Shown here is a large retrogressive-type slope failure, which started as a small instability near the embankment toe. |
NHI developed the course Highway Slope Maintenance and Slide Restoration (FHWA-NHI-132081) for transportation field personnel. The instructor-led course, piloted in spring 2008, explains the conditions and factors affecting slope movement, stability, and deterioration, and the cost of maintenance and stabilization. The course also covers the rationale for slope management.
"This course bridges a gap between a department of transportation's maintenance workforce and management and geotechnical and geology staffs," says Rivers. "The intent is to provide field personnel with a fundamental knowledge of factors and conditions that affect the long-term stability and performance of slopes, and to provide best slope maintenance practices, slope stabilization and repair methods, and the fundamental aspects and considerations of managing slopes in relation to our roadway infrastructure assets."
Although the potential audience for the course includes geotechnical, operations, and asset management engineers, geologists, and others involved in assessing, maintaining, managing, and repairing slopes and associated features, the primary target audience is State maintenance workers. Course material does not cover highly technical content but explains key concepts in layman's terms with an asset management perspective.

Proper maintenance and intervention with small slope instabilities, such as this one, can prevent larger, more costly problems. |
Upon completion of the 2.5-day course, participants will be able to discuss common soil and rock slope movement and instability, list factors and conditions under which slopes deteriorate, recognize common soil and rock slope stabilization techniques, and describe the key components of slope management systems. Instructors also underscore the importance of communication and coordination with geotechnical specialists.
