A crack filling machine is professional road maintenance machinery built to inject hot sealing material into cracks on asphalt and concrete pavement. It stops water and grit from seeping into the pavement base, slows down pavement deterioration and extends overall road service life. Also known as crack seal equipment, this machine melts solid crack filler inside a heated hopper and delivers fluid sealant via a controlled pumping system to complete precise crack sealing work on varied pavement types. YG develops three mature specifications, including YG-50L, YG-80L and YG-100L, covering small-scale spot repair and large-area continuous road maintenance needs. Every unit optimizes heating, stirring and feeding structure to fix common blocking troubles that trouble most ordinary machines on the market.

Working Principle of Crack Filling Machine
The whole working flow of the asphalt crack filling equipment follows five orderly steps after material loading, without complicated extra operations:
- Material heating and melting: The corresponding heating system raises the internal hopper temperature steadily to around 180°C, turning solid asphalt or crack seal glue into uniform flowing liquid; the built-in mixing mechanism keeps raw material heated evenly to avoid local scorch.
- On-site crack pre-treatment: Construction crew cleans crack interior debris before filling to ensure tight bonding between sealant and crack inner wall.
- Controlled pressure filling: A hydraulic or pump system pushes molten sealant through an insulated discharge tube; operators trace the crack route with a flexible handheld nozzle for neat filling.
- Surface leveling: Excess overflow filler gets trimmed to keep the pavement surface smooth after filling.
- Continuous heat preservation: Constant-temperature pipeline stops sealant from premature solidification inside the tube during intermittent work, guaranteeing unobstructed continuous feeding.
Crack Filling Machine 6 Application Fields
- Municipal urban road routine maintenance: Cover urban arterial asphalt roads, branch concrete streets and sidewalk expansion joint filling, handling transverse cracks, longitudinal cracks and irregular surface fissures generated by seasonal temperature variation and vehicle rolling wear.
- Highway and expressway auxiliary upkeep: Complete periodic crack repair on main lane, emergency parking strip and median strip pavement, preventing rainwater infiltration from corroding roadbed and triggering subsidence or pothole formation in later periods.
- Airport and large logistics park ground maintenance: Seal fine and medium cracks on airport apron, cargo storage yard hard pavement and container parking areas; these high-load pavements bear frequent heavy vehicle compression and require regular sealing protection.
- Residential and commercial complex supporting facilities: Repair cracks on community internal access roads, underground garage entrance ramps and shopping mall outdoor parking lots, matching scattered intermittent repair work arranged by property management teams.
- Rural township and country road renovation projects: Adapt rugged rural pavement with mixed asphalt and cement structure, fill fissures formed by geological settlement and long-term agricultural vehicle passage under a complicated outdoor environment.
- Scenic spot pedestrian pathway maintenance: Complete crack sealing on scenic area asphalt walkways and stone-asphalt mixed trails, keep pavement intact to guarantee visitor walking safety without large-area pavement excavation.
Why Choose YG Crack Filling Machine?
- Diversified reliable heating setup: YG-50L uses liquefied gas heating, YG-80L combines liquefied gas plus heat conduction oil circulation, while YG-100L asphalt crack filling equipment adopts imported Italian diesel burner with full oil cycle heating. Graded heating modes match different ambient temperature and construction duration demands.
- Optimized anti-blocking design: Prevalent ordinary devices easily get clogged at the pump chamber, pipeline joints and discharge nozzle, yet our whole machine adds constant-temperature heat tracing on the discharge hose and uniform stirring inside the hopper to prevent filler solidification and blockage, cutting unexpected site downtime largely.
- Tiered filling speed setting: Filling speed ranges from 10m/min for YG-50L up to 20m/min for YG-100L, letting operators adjust the outflow rate according to crack width and construction progress flexibly.
- Practical power supply configuration: YG50L and YG80L equip solar panel plus battery groups for off-grid outdoor work, and YG-100L asphalt crack sealer machine matches imported 2KW generator to sustain long-hour continuous operation away from a fixed power source.
- Convenient moving structure: Base push-type walking with brake device for YG-50L and YG-80L, and push-plus trailer structure for YG-100L with an extra 5m handheld feeding pipe, easily reaching confined and remote construction areas.
