The work to be done in the pavement construction of pavement permeable bricks should include at least the following points:
Mixing of the mix Because the mix of the mix is generally an off-site gathering operation, the lime content must be controlled during the mixing process. Because the amount of lime has a great influence on the quality of the roadbed and the strength of the roadbed, The subgrade laid with permeable bricks should be treated with 6% limestone and suspended for disposal, and the water volume should be reasonably controlled. The water content during the daytime construction should be one to two percentage points higher than the normal water content to ensure timely supplement Water loss due to transportation, etc.
Paving Paving tasks must first ensure that the grassroots of the sidewalk is wet and can be stopped by watering the foundation.
When machinery is required for the construction industry, manual repairs must be coordinated with the construction.
In order to ensure that the design of the sidewalk is arranged in accordance with the design drawings, the results such as the thickness of the loose paving must be monitored in real time.
Rolling and leveling When the paving length exceeds a certain area and the moisture content of the mixture reaches a normal value, one-sided rolling of the structural layer should be stopped immediately.
The roller is used to stop the static pressure on the road surface in the form of uniform speed, and then the vibratory roller is used to stop the constant speed weak vibration and then to stop the strong vibration rolling. The static pressure of the smooth roller is used to end.
