Management system designing of bridge´s maintenance costs

The primary goal of paper is to evaluate bridge management system in reducing maintenance and repair costs and studying impact of these systems on the structure´s life cycle. The paper a combination of management, engineering and economy has been proposed that: 1) increase safe traffics in roads network. 2) the extension of infrastructure life cycle using high benefit cost ratio maintenance programs 3)improvement of bridge condition by supplying decision makers with a specific tool for analysis of condition status and prediction of remedy needed. The paper addresses issues regarding with maintenance and repair policies and decisions for replaced bridge elements that from studies of previous experiences and interviewing with structural engineers in different companies. Bridge companies throughout the country will benefit from results of this research by comparing different maintenance methods. Findings show that using the proposed bridge management system has high influence on reducing the maintenance costs and increasing life cycle. However, it has also been revealed that, in special conditions, using engineers´ experience and decision-making capabilities has high impact on solving problems of bridge maintenance. Although using bridge management system for deciding of bridge maintenance and repair is very important, few researches have been performed in this topic.
