Track Stiffness: Measurement System Evaluation Program
This report describes a three-phase program to develop and evaluate an on-board, track stiffness measurement system. High correlation has been established between observed variations in track stiffness signatures and the actual conditions of track structures and subgrade. Track stiffness and track geometry were found to be independent and complementary measurements. A detailed study of long-and short-span bridge stiffness signatures was conducted. An analytical study of the relationship of the mid-chord-offset difference to absolute stiffness for bridge structures and continuous roadbed was made. Theoretical stiffness models were matched to actual short-span bridge stiffness signatures.
