PURPOSE:To form an uneven pattern for blind person even on existing paved road without erasing by a method in which a paint is applied to the upside of a formwork having hollows with holed tops, set on a paved road, and after the paint is hardened, the formwork is removed. CONSTITUTION:A plastic (polyethylene foam body 2 for example) formwork 1 having many recessions 3 whose tops are opened 4 is bonded to a paved road 8 whose base is conditioned by removing its release paper 6, and a paint 9 is applied to the upside of the formwork 1 to fill the recessions 3 with it. Before the paint 9 is completely hardened, a cover 7 is removed and after the paint 9 is completely hardened, the formwork body 2 is removed. The paint 9 may contain a metal powder which sounds when the stick of a blind person passes on it. The construction and repairing work can thus be simplified even on exising paved road and the removal of the uneven pattern can also be prevented. |
