    • Abstract:
      The Montana Department of Transportation (MDT) commissioned a new research program to improve assessment and management of its rock slope assets. The Department implemented a Rockfall Hazard Rating System (RHRS) program in 2005 and wished to add value to that existing program by adding new slopes and reassessing select ones, incorporating new rating approaches, and leveraging that data to generate a new prioritized list for consideration of mitigation projects. An ideal framework for a refreshed program would be consistent with modern transportation asset management (TAM) principles. These tools are useful across Departmental groups, from the core group of Geotechnical personnel, technical groups such as Roadway Design, to groups with more broad missions, such as Asset The Montana Department of Transportation (MDT) commissioned a new research program to improve assessment and management of its rock slope assets.

An ideal framework for a refreshed program would be consistent with modern transportation asset management (TAM) principles. These tools are useful across Departmental groups, from the core group of Geotechnical personnel, technical groups such as Roadway Design, to groups with more broad missions, such as Asset Managers and Department Planners. The resulting program, renamed the Rock Slope Asset Management Program (RAMP), is expected to reduce overall rockfall hazard to the public while helping MDT manage the cost of rock slope maintenance and mitigation work by offering decision support tools, risk assessments, and economic models suitable for incorporating network-level condition forecasting for various investment scenarios.
