SUBJECT: Tracks & Structures, Evaluation
KEYWORDS: Subgrade, Ballast Performance, Conventional Railway Track Support System, Materials Testing, Material Properties
ABSTRACT: The ballast, subballast, and subgrade materials from the FAST Project at Pueblo, Colorado were evaluated. Conventional characterization testing and repeated load triaxial testing were conducted with the various materials. The data included in this report were developed for bulk material samples forwarded to the University of Illinois. The test results do not reflect any "material variability" which would be encountered in the completed FAST Project.
