Using Railroad Ballast For Highways

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 Geocell effectively takes the pressure off critical ballast systems.

Railroad Ballast Performance Improvement Using Geoweb

Railroad Ballast Performance Improvement Using Geoweb

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.

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. The use of GEOWEB technology not only decreased settlement, but reduced pressure on point-to-point aggregate load transfer contact which in turn 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 cy

The benefits of GEOWEB confined ballast are substantiated through rigorous testing. Conventional ballast reinforcing materials eg geogrids, Hot Mix Asphalt HMA do not have the strengthening attributes that GEOWEB geocells can provide, especially in soft subgrades. Building a more stable ballast layer with less settlement, higher shear strength, and less maintenance requirements is possible when built with GEOWEB geocells.

The classic mainline freight railroad is likely what most people will visualize when picturing how a railroad appears, and is therefore generally the inspiration for most ballasting on model railroads. While it is generally a consistent gray tone, there are some steps you can take to make it more authentic looking.

Railroad Ballast Evaluation Using Groundpenetrating Radar

Railroad Ballast Evaluation Using Groundpenetrating Radar

Ground-penetrating radar GPR, a nondestructive evaluation tool, has shown its potential as a means of assessing the condition of the railroad substructure rapidly, effectively, and continuously. However, an unknown ballast dielectric constant and an unclear interface between clean and fouled ballast limit the accuracy of GPR assessment.

Apr 08, 2017nbsp018332I live just downslope from an active railroad track. It was covered by stinging nettle, but Ive removed most of it over the years. I need something to plant there beside the morning glory and small trumpet vines to cover the gaps. It is a steep sloping grade with solid ballast rock, and I dont want the nettle taking back over. I have a periwinkle patch elsewhere. Would that possibly work ...

How To Realistically Ballast Your Railroad

In large scale and small, ballast is a vital component for a successful railroad. Good, uniform ballast on a full-scale railroad helps secure ties and keep them dry from the elements. On a model railroad, ballast serves to add realism and depth to your scene when done correctly. When it comes to selecting model railroad ballast for the trackage on your layout, the goal should always be to create visual intrigue.
