At a general basis I think cracks abowe 0.2 mm in width should be repaired, both of structural and estetical reasons. The structural reasons is unsertain: I'v read reports (sorry, I do not remember titles or names) that concludes that cracs ar dangerous to some sytems and field reports that says teh opposite. Last week I talked with Mr. R. Kompen - concrete division of the Norwegian Road Dept. He told me that on some bridges that is exposed to high Cl- enviroment there was no sign that vertical cracks had more or deeper Cl-l consentratin then the uncracked parts of the bridge. For the time beeing I think it is best to be conservative. The specs for bridges ordered by the Norwegian road Detp. is using 0.2-0.3 mm as critical crack width. Cracks of this size will also be visible at a short range. oes ______________________________________________________________________________ Mr. Øyvind Sæter (Alternative: OEyvind Saeter) M.
