The primary objective of this project is to reduce the risk of structural failure of short-span culverts serving major highways in Ohio. This goal will be met by achieving the following two major components of the project - (1) detailed field inspection of shortspan culverts that were identified as critical structures in ODOT districts; and (2) validation of the culvert inspection and rating procedures presented in the ODOT Culvert Management Manual (ODOT 2003). Tasks of this project are divided into: Task 1: Obtain from each ODOT district an inventory list of high-priority short-span culvert structures. Convert the data into a spreadsheet format. Task 2: Review the FHWA's and other DOT's culvert inspection policies and procedures. Task 3: Perform field inspections of sixty short-span culverts in Ohio, including those that are considered as high-priority structures by various ODOT district offices. Task 4: Verify the overall effectiveness of the inspection and rating procedures presented in the ODOT Culvert Management Manual (2003). Task 5: Perform risk assessments of the inspected culverts based on culvert characteristics and data collected. Task 6: Evaluate and recommend the best maintenance and remedial measures for highway drainage culverts. Review new innovative techniques for culvert rehabilitation and replacement. Task 7: Review ODOT procedures for assessing culvert durability based on field data and maintenance records. Task 8: Perform subsurface investigation at selected culvert sites to evaluate the overall effectiveness of the cone penetration test (CPT) as a new field test method for culverts. |
