The Working Principle of Asphalt Crack Filler Machine
Small asphalt crack filler machine adopts the liquid gas heating system and heat conduction oil circulation, which can melt the asphalt and potting sealant quickly and the asphalt pump achieves the effect of repairing cracks by the pressure of the asphalt pump being discharged from the discharge port. Then through the pressure injection type of filling, the material and the seam wall will be combined tightly. Next, the flexible universal wheel can track the cracks to make the filling joints more beautiful.
The asphalt crack filler machine is supplied with electricity by a gasoline generator which is very convenient and saves power. In addition, the pouring joint material uses asphalt and pouring joint glue which is easy to solidify when the temperature is low, so the machine uses the thermoplastic control system in the discharge pipe to avoid the machine burning and aging and ensure a smooth discharge at the same time.
The 10 Features of Small Asphalt Crack Filler Machine in YG:
Hand Push, independent power, light, practical, and reliable.
Be equipped with a traction burner, which can make it more convenient to walk, more labor-saving, and higher efficiency.
Adopt the most advanced technology, which improves the quality of the pouring joint and reduces the cost.
The whole machine is equipped with a generator set that can provide sufficient power.
Advanced intelligent ignition, detection, and temperature control system.
The unique design of the oil jacket hot melt kettle.
Design of heat cycle heating system.

The discharge pipe adopts an electric heating system, which effectively eliminates the condensation problem of filling joint material in the hose and reduces the manual cleaning of the hose.
Main Composition of Asphalt Crack Filler Repair Machine
Asphalt Hot Melt Tank. It is the most important component of asphalt seal coating equipment, which can provide asphalt with the required temperature. There is an impeller-type forced agitator and grid-type heat conduction coil to ensure the uniform heating of asphalt materials. The heat conduction oil is indirectly heated by a small gas-fired heating furnace, and the temperature can be automatically adjusted. In order to ensure the asphalt melts rapidly and uniformly, operators can start the stirring machine when the temperature of asphalt materials reaches 80 to 100 degrees.
Asphalt spray gun. Under the action of the asphalt pump, hot asphalt is poured into the joint by an asphalt spray gun. The device is made into a double-pipe circulation loop to improve the bonding effect. With iron at the nozzle, it can limit the asphalt ejected from the nozzle to the ironing range to prevent the spread of asphalt. And the asphalt that gushed but didn’t pour into the crack will be returned to the bituminous hot melt tank by loop pipe. Thus, the hot asphalt in the joint is well-bonded with the preheated joint wall. Meanwhile, because of the role of iron, the seams are flat and clean.
Ignition heating system. It usually has two thermostats, one can regulate the temperature of the heat-conducting oil and the other can regulate the temperature of the asphalt. When both regulators are adjusted, the burner flame remains constant.
Hydraulic drive system. It mainly provides power for the asphalt agitator drive motor, asphalt pump drive motor, and thermal oil transfer cycle drive motor.
How to Repair Asphalt Cracks
Before carrying out the crack-filling construction, road maintenance personnel need to check the width of the crack needed to be repaired and see if the seam needs to be widened. If the crack is too small, it should be extended to the appropriate depth and width of the construction joints.
Clean the cracks and then repair them with asphalt seal coating equipment. After pouring the cracks, spread the preheated stone chips on the cracks evenly, so as to complete the work of repairing asphalt cracks.
