Experiments were conducted in a loading frame filled with ~24 inches of ballast material. A track panel (half-crossties and rail) were placed on top of the ballast and vertical loads were applied to the rail at the center crosstie using a manual hydraulic jack reacting off of the top cross beam of the loading frame. Pressure gauges were placed in the ballast to record the crosstie-ballast interaction. Tests were performed in September 2020.
A series of bending tests were performed on concrete beams in 2007 by grad student Amanda Bordelon under the supervision of Prof. Jeffrey Roesler. Beams were tested in 3-point and 4-point bending configurations. Well defined post-peak behavior was achieved.
A series of tests were conducted on High-Performance Fiber Reinforced Cementitious composites using the Bi-Axial 100 kip testing frame. This project was sponsored by NEES under supervision from Prof. James LaFave; graduate student Raymond Foltz was the leading person in instrumentation, testing procedure, and data analysis. Specimens were subjected to bi-axial state of stress, and the tests were carried out in February 2009.
