Asphalt crack sealing melter and applicator YG series

manual

Product overview
In asphalt pavement maintenance, unsealed cracks allow water intrusion that causes subbase failure and potholes. A crack seal machine injects hot-applied modified bitumen or crack sealant deep into fissures under pressure to create a watertight bond and extend pavement life by 3–5 years at a fraction of the repaving cost.

Key benefits

• Reduce Maintenance Costs: Preventive sealing is far less expensive than large-scale asphalt repairs.
• Increase Daily Productivity: Professional crack sealing equipment with heated hoses can deliver 2,000–3,000 linear meters of output per day for typical crews.
• Extend Pavement Service Life: Properly applied hot-applied rubberized sealant prevents water damage and stops crack propagation.
• Field operator tips: Always clean and dry the crack first. Use a road router and hot air lance to remove dust and debris to improve sealant adhesion. Run the pump in reverse for ~60 seconds at the end of the day to clear residual material from the hose.

How to select a high-performance crack seal machine — 4 key factors

• Heat transfer oil indirect heating system: Prefer indirect thermal oil jacketing with a reliable burner (for uniform heating and to avoid scorching sealant).
• Electrically heated constant-temperature hose: Choose 5–7 m heated hoses with a Teflon inner lining and integrated sealing tips to prevent blockages and maintain flow.
• Smart two-way agitation system: A kettle with 360° vertical hydraulic or electric bidirectional agitation reduces melt time (30–45 min) and prevents bottom buildup.
• Reliable engine and reversible material pump: Use trusted engine/generator brands and a material pump with variable speed and reverse pumping to clear hoses after work.

Real client case (summary)

• Client profile: Road maintenance contractor working on interstate highways.
• Problem: Older low-end machine clogged frequently and took >1.5 hours to melt material, limiting output to under 800 m/day.
• Solution supplied: A YG-200L towable crack seal machine configured with an Italian Riello burner, a Honda engine, and a 5 m heated hose.
• Results: Heating time reduced to ~35 minutes; smooth flow and reverse pumping enabled >2,200 m/day, improving operational efficiency by ~40%.
