    Evaluation of surface modification methods to mitigate rusting and pitting in weathering steel bridges : final report.
    Raman, A.
    1986-09-01 | PDF
    Accelerated laboratory atmospheric exposure simulation tests with an acceleration factor of 50 and extending for a maximum of 2200 wet-dry cycles (6-year exposure equivalent) gave corrosion loss data that agreed fairly well with the field data derived from field coupons. The tests corresponding to sheltered location exposure showed that the rusting ...
