PURPOSE:To provide a noise reduction road sign having durability with excellent legibility in the night time or less noise pollution by spreading specific paints on a road in the shape of a projective semi-spherical body with specific size or projective unfixed form at indefinite intervals within a certain width to solidify, and carrying out work linearly in succession. CONSTITUTION:A projective semi-spherical body with 1-50mm in diameter and size and 2-10mm in height or projective unfixed form is spread on a road A with various kinds of paints 1 at indefinite intervals within a certain width to solidify. At that time, the paints 1 are a molten type using petroleum resin or rosin ester resin as a bonding agent or a non-solvent using acryl, epoxy, polyester, urethane as main ingredients or a reaction hardening type. The paints 1 are also a water soluble type using various kinds of resin such as alkyd, acryl, epoxy, etc., as main ingredients or an emulsion type. Glass beads are provided to the surface or inside of the projective semi-spherical body or projective unfixed form 2, and the paints are spread and are solidified to carry out work linearly in succession. |
