Road cracks are a common problem. Water can enter these cracks. It then damages the base layer. This leads to expensive repairs. Timely crack sealing prevents this damage. It extends the road’s life significantly. YG Machinery understands road maintenance well. We design reliable equipment for this task. We offer a high quality crack seal machine for sale. This machine melts specialized sealant. It then fills the cracks effectively. The sealant bonds with the asphalt. It forms a waterproof barrier. This stops water from seeping in. Our machines come in three sizes. They are the YG-50L, YG-80L, and YG-100L. Each model suits different project scales. You can choose the one that fits your needs. Our equipment is easy to operate. It is also durable and efficient. Investing in our machine saves you time. It also reduces future maintenance costs.

The YG-50L is light and portable. The YG-80L offers pump feeding for better flow. The YG-100L is the most advanced option. It includes a hand-held tube for precision work. It also has an electric stirrer and a generator. Furthermore, its automatic temperature control ensures consistent results.
Working Principle of Crack Filling Equipment
This crack filling equipment uses a straightforward process. It melts solid sealant blocks into a liquid state. The liquid then flows into the cracks. Here is how it works step by step.
1.The Heating System
The machine heats the sealant to a high temperature. The YG-50L uses liquefied gas for this. The YG-80L also uses gas. However, it adds heat transfer oil. This oil distributes heat evenly. The YG-100L uses an Italian diesel burner. This burner is powerful and reliable. It heats the oil, which then warms the sealant. This indirect heating method prevents burning. Burnt sealant loses its adhesive properties. Therefore, this system maintains material quality.
2.The Agitator System
Mixing is essential during the melting process. The YG-50L and YG-80L require manual mixing. The operator stirs the material periodically. This ensures uniform temperature throughout the hopper. The YG-100L features an electric stirring system. This automates the mixing task. It saves labor and ensures consistent blending. As a result, the sealant remains homogenous and ready for use.
3.The Discharge System
Once melted, the machine must discharge the sealant. The YG-50L uses a self-flow method. Gravity pulls the liquid out through a nozzle. This works well for smaller jobs. The YG-80L uses an asphalt pump. The pump feeds the sealant out under pressure. This provides a more consistent flow rate. The YG-100L also uses a pump. Additionally, it comes with a 5-meter hand-held tube. This tube gives operators greater flexibility. They can reach cracks that are far from the machine.
How Does This Asphalt Crack Sealing Equipment Seal Cracks?
The sealing process involves several distinct stages. Each stage plays a critical role. Understanding this helps you achieve the best results. This asphalt crack sealing equipment works in the following way.
Step 1: Crack Preparation
Proper preparation is key. You must clean the crack first. Remove all dirt, debris, and vegetation. You may need an air compressor for this task. The surface should be dry and clean. This allows the sealant to bond well. Poor preparation often leads to early failure. Therefore, never skip this step.
Step 2: Heating and Melting
Next, you turn on the machine. It starts heating the sealant. The temperature typically reaches around 180°C. The machine monitors this temperature constantly. The YG-100L has an automatic system for this. It maintains the precise heat. This ensures the material reaches the ideal viscosity. The molten sealant is now ready for application.
Step 3: Filling the Crack
The operator now applies the sealant. They place the nozzle or hand-held tube over the crack. For the YG-50L, the sealant flows by itself. For the YG-100L, the pump pushes it through the tube. The operator moves the nozzle along the crack. They fill the void completely. It is better to slightly overfill the crack. This accounts for settling during cooling. The machine’s speed can reach up to 20 meters per minute. This makes the work highly efficient.
Step 4: Cooling and Curing
After application, the sealant needs time to cool. This usually takes a few minutes. The material shrinks slightly as it cools. It forms a tight seal with the crack walls. The sealant becomes flexible. It moves with the asphalt during temperature changes. This prevents new cracks from forming. The repair is now complete and durable.
Manual Crack Filling vs. Mechanical Crack Filling
Many people still use manual methods. They use a simple pour pot and a torch. This approach seems cheaper at first. However, it has many drawbacks. Mechanical filling with our equipment is superior. Let us compare the two methods.
1.Efficiency
Manual filling is very slow. A worker can only cover a small area per hour. It is also physically tiring. Mechanical filling is much faster. Our machines fill cracks at 10 to 20 meters per minute. This covers large areas quickly. Consequently, you finish projects earlier.
2.Quality and Consistency
Manual pouring produces uneven results. The temperature is hard to control. The sealant may overheat or remain too cool. This affects adhesion. Mechanical equipment offers precise temperature control. It ensures uniform material application. The sealant penetrates deeply and evenly. This creates a stronger, longer-lasting bond.
3.Safety
Manual methods involve direct open flames. This poses a burn risk to workers. It also increases the risk of fire. Mechanical machines have enclosed heating systems. They are safer to operate. They also have safety features like brakes and temperature alarms. Workers face fewer hazards.
4.Cost-Effectiveness
Manual labor is cheap initially. However, the repairs often fail quickly. You will need to redo the work often. This increases total material and labor costs. Mechanical sealing has a higher upfront cost. Yet, the repairs last many years. You save money on maintenance over time. The investment pays for itself rapidly. Therefore, mechanical sealing is the smarter choice.
