Technology on the Corrosion Prevention and Maintenance of Steel Bridge

Abstract

In this thesis, the present condition and problems about painting of steel bridges, which consist of construction technology and maintenance technology, are described. In order to extend the life cycle of painting, our Institute has been carrying out various researches, such as the develoment of “the diagnosis system for the deterioration of paint films”, the developments of new paint systems by conducting the exposure test of painted specimens, the development of accelerated corrosion test method, the pilot work of field painting work, the development of the evaluation method of workmanship of the cleaning and so on. The outlines of these researches are also described.
