Crack sealing equipment is a machine used to fix cracks in roads, highways, and parking lots. It seals a special material (like asphalt) into the cracks. This stops water, dirt, and other things from getting into the cracks and damaging the road further. There are different types, like an asphalt crack filler machine for narrow cracks and a traction road crack sealing machine for rough roads.

How Does Small Crack Sealing Equipment Work?
It’s easy to understand how crack sealing equipment works. Here are the simple steps.
1. First, the machine cleans the crack. It uses air or a brush to remove dirt and small stones.
2. Then, it heats the crack. This makes sure the sealing material sticks well.
3. Next, the machine pours the hot sealing material into the crack. The material is usually asphalt or a similar mix.
4. Finally, it smooths the surface so the road looks even. This process stops the crack from growing. It’s quick and works well for most road cracks.
Advantages of Traction Road Crack Sealing Equipment
The asphalt crack filler machine has many good points:
1. Saves money: Fixing small cracks early stops big, expensive repairs later.
2. Lasts long: The sealed cracks stay strong for years, even with cars driving over them.
3. Easy to use: Most machines are simple to operate, so workers learn fast.
4. Works in many places: It can fix cracks in asphalt, concrete, and other road materials. Using this equipment keeps roads safe and in good shape.
Case: Asphalt Crack Filler Machine Sold to the Czech Republic
A road maintenance company in the Czech Republic is troubled by its deteriorating local roads — the pavement is covered with numerous cracks, and infiltration of seasonal rain and snow only makes matters worse. They purchased our asphalt crack filler machine — Model YG-80L to fix this persistent problem.
What are the core strengths of this equipment? Unlike basic gravity-flow models, the YG-80L is fitted with an asphalt pumping feeding system to deliver consistent, steady material output. It uses liquefied gas heating together with thermal oil circulation heating to keep the sealant temperature even and controllable. Smart temperature control sensors maintain the material temperature steadily at 180°C, which stops high-temperature aging and avoids poor fluidity caused by low temperatures.
It delivers immediate construction results. Cracks get evenly filled at a speed of 15 meters per minute, forming a long-lasting sealing layer that effectively blocks rainwater seepage and stops cracks from widening further. The client shared feedback that the machine’s push-type design with brake units makes on-site movement and operation extremely easy. Its solar panel plus storage battery power supply eliminates the need for external power sources, a major advantage when working on remote road sections.
Within just a few weeks, the treated road surfaces look brand new — surface flatness is greatly improved, and driving safety is boosted significantly. The client also specially noted that the equipment is incredibly user-friendly. Workers can operate it after brief training, cutting labor costs and slashing long-term maintenance expenses by a large margin.
How to Choose the Right Crack Sealing Equipment?
1. Check crack width and maintenance workload
For narrow surface cracks and light maintenance work, the YG-50L is a reliable, cost-effective entry-level option. Its 50L tank uses gravity feeding, with a maximum filling speed of 10 meters per minute, more than enough for small repair jobs.
For medium-width or wider cracks, or heavy maintenance work, we recommend upgrading to YG-80L or YG-100L. The YG-80L comes with an asphalt pumping feeding system for smoother, more consistent material output. The YG-100L delivers the fastest filling speed at 20 meters per minute and includes a 5-meter handheld discharge hose, ideal for precise work.
2. Check mobility demands at construction sites
All three small crack filling machine for sale feature a push-type design with brakes, so one person can move them with ease. The YG-100L has an extra towing function that lets you hook it up to vehicles for long-distance transport, perfect for road maintenance crews visiting multiple job sites in one day.
3. Check climate conditions and heating requirements
YG-50L: Liquefied gas heating only, fit for occasional use in mild weather.
YG-80L: Upgraded liquefied gas plus thermal oil circulation heating for more even heat distribution, suitable for frequent operations.
YG-100L: Fitted with an imported Italian diesel burner and thermal oil circulation heating, plus an automatic temperature control system. It accurately holds the sealant’s optimal working temperature even in cold weather, making it the top pick for all-weather work.
4. Check power supply conditions at construction sites
If you often work on remote road sections with no external power access, the YG-50L and YG-80L are equipped with solar panels and storage batteries. They run fully off-grid with no reliance on mains electricity.
For long continuous construction hours or to skip manual stirring, the YG-100L carries an imported 2KW generator. It supplies steady power to the electric stirring system, eliminating manual mixing entirely and saving time and labor.
