Product Introduction
Hand-Pushed Asphalt Hot-Melt Crack Sealing Machine is a lightweight road crack maintenance device, primarily used for heating, melting, and applying hot-melt road crack sealant.
This equipment is widely used in overseas road maintenance markets, commonly applied in scenarios such as parking lot maintenance, community road repairs, municipal minor repairs, and crack repair on commercial premises. Compared with large trailer-mounted crack sealing machines, hand-pushed crack sealing machines are more compact and highly maneuverable, making them ideal for small construction teams, property management maintenance units, and road repair contractors.
The equipment typically features a push-type structure, equipped with a heating kettle, thermometer, discharge valve, crack-filling scraper nozzle, or crack-filling gun. It can heat thermoplastic crack filler to the construction-ready state and directly inject it into cracks, forming a continuous sealing layer to prevent rainwater from penetrating the base course and thereby delaying crack propagation.
Product Features
Compact Structure, Flexible Mobility
The equipment has a compact size, making it suitable for construction in space-constrained areas such as parking lots, residential community roads, sidewalks, and factory area roads.
Hot-melt application ensures excellent sealing performance
Can be used in conjunction with hot-melt road crack filler; after heating, the material exhibits excellent fluidity and can fully fill cracks.
Manual operation, easy to use
No large-scale traction equipment is required—construction can be carried out manually, making it suitable for small-area and scattered crack repair.
High Construction Efficiency
Continuous discharge is possible after heating, making it suitable for routine road maintenance and emergency repairs.
Wide Range of Applicable Materials
Suitable for hot-applied sealants such as hot-melt asphalt crack filler and rubberized asphalt sealant.
Low Maintenance Cost
The equipment has a relatively simple structure and is easy to maintain, making it suitable for long-term use by small- and medium-sized road maintenance teams.
Application Scope
- Asphalt Pavement Crack Repair
- Cement pavement crack sealing
- Parking Lot Crack Maintenance
- Residential community road maintenance
- Small-area municipal road repair
- Industrial Park Road Maintenance

Construction Method
1. Crack Cleaning
Before construction, dust, soil, debris, and loose particles inside the crack must be removed; if necessary, a hairdryer or hot air gun may be used for cleaning.
2. Hot-Pour Crack Sealant
Add the hot-melt road crack sealing adhesive into the equipment’s melting tank and heat it to a fluid state suitable for application.
3. Control Temperature
Maintain a stable material temperature during construction to avoid insufficient flow caused by excessively low temperatures, as well as material aging caused by excessively high temperatures.
3. Crack Injection
Push the equipment along the crack direction to evenly inject the melted crack-sealing adhesive into the crack.
5. Surface Finishing
Use a squeegee or discharge nozzle as needed to smooth the surface, ensuring seamless adhesion of the sealant to the pavement.
6. Cooling and Opening to Traffic
Traffic can be reopened once the material has cooled and solidified.
Product Advantages
Hand-pushed hot-melt asphalt crack sealing machine is especially suitable for small-area, decentralized road crack maintenance projects. Compared with large-scale crack sealing equipment, it offers advantages such as lower procurement cost, convenient transportation, simple operation, and low maintenance cost.
For parking lots, residential community roads, factory area roads, and municipal routine maintenance, this equipment enables rapid crack sealing construction, reducing rainwater infiltration into the base layer and delaying the development of distresses such as potholes, raveling, and reflective cracking.
