Rail Structures

Introduction

The American Railway Engineering and Maintenance of Way Association (AREMA) has recognized the value of geogrid technology for trackbed stabilization by including a chapter on geogrid in its 2010 Manual for Railway Engineering. Several factors including, but not limited to, car weights, car velocity, tie type and dimensions contribute to the design of the trackbed, which would incorporate specific loading and subgrade conditions.
Nilex can provide cost effective alternatives to traditional construction methods, such that the developed design trackbed sections are in full compliance to AREMA guidelines, together with pavement sections for intermodal facilities.

Solutions

Ballast Stabilization & Optimization

For all classes of railways Nilex’s geogrids provide a proven solution to ballast reinforcement and optimization. Structures can fail prematurely due to the lateral displacement and weakening of the ballast fouling. The structural strength provided by Nilex’s geogrid products can allow for...

Sub-Ballast Stabilization

Often poor subgrade soils do not possess the strength to support trackbed construction activities and the subsequent AREMA requirements. Installed at the bottom of the sub-ballast, Nilex’s subgrade separation and stabilization geosynthetic materials help distribute imposed loads more...

Highway 50 Blue Mesa ACE Fiber Overlay Reinforcement

Colorado highways are subject to two conditions many states are lucky to avoid: High elevation and extended periods of low temperature. Combining those elements with heavy traffic loads, the stretch of U.S. Highway 50 running past Gunnison, Colorado, has experienced rutting and cracking. The...
