| Abstrait: |
Deicing salts have spread in a large amount and more frequently after the prohibition on the usage of spiked tires. There is some damage in steel bridges due to spreading of deicing salts. Adhesion of deicing salts to girder is divided into two types. The first one is the water leak including deicing salts. The second one is scattering of deicing salts by wind and traffic passage. Steel is rapidly corroded by water leak. However, it is not evident that there is an adverse effect of scattered deicing salts in steel bridges. Therefore, in this paper, the relation between the adhered salts and corrosion of test pieces made of weathering steel is observed. Also, the applicability of weathering steel to cold and snowy districts is discussed. |
