Road excavation
According to the design requirements, excavate subgrade and remove earthwork to reach the design elevation; Check whether the longitudinal slope, transverse slope and sideline meet the design requirements; Trim subgrade, level and compact, and the compaction coefficient reaches above 95%. Pay attention to laying pipelines.
Base course laying
Pave graded sand with the thickness of 150~ 180mm (the particle size is not more than 60mm, and the particle size is not more than 0.5mm), level and compact, and the compactness will reach over 95%.
Leveling layer laying
The leveling layer is made of medium sand, 30mm thick, which requires a certain gradation, that is, graded sand with a particle size of 0.3-5mm for leveling.
Surface course laying
The surface layer is pavement brick. When laying, the pavement brick should be laid according to the design pattern. When laying, it should be laid flat gently and stabilized with a rubber hammer, but the corners of the brick should not be damaged. Then fill the brick hole with nutrient soil, replant grass and water conservation. The quality requirements meet the requirements of CJJ 79-98 Code for Construction and Acceptance of Interlocked Paving Brick Pavement.

Planting grass takes two steps. Fill in the base soil first, then sprinkle water on the soil to stabilize it, then sprinkle grass seeds, and finally sprinkle some soil to make the base soil equal to the top of the lawn grid. During the germination of grass seeds, be sure to water them frequently and don't drive on the newly planted turf. Once the turf is fully grown, the area can be put into use. Always look after the grass-planted pavement, mow the grass and fertilize it if necessary. Only in this way can we have a beautiful environment for planting grass for a long time.
