Abstract:Pressed by increases in construction costs coupled with insufficient funding for maintenance and new construction, many state and federal agencies are now specifying a service life of 75 years for all concrete bridges without significant repairs. In order to achieve this longer service life, better materials are required. MMFX Microcomposite Steel is a proprietary alloy that the company claims has greater corrosion resistance and structural properties which can achieve a service life of up to 75 years. This report summarizes previous research and the Utah Department of Transportation's experience with the use of MMFX Microcomposite Steel as deck reinforcement.
