Impressive Research on Railroad Ballast Improvements Using GEOWEB® Geocells
Every year, railroads dedicate a great deal of capital and maintenance expense towards the creation and upkeep of high quality ballast layers. Enduring well-designed ballast is quite literally the foundation on which a successful rail line operates. With ballooning rail traffic carrying heavier loads than ever, GEOWEB cellular confinement (Geocells) effectively takes the pressure off critical ballast systems.
Oregon State University (OSU) recently performed state-of-the-art, three-dimensional dynamic Finite Element modeling to analyze the reinforcing benefit of GEOWEB geocells in railway applications. This study was completed in cooperation with the University of Kansas (KU) who simultaneously performed a testing program of Geocell reinforced ballast placed over weak subgrade material using HDPE GEOWEB material.
GEOWEB 3D confinement was proven to effectively reduce the pressure, movement and settlement of critical ballast systems, decreasing maintenance and increasing ballast life.
