[VI-133] Continuation investigation of application to non-destructive inspection in Okinawa, a subtropical island environment
Keywords:road attachments, non-destructive inspection, corrosion, ultrasound
With regard to road attachments, in Okinawa, which is a salt-damaged area, corrosion at the road surface boundary is a point that should be particularly watched, since corrosion at the road surface boundary may cause collapse during strong wind such as a typhoon. In this paper, we continued from last year and conducted nondestructive inspection on the attachments installed in Okinawa prefecture, which has characteristics of severe salt damage environment, and verified its effectiveness. As a result of verification, it has been confirmed that it is possible to grasp the situation of corrosion deterioration of road surface boundary part by nondestructive inspection.
