Studies of Neoloy Geocell 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 Geocells that showed a 7x reduction in track maintenance; Kief’s published results of hybrid reinforcement projects showing how Neoloy Geocells 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 Geocells cut vertical deformation and lateral displacement by >50% and increase track stiffness by >160%.
