Prevention and Mitigation of Surficial Slope Failures on Highway Embankment Slopes

The objective of this synthesis is to document state DOT current practices on training for, design, identification, prevention, and mitigation of surficial slope failures. Information to be gathered includes (but is not limited to): (1) Design of new embankment slopes, specifically related to surficial stability; (2) Use of embankment slope materials; (3) Maintenance costs to repair surficial slope issues; (4) Proactive methods used to address surficial instability; (5) Mitigation techniques for addressing surficial slope instability; and (6) Impact of regional climate focusing on rainfall and temperature.
