Expertly undertake school pedestrian walkway construction with non-standing water and permeable pavement, as well as supply of pavement materials.

b. Fabric: Consider compaction预留height when laying permeable paving. When applying fabric manually to permeable paving, use a shovel to reverse the action; throwing is strictly prohibited. If the paving time exceeds 30 minutes or during strong wind conditions, cover the concrete site with plastic sheeting promptly to prevent excessive moisture loss from the permeable paving.

d. Surface Finishing: Promptly finish the edges of the compacted road surface with permeable concrete. For areas with insufficient material, fill and level the surface. For drier sections, spray a uniform layer of water first, then add material for finishing.

f. Maintenance: After the surface of the permeable pavement is finished, it should be immediately lightly watered and covered with plastic film for maintenance. The maintenance period is the same as that of normal concrete. During the maintenance period, barriers should be set around the road surface, and it is strictly forbidden for people and vehicles to enter.
