freight costs shall be borne by the Buyer. The Buyer shall be responsible for the unloading and acceptance of the equipment.
