When any kind of material in the paver is used up, the control switches for all material delivery should be turned off immediately, so that the mixture in the mixing drum is stirred and sent to the paving box after the paving is completed, the paver stops moving forward. Lift the paving box, move the paver out of the paving site, and clean the paving box. The construction staff immediately wiped out the remaining paving materials, put the wiped out waste materials into bags and moved them to the site.
After the paving is finished, straighten the horizontal joints to prepare for the docking when getting off the car. When getting off the car, spread a thin iron sheet of 1-2 meters wide at the horizontal joints and park the paving box on the iron sheet. , Begin to spit the material to ensure the straightness and beauty of the horizontal seams, and then remove the thinner on the iron sheet and pack it into bags. In the daily construction, the laboratory should do a good job in advance to determine the moisture content of the mixture, the screening of the mixture, and notify the unit in time to adjust the paving vehicle.
After completing one working day, count the daily mixture consumption, asphalt consumption, and calculate the oil-stone ratio. During the paving process, the construction unit and supervisor shall check the paving consistency and thickness of the mixture at any time. The consistency is based on experience. When checking the thickness, use a steel ruler to insert the inspection. The thickness of the slurry paving is not less than 6 mm. Through actual random inspection, more than 90% of the thickness is above 10 mm.
After paving, observe the forming condition of the slurry mixture according to the cohesion data and initial setting time measured in the laboratory, and use a rubber roller roller to roll it, but the roller must not turn or twist on the road surface of the slurry mixture When moving, the construction section at the micro-surface must be opened, and after the adjustment is completed, back or forward rolling.
In the initial maintenance, it is strictly forbidden to cut pedestrians and vehicles. When the paving time exceeds 2 hours, the traffic can be released.
Adding a micro-surface layer on the cement concrete pavement improves driving comfort and improves the appearance of the pavement. After driving and rolling in recent years, only a few micro-surface layers of less than 5 square meters were peeled off within 5 kilometers. Practice has proved that the micro-surface layer and cement concrete pavement bond well.
In the process of micro-surface construction, due to the rich construction experience of the construction unit, the supervision strictly controls the materials and thickness to ensure the quality of the project. It is especially important that no vehicles should be crushed within 2 hours of the paved micro-surface layer. As the traffic control of the owner's road administrators is in place, achieving this is the key to ensuring quality.
