Component

Every second, millions of Americans depend on a vast U.S. infrastructure that extends from coast to coast and is exceeding its design life. Concrete is a principal component of many transportation structures. While highly durable, a variety of processes degrade and damage concrete. Replacement is expensive and many cases warrant repair instead of replacement. Since many damage processes are progressive, early and properly timed repairs can reduce costs. An overall lifetime cost of ownership approach to selection and design of repairs has merit, but requires good information about costs and outcomes. There is a possibility that effective timing and application of repairs can be of great benefit to maintenance activities – including calculating lifetime costs and identifying rapid techniques that allow for expedited designs of repairs and minimizing repair times. This paper presents the results of a project aimed at the challenge in implementing comprehensive repair and maintenance practices in a state DOT’s bridge inventory. Challenges arise from the number of available repair techniques and specialization of the repairs according to special conditions and the type of component. To mitigate this problem and arrive at the best solution, this paper reports on the assembly and development of an automated computer-based graphical user interface (GUI) tool. The tool incorporates an easily accessible database of cost-effective and rapid concrete repair techniques that a user can access using a simple menu-driven GUI. The Concrete Repair GUI software will allow the user to arrive to the most effective type of repair technique by properly identifying the concrete failure type and analyzing the damage to that particular structure.
