Further, by using the road surface molding auxiliary member 1, it is not necessary to provide a water gradient for drainage, so that it is possible to mold a horizontal road surface. As a result, the surface water is prevented from being drained in a predetermined place, so that environmental problems such as flooding of rivers are suppressed and the demand for leveling the road surface can be met. It will be possible.

The shape and size of the diameter of the second through hole 31 may be designed according to the situation. For example, in a place with many pedestrians, a second through hole 31 with a small diameter is formed so that a fallen portable object cannot pass through, and in a place with a small amount of water in the ground, a second through hole with a large diameter is formed. It is conceivable to form 31 and the like.

Further, in the present embodiment, the first through holes 23 are communicated with each other by the communication portion 24.
