EVALUATION OF BRIDGE COATING LIFE FOR THE DEVELOPMENT OF AN EXPRESSWAY ASSET MANAGEMENT SYSTEM

This paper describes how maintenance costs are skyrocketing. To control such high rising maintenance cost, the introduction of proper asset management is expected in order to prolongs the life of expressways by keeping their soundness and reliability. Considering the importance of Asset Management, Japan Highway Public Corporation (JH) studies the development of a logical frame of Asset Management systems and establishment of their practical implementation methods. This report introduces recent studies of JH's asset management, further, a steel bridge coating deterioration degree diagnosis system (here after "Paint View") is explained in detail among bridge management systems whose research and development go ahead of management systems for other type of assets. This Paint View is the system that makes objective as well as quantitative evaluation of coating deterioration using a computer image processing technology of steel bridge coating with images by digital cameras. As a result, life cycle cost is mentioned based on the evaluated deterioration curve and remaining life of coating. These evaluations are based on the analysis of overall steel bridges on nationwide expressways in Japan (about 2,400 bridges) that are obtained by statistical data processing and engineering analysis using the result of diagnosis by Paint View.
