A STUDY ON CORROSION RATING PROCESS FOR THE WEATHERING STEEL BRIDGES WITH SUPPLEMENTAL RUST CONTROLLING SURFACE TREATMENT

Abstract

In recent years, structures made of weathering steel has been paid attention concerning the life cycle cost. Minimizing the maintenance of steel bridges, it is important to accurately evaluate corrosion environment and rust condition. However, regardless of the experience in the corrosion rating, it is difficult for most civil engineers to evaluate the rust by the fixed level.
This paper proposed the new corrosion rating process for the weathering steel bridges with supplemental rust controlling surface treatment. The applicability and the future issues are discussed from the result of proposed rating process trial.
