Performance Evaluation of Reinforced Concrete Box Culverts

The main objectives of this project are to: (1) Collect data from field testing of up to 10 reinforced concrete box culverts to evaluate their performance under a known truck load. (2) Evaluate live load performance, culvert capacity, and load rating using refined methods of numerical analysis validated with field test data. (3) Calculate a refined load rating for approximately 20-30 additional culverts based on the field data and numerical analysis results to assess the impact of different culvert attributes using statistical analysis. This will allow for extrapolation of the performance trends to the larger inventory of in-service culverts. (4) Develop a load rating decision matrix based on culvert size, soil fill depth, and other pertinent attributes to guide implementation of load rating calculations for MnDOT’s reinforced concrete box culvert inventory.
