Estimation of Soil-Water Characteristic Curves in Fouled Ballast

Dr. Stacey Kulesza, P.E., Robert Sherwood, and Dr. Michelle Berry, P.E. exam fouled ballast and soil-water characteristic curves, in this latest share from the GAP 2019 transportation engineering conference proceedings (Colorado Springs, November 2019). Geosynthetica published the proceedings. The team's research is extremely valuable, as ballast fouling can impact the safety and performance of railway tracks. The work also exemplifies one of the hallmarks of the railroad industry: it succeeds through a strong partnership between public and private research, threading safety and long-term performance into all manners of monitoring and operations. The primary research in this article was funded by the Federal Railroad Administration (FRA) Broad Agency Announcement. The contents of this paper reflect the views of the authors and...
