What are the performance advantages of the pavement joint filling machine itself? When should the small-sized joint filling machine be used to fill the joint?
As one of the important road maintenance equipment, pavement joint filling machine and asphalt cement consolidation machine can effectively reduce the maintenance pressure of road maintenance department. Advanced technology, convenient operation, high engineering quality and reasonable shortening.
Pavement joint filling machine and asphalt filling machine are the core equipment of filling technology. After the crack cracking and cleaning process, the crack is heated, and the sealant is evenly injected into the tank through the filling gun to complete the joint filling operation. When using asphalt filling machine, it is usually used with slotting machine or blower. When the asphalt paver carries out maintenance work on the asphalt pavement, removes luggage and waves, repairs winter and temporarily repairs damage, cold, spring rain and pavement quality used, high temperature is the first choice.
1. Heat transfer oil circulation is used to indirectly heat asphalt rubber to prevent burning and discoloration of asphalt rubber. Moreover, the filling effect of pavement becomes more beautiful.
2. The asphalt filling machine adopts electronic ignition system, automatic heating, temperature control, energy saving and time saving, which ensures the long-term operation of asphalt filling machine.
3. The discharge pipe of asphalt filling machine adopts electric heating, which is not blocked, has good quality and is not easy to be damaged. The effect of repairing pavement cracks is ideal.
The heating method of diesel burner is used to make the heat transfer oil circulate quickly and melt the asphalt slurry. The pressure of asphalt pump is discharged from the outlet, and the effect of crack treatment is proved. The material adheres to the wall of the coal seam.
Road filling is more important when using small-scale joint filling machine. At this point, you must master the best fill time.
In order to obtain the best effect and better protect the pavement, the cracks must be sealed immediately after they are formed.
In fact, most car owners begin to consider building joints after a certain number of cracks appear on the road.
When the crack width reaches 3 mm, it is recommended to start the filling process.
The best season is spring or summer. According to our experience, we must change the old idea of building roads in winter. Spring and summer maintenance activities take longer to complete.
Last fall, we used road filling machines and imported potting materials to fill urban roads. The length of the joint is about 30000 meters. After two temperature difference tests in winter and summer, it is proved that the sealing effect of cracks is good and water can not penetrate into the base.
