| Research Abstract |
In this study, deterioration assessment of weathering steel bridges constructed in different environment are investigated by employing the Atmospheric Corrosion Monitoring (ACM) sensor, Thermo-Hygro Meter (THM) and Surface Salt Meter (SSM). Moreover the surface roughness of weathering steel bridges is quantitatively evaluated by using Three-Dimensional photography measurement. The correlation of corrosion environment and rust state of weathering steel bridges is also clarified in this study.
