There are several causes. fatigue, the percussion from the exterior, the decline of capacity by circumstances, the crack occured in the interior, the carbonation and so on, that can shorten the span of life of concreted construction. First of all, the life of R·C construction can be predicted to understand the connection between appearance status index, fatigue life and used life. In this report, I think that the status evaluation found out by the outside investigation with timeworn R·C bridge can be utilized for deciding bridge``s life and danger with analysis of appearance status index, fatigue-life and used-life.
