Abstract:

The overarching objective of this project is to identify settlement criteria for embankments and retaining walls and develop a systematic soil improvement design tool to facilitate the method selection and construction time and cost estimation. There is a consensus that the post-construction settlement has profound impacts on the service conditions of roadways and bridge approaches. However, there is no widely accepted settlement criterion in the nation, so each states practice differently. This project surveyed 49 state DOTs on their settlement criteria based on their zoning of bridge approach embankments. 23 out of 49 state DOTs responded to the survey and provided their information on settlement requirement and zoning. The collected data indicate that most state DOTs have their own settlement requirements for embankments, particularly, for the embankment supporting the bridge approaches.
