Pressure Distributions and Magnitudes at the Tie/Ballast Interface

This project will further ascertain pressure distributions and magnitudes at the tie/ballast interface from various combinations of wheel loads, train speeds, and ballast/track conditions for high-speed, heavy tonnage freight railroads. The overall objective is to determine relative effects of the factors on pressure distributions along track having both adequate and poor support. 1. Prototype tests will be conducted at the University of Tennessee full-scale track testing facility. 2. Pressure cells will be installed at track sites on Norfolk Southern trackage exhibiting both adequate and poor performance to determine the effect of trackbed support on the performance of the track relative to minimizing maintenance costs and extending the life of the track components and providing overall enhanced trackbed performance. 3. Evaluate results and present to American Railroad Engineering and Maintenance-of-Way Association (AREMA) Committees 1 and 5 for consideration as inclusion in the section on Trackbed Structural Design.
