What is a one-time paving method?
The one-time paving molding method means that the plastic mixture is directly formed by mixing and spreading E→Yansa rubber particles during construction. Without any modification, this is the most common method currently used.
Its specific operation method is to put the plastic raw materials into the machine after the mixing ratio, mix it evenly, transport it to the site, spread it directly on the grassroots level, level it with a screed, and at the same time wipe it out with a flat wipe. Make appropriate repairs, all actions are completed before the initial setting of plastic, so continue to paving, continue to repair. Because of the large temperature of the construction site, it is necessary to grasp the initial setting time of the plastic. Normally, you can use the index finger of the right hand to gently pull on the plastic surface. When the plastic surface is drawn at 9-l0cm, you can spread the surface layer of rubber. The surface layer of rubber should be uniform and the height of the sprinkle should not be too high, nor too low. Generally, 50-l00cm away from the surface layer. After 24h, the plastic surface layer can reach the final condensation before removing the unbound glue particles on the surface. . I
It takes about 24-36 hours for paving plastics to clean up rubber particles. During this period of time, the plastic surface layer absolutely prohibits walking on the upper body and prevents the animals from running up and down at night. The construction unit must set up personnel to protect the site.
What is a multi-layer paving method?
The multi-layer paving molding method is an improvement on the basis of the one-time paving molding method. Currently, most construction units use this method.
This method of operation, there are several layers of practice. The first is the screeding layer. This is on the spot. For uneven areas, make a layer of dressing, spread a small amount of plastic, flatten; the second is a large area paving, paving thickness of 70% of the total thickness, plastic Contains black colloidal particles. After the final coagulation of the plastic, the whole site is watered. Check the areas where there is stagnant water. Make a mark. After the water is dried, mix the liquid with plastic, and then make a leveling treatment. The third is a large-area paving. The initial setting time of the plastic and the Yansa surface layer of colored rubber particles waited for 24 to 36 hours after the plastic surface was finally coagulated, and then the unbonded colored rubber particles were recovered. This method is also called two-splitting, one-splitting, or two-two.
