Most bridge rehabilitation and reconstruction projects result from deterioration such as cracks, corrosion, and deformation. That’s why it’s important to have accurate data of these “service limit states”. Developed through the second Strategic Highway Research Program (SHRP2), the
Service Limit State Design for Bridges (R19B) toolkit offers a quantitative framework in which to assess service limit states more accurately. The toolkit provides actual performance data, component-based distress models, and specific guidance for common bridge elements. Improving service limit state design extends the service life of bridges and allows designers to select bridge components based on expected maintenance and difficulty of replacement.
