A portion of a railway track in Fort Lauderdale, Florida had been a high maintenance area for many years due to the impact loads from rail cars transitioning off of a concrete bridge abutment onto ballasted concrete ties. The ties were located over soft subgrade, which had exhibited a history of pumping. The rail operator, Florida East Coast Railway, sought a ballast stabilization solution to corr... »

Oregon State University’s Dr. Ben Leshchinsky, P.E. and the University of Kansas’s Dr. Jin Han, P.E. recently combined their wealth of geosynthetics knowledge in a track ballast research study. Specifically, they evaluated the performance of a high-density polyethylene geocellular system (HDPE GEOWEB® from Presto Geosystems) in a railway base stabilization system. The rigorous track testing quanti... »
