Studies of Neoloy Tough-Cell Stabilization of Railway Tracks, Ballast and Embankments Extensive technical papers include Palese, Zarembski (et al) published results of extensive monitoring of an Amtrak rail stabilization project with Neoloy Tough-Cells that showed a 7x reduction in track maintenance; Kief's published results of hybrid reinforcement projects showing how Neoloy Tough-Cells reduce heaving of expansive clay soils; and B. Leshchinsky and Ling's published research on loading tests and numerical analyses of model rail embankments that demonstrated Neoloy Tough-Cells cut vertical deformation and lateral displacement by >50% and increase track stiffness by >160%.
