Ballast Research Highlighted in RT&S

April 2018: Illinois ballast research was recently highlighted in the March 2018 issue of Railway Track & Structures (RT&S) Magazine. Supported through AAR’s Technology Outreach research program, this research developed a new approach to inspecting railroad ballast and measuring its condition in the field. This innovative technique uses cross-section digital images of ballast and a machine vision system to measure the size of ballast particles and estimate ballast degradation. Transportation Technology Center, Inc. (TTCI) performed investigative field work at their Facility for Accelerated Service Testing (FAST) near Pueblo, CO. Click here to read the article.
