Each year railroads must allocate a significant portion of their capital and maintenance budget toward 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 (geocell) 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. Completed in cooperation with the University of Kansas (KU), who simultaneously performed a testing program of Geocell-reinforced ballast placed over weak subgrade. The digital modeling results were reinforced by the laboratory tests and showed a significant decrease in settlement of the railway ballast when GEOWEB confinement was used. Using the GEOWEB system not only decreased settlement but also reduced pressure on point-to-point aggregate load transfer contact. This resulted in less damage to ballast aggregate particles leading to less progressive deformation and longer maintenance frequencies of the entire ballast embankment. In short, more cycles mean less track down-time for maintenance. The research results were clear. The benefits of applying GEOWEB Geocell confinement for reinforcement of real ballast over weak… Read more »
