• Abstract:
  MDOT engineers calculate bridge load ratings using a list of representative vehicle configurations on Michigan roadways. Since the list was developed in the 1970s, bridge engineers were concerned it was outdated and they wanted to verify the accuracy of bridge load rating results. Using weigh-in-motion (WIM) data from sites across the state, researchers determined the characteristics of Michigan’s current freight traffic. From this data, they calculated actual vehicle load effects and recommended rating procedures to account for modern vehicle configurations, which will allow bridges to be rated consistently and accurately.
