You have a cracked road, a parking lot full of fissures, or an airport runway that needs maintenance. If you leave those cracks open, water seeps in, freezes, and turns a small line into a pothole. Fixing potholes costs ten times more than sealing cracks early.
A crack filling machine melts rubberized asphalt or crack sealant and injects it deep into the crack. It bonds tightly to the walls, seals out water, and lasts for years. YG Machinery offers three models: YG-50L, YG-80L, and YG-100L.
Filling speed ranges from 10 to 20 meters per minute. A skilled crew can seal 2000‑3000 meters per day.

How Does A Crack Filling Machine Work?
Step 1 – Prepare the crack. Use a slotting machine (crack router) to open the crack and a blower to remove dust and debris. Clean cracks mean better adhesion.
Step 2 – Melt the sealant. Pour solid asphalt or rubberized crack filler blocks into the hopper. Turn on the heating system. For YG-50L/80L, liquefied gas heats the material. For YG-100L, an Italian diesel burner circulates hot oil around the hopper. The material melts to a liquid at around 180°C. Pre‑melting takes 1‑2 hours per batch.
Step 3 – Apply the sealant. For YG-50L, gravity pulls the liquid out of a spout. You push the machine along the crack. For YG-80L and YG-100L, an asphalt pump pressurizes the material. The pressure injection forces sealant deep into the crack, bonding to the side walls. The YG-100L has a 5m hand‑held tube – you can walk along the crack while the machine stays parked.
Step 4 – Follow the crack. The YG machines have a swivel caster wheel that tracks the crack line. You do not have to steer constantly. The result is a neat, straight fill.
Step 5 – Keep it flowing. In cold weather, the sealant can thicken. The YG-100L has a constant temperature control system on the discharge tube. It prevents burning or clogging. The 2KW generator powers the electric stirrer and the hose heater.
A skilled crew can seal 2000‑3000 meters per day. Material consumption is 200‑300 kg per day, depending on crack width and depth.
Where Can You Use A Crack Sealing Machine?
- Highways and expressways – Routine maintenance to prevent potholes.
- Municipal roads – City streets with asphalt or concrete surfaces.
- Airports – Runway and taxiway crack sealing.
- Plazas and parking lots – Commercial and public parking areas.
- Industrial parks – Factory yards and access roads.
- Complex or irregular pavements – Cracks that are not straight, where precision matters.
The machine works on both asphalt and concrete pavements. For best results, always use a slotting machine and blower first.
Seal Cracks Early, Save Big Later
A crack filling machine is not expensive compared to the cost of pothole repair. YG offers three reliable models. The YG-50L is simple and solar‑powered – ideal for small jobs. The YG-80L adds a pump for better penetration. The YG-100L is the professional choice: diesel heating, electric stirring, 5m hand tube, trailer, and automatic temperature control. All models are easy to push or tow, with brakes for safety.
For highway crews, the YG-100L can seal 2000‑3000 meters per day. For a small crew, one machine pays for itself in a month of work. YG Machinery also offers slotting machines and blowers to complete the system. Contact YG with your typical crack size and daily meterage.

Frequently Asked Questions
Yes. The heating system keeps the material at 180°C. The YG-100L has a constant temperature control on the discharge tube to prevent clogging in cold weather.
For best results, yes. Slotting cleans and shapes the crack. Blowing removes dust so the sealant sticks.
It has a trailer with a brake device. Check your local regulations for towed equipment. The maximum towing speed is 30 kph according to the document.
Run hot sealant out until empty. Then use a cleaning agent or heat and scrape. The YG-100L has an anti‑clog design, but regular cleaning extends life.
1‑2 hours. Plan ahead. Start heating while you prepare the site.
