Asphalt crack sealing machines are commonly known as asphalt crack fillers, pavement crack sealing machines, or asphalt crack repair machines. They are often simply referred to as crack sealing machines in the industry. Their core function is to accurately inject heated and melted asphalt sealant into cracks in asphalt pavements. Through the bonding and sealing action of the sealant, they prevent rainwater and air from eroding the road base, thus repairing cracks and extending the service life of the pavement. This is a core piece of equipment for the preventative maintenance of asphalt pavements. Unlike traditional manual crack-filling methods, this equipment emphasizes precision, efficiency, and sealing effectiveness, and can adapt to the repair needs of cracks of different widths and types while significantly reducing labor costs.
In the field of asphalt pavement maintenance for highways, municipal roads, and parking lots, cracks are one of the most common types of damage. If not treated promptly, rainwater and snowmelt can penetrate through the cracks to the road base, leading to pavement damage and collapse, significantly shortening the road’s service life and increasing maintenance costs. YG offers a full range of equipment, including crack sealing machines, pavement grooving machines, road marking machines, and concrete laser screeds, capable of accurately completing road construction or repair operations. As a professional manufacturer of new road construction and maintenance equipment, YG has successfully served numerous road projects worldwide with its reliable product quality and customized solutions.

Why Are More and More People Choosing YG Asphalt Crack Sealer Machines Instead of Manual Methods?
- Improved sealing quality and extended road lifespan: Precise crack-filling technology and stable sealant temperature control ensure tight adhesion between the sealant and the crack walls, creating a secure, gap-free seal that effectively prevents rainwater and air erosion. This can extend the road’s lifespan by 3-5 years and reduce subsequent major repair costs.
- Significantly improved work efficiency and shortened maintenance periods: The efficient pumping system and automated operation mode increase work efficiency by more than 10 times compared to traditional manual methods. This allows for rapid repair of large areas of road cracks, avoiding traffic disruptions caused by maintenance work, and is especially suitable for quick maintenance of busy roads such as municipal main roads and highways.
- Reduced overall maintenance costs: Automated operation reduces labor input; only 1-2 operators are needed per machine, reducing the number of workers required by 3-4 compared to traditional manual crack filling. The efficient and energy-saving design reduces energy consumption, and the high sealant utilization rate reduces material waste, resulting in an overall maintenance cost reduction of over 50%.
- Enhanced multi-scenario adaptability and expanded scope of work: Multiple models and nozzle designs can adapt to the crack repair needs of different scenarios, such as parking lots, highways, municipal roads, residential roads, and airport runways. The parking lot crack filler equipment is lightweight and flexible, making it particularly suitable for small areas and multiple corners.
- Simple and easy to use, lowering the barrier to entry: The intelligent control system and user-friendly design mean that no professional technicians are required; ordinary personnel can operate the machine proficiently after 1-2 days of training. Detailed operation manuals and video guides are also provided. The equipment has a low failure rate, reducing subsequent maintenance costs.

Working Principle of the YG Asphalt Crack Sealer Machine
- Preparation: Move the asphalt crack sealer machine to the work site. Check the condition of all equipment components (such as the material tank, pipelines, and crack sealing gun). Add an appropriate amount of asphalt sealant to the insulated material tank. Simultaneously, use cleaning tools (such as a blower and a wire brush) to remove debris, dust, and water from the cracks, ensuring the cracks are dry and clean.
- Equipment Preheating: Start the intelligent temperature control system and set the sealant melting temperature (usually 160-180℃). The system automatically heats the sealant in the material tank. The temperature sensor monitors the temperature in real time and feeds it back to the temperature controller. By adjusting the heating power, the temperature is stabilized within the set range. Once the sealant is completely melted and in a fluid state, start the stirring device to ensure even mixing.
- Precise Crack Sealing: Adjust the pouring flow rate according to the crack width. The operator moves the equipment or drives the vehicle-mounted equipment, aiming the crack sealing gun nozzle at the crack. Start the pumping system, and the molten sealant is injected into the crack at a constant speed under pressure. During the pouring process, ensure that the sealant fills the crack completely, without gaps or air bubbles. For wider cracks, multiple pouring passes may be used to ensure a tight seal.
- Surface Finishing: After pouring, use the equipment’s built-in leveling device or a manual scraper to level the excess sealant on the crack surface, ensuring the sealed surface is flush with the road surface, improving road smoothness and aesthetics. At the same time, promptly clean any remaining sealant from the crack sealing gun nozzle to prevent solidification and blockage.
- Curing and Maintenance: After completing work in one area, move the equipment to the next work location and repeat the above process. For areas where crack sealing has been completed, set up warning signs (such as cones and warning tape) to prohibit vehicles and pedestrians from driving or walking on the area. After the sealant has naturally cured (usually 1-2 hours, depending on the ambient temperature), remove the warning signs and restore normal road traffic.
