PRS-Neoloy® Geocells optimize the performance of both railways track and rolling stock and maximizes the economic worthiness of new track construction and track rehabilitation. Safe and efficient operations of railways seek to minimize degradation of mainline track surface geometry and ballast layers; this is critical on track with high speed passenger operations and/or heavy freight loads.
This section describes how Neoloy® based cellular confinement system (geocells) reinforces track substructure and stabilizes the ballast layers, subgrade and embankments to minimize track degradation and maintenance cycles.
Railway Reinforcement
Track geometry and maintenance is very sensitive to the track substructure, subgrade and/or ballast conditions and train speeds and loads.... (Read more)
Railway Embankments Stabilization
Neoloy Geocell confinement can be used to reinforce embankment at the foot of soft subgrade or at the middle /top... (Read more)
Railway Earth Stabilization
Neoloy Geocell gives engineers a single soil stabilization strategy for an entire railway infrastructure project. In addition to load support,... (Read more)
Ballast Confinement
Unconfined ballast spreading laterally and causing settlement is a main reason for track maintenance. Attrition from the relative movement of... (Read more)
Subballast Reinforcement
The long-term performance of the substructure under the ballast layer is critical as it is not subject to regular maintenance.... (Read more)
