1. The bottom of the gravel

As with ordinary concrete road construction, gravel cushions must be prepared first. And water should be sprinkled before pouring to keep the sub-grade wet and the road surface smooth.

  1. Mixing and pouring

The mixing of permeable concrete should strictly control the water-cement ratio, and the water should be added in multiple times. First, the luminous stone, cement, and 50% of the water consumption are added to the forced mixer and mixed for the 30S. The reinforcing agent is added and mixed for the 40s. And finally, the remaining water is mixed for the 50s to discharge.

  1. Vibration, tamping, stirring, compaction and flattening

The initial setting time of permeable concrete is 2 hours. After mixing, paving should be carried out quickly, and expansion joints should be set. Spread luminous stone on the pavement after compaction, and then use a low-frequency plate vibrator to expose the glowing stone to the surface and blend it into the permeable concrete road smoothly

  1. Maintain finished roads

The recommended membrane curing time for permeable concrete is more than 15 days, and sprinkle water curing for more than seven days. Be careful not to directly impact the concrete surface with a high-pressure water gun. Finally, spray permeable concrete topcoat and prevent passage.
