Improvement and Maintenance Technology of Spectacle Function of Civil Engineering Structure by Coating Materials

摘要

Recently, the spectacle of the civil engineeringstructure has come to be often requested. Especially, harmony onthe spectacle with surroundings is requested about the civilengineering structure in the city. Therefore, Public WorksResearch Institute executed the development of the coatingmaterials to improve the spectacle function of the elevatedstructure in the city and executed a joint research with HanshinExpress-Highway Corporation. "Spectacle function improvementmanual 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 automotiveexhaust gas etc. has come to often damage the spectacle. It is saidthat the decrease of the visual check due to dirt is a cause of anaccident increase in the tunnel. Therefore, the coating materialsand the dirt which did not become dirty easily as a spectaclemaintenance technology advertised for the drop dirt coatingmaterials in the official gazette, and a joint research was executedwith 17 private companies. "Antifouling material use guideline(idea) for the civil engineering structure" was made as the result.
