Service Evaluation of Highway Structures with Soil-Bearing Spread Footings
The Ohio Department of Transportation (ODOT) needs to evaluate highway structures’ performance supported on spread footings bearing on soils. This evaluation’s outcomes are recommendations for future use of spread footings and potential limitations on their use. The project team completed the following tasks: 1. Reviewed the documented performance data. 2. Evaluated the performance of existing footings and compare to the bridge performance criteria. 3. Reviewed the calculated settlement. 4. Provided an estimate of the structure tolerable settlement at the foundation location. 5. Compared the measured settlement to the predicted long-term settlement. 6. Compared performance to soil conditions and calculated bearing pressures. 7. Reviewed IRI (International Roughness Index) and differential settlement between substructures. The data collected and the field review of all four sites included in this research showed that spread footing supporting structures perform as intended, and there were no signs of settlements and rideability issues. Spread footings constructed following the manuals and procedures by ODOT will perform satisfactorily. The requirements for monitoring of the settlement using rods specified in the plans need to be augmented with survey targets at the substructure units above finished ground for comparison and verification of plumbness of the substructure unit.
