Asphalt Crack Sealing Machine Functions
Asphalt crack sealing machine is becoming the fundamental pavement road cracks repairing equipment for road crack filling, bitumen crack filling, pothole repairing currently. Road cracks are caused by a combination of heavy traffic loads, environmental stress, aging, and underlying foundation issues. Obviously, without daily proper maintenance working, pavement conditions is getting worse gradually as time passes. So, bitumen crack sealant filler machine plays crucial role in irregular cracks maintenance of highway, city road, municipal road, urban road, airport runway and bridge expansion joints etc.
Asphalt Crack Sealing Machine Main Parts
1. Diesel engine Set/Gasoline engine Set
In an asphalt crack sealing machine, the diesel engine/gasoline engine acts as the primary power plant. The diesel engine/gasoline engine drives the onboard hydraulic system, runs the material agitator, powers the material pump, and runs an electrical generator to operate heated hoses and control panels.
2. Asphalt Melting Kettle
The asphalt melting tank serves as a primary component of the crack-sealing machine. Asphalt melting kettle is equipped with a safety device valve full cycle with a double layers thermal oil jacket 100 liters hot melt kettle that ensure heating faster and more uniform. Internally, asphalt melting kettle features a paddle-type forced agitator and a grid-patterned thermal conduction coil to ensure that the asphalt material is heated uniformly.
3. Electric Transfer Heating Tube
The electric transfer heating tube (or heated hose) is a crucial component that maintains the sealant’s optimal application temperature from the asphalt melter tank all the way to the pavement crack joints. It prevents the hot-pour rubberized asphalt from solidifying or cooling in the hose.
4. Riello Diesel Burner
The Riello diesel burner in an asphalt crack sealing machine acts as the primary heat source required to melt solid blocks of crack sealant into a liquid state and keep it at the precise application temperature. The asphalt crack sealing machine diesel burner safely and evenly melts solid rubberized crack sealant without scorching it. The burner heats the machine’s heat-transfer oil (or jacket), which then indirectly melts the asphalt material for application.
5. Variable speed mixing motor
A variable speed mixing motor on an asphalt crack sealing machine is essential for controlling the consistency, temperature, and application efficiency of the hot-pour sealant. It prevents material burning, ensures uniform blending of rubberized blocks, and accommodates different sealant viscosities.
6. Variable speed output motor
In an asphalt crack sealing machine, a variable speed output motor controls the pump that dispenses the heated rubberized sealant. It allows operators to dynamically adjust the flow rate to perfectly match the width and depth of the crack, minimizing material waste and ensuring a clean, precise sealing.
Asphalt Crack Sealing Preparation
Since common road cracks typically manifest in transverse and longitudinal patterns—and because the structural design of a crack-sealing machine’s application gun does not always align perfectly with the specific contours of these cracks during repairs.
1.Before crack sealing working, it is necessary to first use a grooving machine to recut the cracks. This process ensures that the shape and size of the cracks meet the requirements for sealing or filling, ultimately enhancing the effectiveness and durability of the repairs.
2.A road blower is necessary to clear away the debris resulting from grooving process inevitably generates dust. Road blower machine serves as a pre-treatment tool by cleaning the cracks and creating a suitable surface for improved adhesion of sealant or filling materials.
