Synthesis of Information Related to Highway Practices. Topic 50-06. Recent Advances in Unstable Slope Instrumentation and Monitoring

Landslides and unstable slopes pose a threat to public safety and mobility and increase the cost of maintaining the nation’s highway system. Recent innovations in geotechnical instrumentation and monitoring technologies have the potential to improve the resilience of our highway systems. Performance monitoring programs are useful in at least three ways: 1) providing information on the rate of movement and triggering mechanisms, useful for remediation designs, 2) acting as early-warning-systems to alert maintenance forces when to take additional actions, and 3) providing a clearer picture of the risk associated with the monitored sites so that funding can be directed to the most critical sites first. The objective of this synthesis is to document the current state of practice for geotechnical instrumentation and monitoring for landslides and unstable slopes. The synthesis will focus on the application of new technologies implemented by state departments of transportation (DOTs). Technologies of interest include those used for in-situ instrumentation, remote sensing, data acquisition, local data storage and transmission, and data presentation and visualization. Case examples will be prepared illustrating the DOT use of and experience with specific technologies. The synthesis will describe types of technology, not proprietary products. Information will be gathered through literature review, survey of state DOTs directed to chief technical engineers, and follow up interviews with selected agencies for the development of case examples. Knowledge gaps and suggestion for research to address those gaps will be identified.
