How does the slurry sealing truck perform construction?
Release Time:2024-01-25
1. Various tests of raw materials must be carried out before construction of the slurry sealing truck, and it can be used only after passing the inspection. It is necessary to conduct various experiments on the mixture before construction. Only when it is confirmed that the material has not changed can it be used. During construction, according to changes in the residual content of the emulsified asphalt and the moisture content of the mineral material, it is necessary to adjust the cooperation ratio in time to make it meet the specified requirements, ensure the workability of the slurry mixture, and proceed with the construction.
2. On-site mixing: During construction and production, a sealing truck should be used for on-site mixing. The metering equipment of the sealing truck and on-site operation by a robot ensure that emulsified asphalt, water, mineral materials, fillers, etc. can be mixed in a certain proportion. , mixed through the mixing box. Because the slurry mixture has the characteristics of rapid demulsification, the operator must control the construction consistency to ensure uniform mixing of the mixture and workability of construction.

3. On-site paving: Determine the number of paving widths according to the road width and paving width, and start paving according to the driving direction. During paving, the manipulator starts operating as needed to make the mixture flow into the paving trough. When there is 1/3 of the mixture in the paving trough, it sends a starting signal to the driver. The sealing truck should travel at a constant speed, about 20 meters per minute, to ensure uniform paving thickness. After each vehicle is paved, the paving trough must be tidied up in time and the rubber scraper behind the paving trough must be sprayed and scraped. Keep the paving trough clean.
4. Inspection of the cooperation ratio during construction: Under the calibrated dosage unit, after the slurry mixture is spread, what is the oil-stone ratio? On the one hand, it can be checked based on experience; on the other hand, it is to actually check the dosage and spreading of the hopper and emulsion tank. Calculate the oil stone ratio and displacement from the time it takes to lay, and check the former. If there is an error, make further inquiries.
5. Do a good job in early maintenance and open to traffic in a timely manner. After the slurry seal is laid and before it solidifies, all vehicles and pedestrians should be prohibited from passing. A dedicated person should be assigned to do early maintenance to avoid damage to the road surface. If the traffic is not closed, When partial disease occurs due to tight or incomplete road surface preparation, it should be repaired immediately with slurry to avoid the spread of the disease. When the adhesion force of the mixture reaches, the initial maintenance is completed and vehicles can drive on it without obvious traces, and traffic can be opened.
