How to improve the reliability of pavement joint filling machine
It is applicable to crack widening before filling and repairing of asphalt pavement. The equipment has the advantages of easy to use, fast expansion speed, long service life of blade and adjustable width of expansion joint, which is widely used in various asphalt pavement expansion operations.
Product advantages of road slotting machine
1. Unique dust removal system;
2. Simple adjustment of slotting depth;
3. The milling cutter is located between the fuselage and the wheel, which is convenient for observing the pavement cracks and adjusting the slotting direction;
4. The special shield can protect the transmitter and battery from dust;
5. Simple design of fuel tank makes it more convenient to refuel;
6. The powerful Honda engine is equipped with dust blowing and exhaust function, which can protect machinery and staff from slotting dust;
7. The protective device shall be set to avoid the influence of slotting dust and the engine can inhale fresh air
8. The generator of international famous brand can provide stable and efficient output for the whole machine, and work stably and reliably;
9. The humanized handle design of the joint filling gun handle, which is equipped with an electric control switch on the handle, can remotely control the asphalt pump to avoid waste, sanitation and cleanness;
10. High temperature professional asphalt pump, with high conveying pressure, material embedded in deep cracks, guaranteed construction quality, stepless adjustment of material flow, suitable for crack repair of various widths and shapes.
Pavement crack repair is to bond the cracks in the street with joint sealant. After bonding, it can not only protect the pavement from flooding in rainy season, but also extend the service life of the pavement, so as to prevent the pavement from boiling and damage.
The reporter saw at the scene that the maintenance personnel used the heating function of the joint filling machine to evenly "squeeze" the special asphalt material onto the polished cracks. The maintenance personnel also set up construction and maintenance warnings on the road surface to remind drivers to pay attention to driving safety.
During the maintenance and construction, the urban management personnel first planed and cleaned the cracks on the road surface with machinery, and then heated the materials on site by the mechanical operation vehicle filling the joints, and then paved and repaired the broken joints after planed and washed. Just like the "surgical suture" for the pavement, the asphalt material on the pavement after patching can be bonded after half an hour, and the strength will become stronger and stronger, and it is resistant to vehicle rolling and waterproof.
