Mechanical Stabilization for Improved Trackbed Performance

Duration: 1 hour

In this video, we will provide an introduction to the use of geogrid for the mechanical stabilization of ballast and sub ballast in rail track structures. The discussion will include:

  • Benefits of mechanical stabilization of track structures and operations
  • How geogrid works to stabilize granular materials
  • Introduction to the applicable design methodology and AREMA guidelines for geogrid use
  • Project examples
  • Practical design and construction considerations.

This course may serve as one (1) Professional Development Hour - Completion of Video is Required to Obtain Certificate.
