In-Depth Look: How Our Crack Filling Machine Works
Our road crack sealing machine is designed for high-efficiency, long-lasting road repair. It uses a hot-melt sealing technique to heat asphalt or specialized sealants to a liquid state. This material is then injected under pressure into the pavement cracks.
Key Features & Technical Advantages:
- Efficient Heating : Our system uses either LPG or a powerful diesel burner to heat heat transfer oil. This oil then transfers heat evenly to the sealing material. This indirect method ensures the material melts quickly without burning, preserving its integrity.
- Precision Injection : A high-pressure asphalt pump forces the molten material deep into the cracks. This creates a tight bond between the material and the crack walls, leading to a superior seal and a longer repair life.
- Flexible Operation : Our Walk-Behind Crack Sealing Machine features a flexible universal wheel design. This allows operators to easily follow irregular crack patterns for a precise and aesthetically pleasing result.
- Constant Temperature Control : The machine’s discharge hose has a constant temperature control system. This prevents the sealing material from solidifying and clogging the hose in colder temperatures, ensuring a smooth and uninterrupted flow.

Crack Filling Machine Q&A
The repair rate depends on factors like crack conditions and operator skill. Typically, a skilled crew using our machine can complete 2,000-3,000 meters of crack sealing per day.
Clogging is a common concern. Our crack filling machine has been designed to address this. With an optimized anti-clogging design in the melting pot and temperature control at the outlet, we significantly reduce the risk of blockages.

Diverse Applications & Success Stories
Our asphalt crack filler machine for sale is widely used on various surfaces, including highways, city streets, airport runways, and industrial pavements.
- Saudi Arabia, Municipal Road Project : This project faced severe cracking on asphalt roads. Traditional patching was ineffective and costly. By using our YG crack filling machine, they increased their daily efficiency by 40% and extended the repair life by at least two years. The project manager was highly impressed with the sealing efficiency and low maintenance cost of the asphalt crack repair machine.
- Australia, Airport Runway Maintenance : Runway cracks pose a serious threat to flight safety. Our crack filling machine was chosen for its precise pressure injection and efficient heating system. The smooth discharge feature allowed for continuous work, greatly reducing runway downtime and flight delays.
