Enhance and Improve Rating Aids for the Evaluation of Existing Concrete Box/Slab Culverts

Approximately 44% of Tennessee bridges/highway structures (8,661 out of 19,616) are classified as culverts. The ages of existing culverts in Tennessee span a large range, with the oldest one built in 1905. Some of these culverts are currently in poor condition and need to be evaluated for their structural capacity. Furthermore, Federal Regulations require that all highway structures including culverts be load rated for their live load carrying capacity. Therefore it is essential that efficient tools be developed for culvert rating. During the TDOT Project 28012 – ED 1236527, Developing Rating Aids for the Evaluation of Existing Concrete Box/Slab Culverts in Tennessee, the Tennessee Tech University (TTU) research team has completed a number of milestones, including: the establishment of a culvert database; selection and verification of a culvert rating software; analysis of culvert models for load rating; initial screening of the rating results; and setting up a trial format for rating aids. The examination of the obtained rating results reveals that further refined analysis and research are necessary in order to have a better understanding of the results and have an in-depth study on certain loading responses, and, ultimately, to establish efficient culvert rating aids.
