Roadway slopes and embankments are considered geotechnical assets by the FHWA and are an important part of asset management programs being implemented, developed, or discussed from the Federal to the local level. Evaluation, management, and maintenance of roadway slopes and embankments are critical steps in mitigating risk, supporting financial decisions, protecting public safety, and ensuring mobility, especially during natural disasters and times of crisis. In this presentation, different types of slopes and the physical processes which affect their stability will be reviewed, along with visible signs that may indicate slope movement is occurring. Some common slope stabilization methods will be discussed, and innovative technologies and methods will be introduced. Design concepts for stabilizing and repairing roadways impacted by unstable slopes and landslides will be demonstrated through project examples.
