The crack sealing machine integrates heating, mixing, grouting, and leveling functions. Their core function is to precisely inject hot materials such as asphalt sealant and polyurethane sealant into road cracks, achieving crack sealing and road structure repair. As the core equipment in crack sealing technology, it is generally used in conjunction with a grooving machine and a blower (or hot air gun) to complete the standardized construction process of “crack cleaning—preheating—crack sealing—leveling.” Contact us now for product details and the latest quote!

Crack Sealing Machine Classification
(I) Classification by Movement Method
- Hand-push Crack Sealing Machine: Pushed by a single person, lightweight, small turning radius, 100L-200L capacity, flexible in narrow sections of streets, alleys, residential areas, and parking lots; the largest purchase volume for small and medium-sized construction teams.
- Towed Crack Sealing Machine: Equipped with a trailer chassis and inertia brake, 200L-600L large capacity, towed by pickup trucks or tricycles, suitable for long-distance continuous construction, with strong endurance.
- Vehicle-Mounted Crack Filling Machine: The equipment is integrated into the chassis of a maintenance truck, equipped with a high-power diesel engine, fully automatic temperature control, and a remote control system. It can fill 800-1500 meters of cracks per hour, specifically designed for large-scale maintenance projects on highways and main roads, offering the highest level of automation.
(II) Classification by Heating Energy Source
- Liquefied Petroleum Gas (LPG) Heated Type: Low cost, quick start-up, low noise; primarily 100L-200L push-type models, the first choice for scattered municipal repairs.
- Diesel Thermal Oil Heated Type: High thermal efficiency, long operating range, not limited by gas cylinder capacity; standard configuration for large-capacity towing and vehicle-mounted models; highly adaptable to remote areas without refueling.
- Electric Heated Type: Clean and smokeless, precise temperature control; limited to fixed locations in factory areas, indoor floors, and charging station parks; requires an external three-phase power supply.
(III) Classification by Operating Pressure
- Pneumatic type: Simple structure, low cost, but generally stable discharge pressure;
- Hydraulic pump type: Constant pressure, dense filling, no voids, mid-to-high-end YG series all come standard with a hydraulic conveying system.
YG Crack Filling Machine Brand Core Competitive Advantages
YG has been deeply involved in road maintenance machinery for over ten years. Its entire product line has abandoned simple pneumatic structures, uniformly adopting a hydraulic pressurization + full-process heat transfer oil constant temperature system. It boasts imported equipment quality at a more affordable domestic price, offering clear differentiated advantages:
- Upgraded Temperature Control System: Dual independent temperature control (heat transfer oil and discharge hose temperature control separately), with a stable temperature difference of ±3℃, far exceeding the industry average of ±5℃. This prevents the filler adhesive from scorching or solidifying, doubling its service life.
- Thickened Wear-Resistant Capsule: The hot melt vessel uses an 8mm high-temperature resistant carbon steel lining, which is corrosion-resistant and deformation-resistant, increasing service life by 60% compared to ordinary 5mm capsule bodies.
- Hydraulic Pump Anti-Clogging Design: The pump body has a backflushing circuit, allowing for one-button reverse rotation to discharge residual adhesive during machine shutdown, significantly reducing pipe blockage failures and reducing wear on vulnerable parts by 40%.
- Multi-Scenario Power Options: The same volume model can switch between LPG/diesel dual heating systems, allowing customers to choose according to their needs, making one machine suitable for various working conditions in urban and field environments.
- Strong customization capabilities: Supports extended electric heating hoses, installation of integrated hot air seam cleaning machines, and modification of vehicle-mounted mounting brackets to meet special project customization needs.
- Energy saving and noise reduction optimization: The burner ensures complete combustion, resulting in 15% lower fuel and gas consumption compared to competitors. The generator set is tuned for quiet operation, meeting noise reduction compliance requirements in urban areas.
YG Crack Sealing Machine Application Scenarios
- Highways and National/Provincial Roads: Prioritize the YG350L tow-mounted and YG600L vehicle-mounted models for treating longitudinal and transverse cracks and settlement joints. This is crucial for areas with short working windows and high-continuous operation requirements. High-pressure grouting ensures the sealing strength of heavy-duty highways.
- Urban Main and Secondary Roads: The YG100L push-mounted model is the primary choice. For side streets and pedestrian walkways, the YG60L is used in conjunction. The quiet operation of this urban unit meets environmental control standards.
- Residential Communities, Industrial Parks, and Parking Lots: The YG100L provides sufficient coverage for repairing asphalt parking spaces, cement expansion joints, and fine cracks in non-motorized vehicle lanes.
- Bridges and Elevated Expansion Joints: All models are compatible. Use with modified high-viscosity crack sealant. YG hydraulic high-pressure grouting prevents water seepage and corrosion of bridge bearings after traffic has commenced.
- Airport Runways and Port Yards: The YG350L/600L large-capacity models are preferred for all-weather, high-intensity operation. They are resistant to oil stains and heavy truck traffic.
- Expansion joints in water conservancy dams and canals: Custom-designed anti-corrosion YG model, compatible with hydraulic engineering sealants, offering stable anti-seepage performance at low temperatures underwater.
Frequency Tests for Crack Filling Machines
Q1: Can the crack-filling machine only use asphalt crack-filling adhesive?
A: All YG models are compatible with hot-melt asphalt, modified asphalt, road-specific sealants, and hydraulic engineering sealants; the small electrically heated model can handle small amounts of room-temperature grouting materials, and the adjustable hydraulic pressure is suitable for fillers of different viscosities.
Q2: Can it be used normally in sub-zero winter temperatures?
A: Yes. The YG dual-circuit constant temperature system hose is fully insulated, ensuring stable material output even at -25℃. For low-temperature conditions, it is recommended to use a high-weather-resistant crack-filling adhesive, and preheat the joint walls with a hot air gun before application to improve adhesion.
Q3: Will the equipment leak oil or adhesive during transportation?
A: YG products come equipped with a sealing locking valve and a vessel sealing cover; the trailer has a built-in shock-absorbing chassis. During long-distance logistics, the colloid and heat transfer oil inside the vessel are emptied, and the vessel is reinforced and secured throughout the journey. Damaged parts will be replaced free of charge by the factory.
Choose YG, A Professional Crack Sealing Machine Manufacturer
YG, as a self-manufacturing and self-developed crack sealing machine factory, possesses three irreplaceable values:
- Technological Iteration Capability: With its own machining workshop and temperature-controlled laboratory, YG optimizes heating and hydraulic systems annually for different climates and new crack sealing adhesives. OEM manufacturers only assemble machines and lack this improvement capability.
- Controllable Life-Cycle Costs: YG mass-produces original factory-grade wear parts, resulting in parts prices 30% lower than those of trading companies. Its quality assurance system reaches the end user directly, eliminating middlemen and ensuring after-sales service.
- Project Solution Matching Capability: Pre-sales technical engineers can accurately match models based on the customer’s annual project volume, construction area, and transportation conditions, avoiding the waste of large equipment for small projects and the delays caused by using small equipment for large projects.
In short, from an industry trend perspective, the demand for road maintenance is expanding year by year. Low-cost preventative crack sealing is replacing large-area milling and resurfacing as the mainstream. A YG crack sealing machine adapted to the specific conditions can serve stably for 8-10 years, helping construction companies secure maintenance projects, reduce material and labor costs, and become a long-term profit-generating tool.
