Recently, the spectacle of the civil engineering structure has come to be often requested. Especially, harmony on the spectacle with surroundings is requested about the civil engineering structure in the city. Therefore, Public Works Research Institute executed the development of the coating materials to improve the spectacle function of the elevated structure in the city and executed a joint research with Hanshin Express-Highway Corporation. “Spectacle function improvement manual of the elevated structure in the city by coating materials (idea)” was made as the result.
Moreover, the dirt of the structure with the car automotive exhaust gas etc. has come to often damage the spectacle. It is said that the decrease of the visual check due to dirt is a cause of an accident increase in the tunnel. Therefore, the coating materials and the dirt which did not become dirty easily as a spectacle maintenance technology advertised for the drop dirt coating materials in the official gazette, and a joint research was executed with 17 private companies. “Antifouling material use guideline (idea) for the civil engineering structure” was made as the result.
