Evaluation of Service Life Design of Bridges
Increasing the service life of bridges is a very high national infrastructure priority. In fact, a recent Strategic Highway Research Program (SHRP) project was specifically dedicated to developing tools for designing bridges to meet specifiable service-life design criteria. Specifically, it was intended to develop procedures, approaches and details that would ensure that bridges have service lives beyond 100 years. Iowa DOT is playing a lead role in the implementation of this SHRP project by actively demonstrating the integration of the recommendations in typical bridge replacement projects. Iowa DOT is currently involved in two projects to integrate the results of the SHRP project. One bridge project was designed using current practices, procedures and details with the other will be designed using service life design procedures. Because these two bridges will be exposed to the same environmental conditions, very similar traffic and will be constructed within the same timeframe, a unique opportunity exists to identify and evaluation differences in performance between the two bridges.
