Application of Track Stiffness Measurements

There is increasing interest in and capability to measure track stiffness as an indicator of ballast and subgrade condition, but limited work on interpreting the data. This project will focus on gaining a better understanding of the significance of track stiffness measurements and how to apply this data in a meaningful way for track fault diagnosis and maintenance planning. The next efforts will involve investigating correlations between various types of stiffness measurements, combined with other track measures, and ballast and subgrade conditions.
