Developing a National Database System for Maintenance Actions on Highway Bridges

项目名称：	Developing a National Database System for Maintenance Actions on Highway Bridges
摘要：	A variety of maintenance actions are performed by highway agencies to preserve highway bridges. Although similar maintenance actions are applied, applications methods, rates, bases of measurement, costs, performance, and other related factors differ among these agencies. There is no widely accepted system for uniformly recording data pertaining to maintenance actions. Research is needed to review relevant information; recommend uniform definitions of the data associated with maintenance actions, and develop a database system for collection, storage, and retrieval of related data. These definitions and the database system will ensure proper interpretation of the data, facilitate their use by highway agencies in evaluating cost and performance of alternative maintenance applications, and provide a basis for cost-benefit analysis and evaluation of cost and deterioration models. These products will provide for maximum sharing and use of bridge-maintenance data and will help highway agencies make appropriate adjustments to improve performance or reduce cost of maintenance actions, thereby effectively managing bridge-maintenance resources and achieving the best possible value for the public dollar. The objective of this research was to develop a national database system of bridge-maintenance actions, materials, and methods, and their effectiveness to provide a means for establishing a record of actions that includes uniform descriptions of maintenance activities, bases of measurement, costs, impacts, performance, and other relevant data for use in cost-benefit analysis, selection of maintenance actions, or other related decisions. It was envisioned that the database system will be made adaptable for web-based application in a future project.
