Federal Railroad Administration (FRA) Announces $1.1 Billion Available in the Railroad Crossing Elimination (RCE) Grant Program

The inaugural Railroad Crossing Elimination (RCE) grant program was designed to eliminate or improve roadway and railroad at-grade crossings, with the goal of making roads/rails safer while improving commute times for citizens. According to the U.S. Department of Transportation website, “this program provides funding for highway-rail or pathway-rail grade crossing improvement projects that focus on improving the safety and mobility of people and goods.” The grant program helps fund projects that involve: repairing grade separations, relocating tracks, upgrading or improving protective devices, signals, or signs, maintaining at-grade crossings, and more. With safety as the top priority for the DOT, repairing and maintaining high-impact areas is critical so the potential for collisions or blockages can be prevented. Applications for funding are due no later than 11:59 p.m. EST, September 23, 2024. Visit USDOT website for more information and to apply for funding >> The GEOWEB® System stabilizes high-impact and crossing areas safely and quickly, limiting track downtime. Areas subjected to heavy stresses at bridge approaches, diamonds, turn-outs, and crossings create the highest maintenance and safety liabilities for operations. The GEOWEB Soil Stabilization System (Geocells) is effective in reducing maintenance in these high impact areas. The GEOWEB 3D Soil Confinement System has been… Read more »

Ballast Stabilization Using Geocells

The Often Overlooked Importance of Junction Efficiency as a Key Design Consideration A significant number of research studies have been carried out to investigate the benefits of using geocells in railway track bed applications. Combined with an ever-expanding list of successful projects from around the world, the benefits of using geocells in rail ballast stabilization is well-documented. Rail operators understand that durable track geometry starts with a solid foundation, and geocells have emerged as a powerful value engineering tool for reinforcing ballast and sub-ballast layers while optimizing layer thicknesses. Many practitioners may not be aware of the critical role that geocell junctions (both mechanical and internal) play in ensuring that the installed system performs in a uniform and consistent manner. In track bed stabilization applications, non-uniform junction performance can lead to differential settlement and localized subsidence—which in turn can lead to serviceability issues, damage to the overlying structure/pavement, and a reduction in overall design life. In essence, poor junction performance can nullify all the intended benefits of a geocell system. This article will succinctly discuss the different types of junctions present in geocell systems, failure mechanisms and test methods, and the concept of junction efficiency as a performance parameter.

GEOWEB® Geocell Reinforcement Improves Structural Performance of Railway Track Beds

Every year, railroads dedicate a great deal of capital and resources toward creating and maintaining high-quality track profiles. Providing a well-designed track profile is the foundation on which a successful rail line operates. With ballooning rail traffic carrying heavier loads than ever and increased occurrence of extreme weather events, a stable track profile is essential for successful operation. GEOWEB® geocells have been used in the track bed for rail applications worldwide for more than 40 years. Through an interconnected honeycomb-like network, the HDPE-based GEOWEB Soil Stabilization System provides apparent cohesion and strength to materials that would otherwise be unstable over soft subgrades. Geocells stabilize the ballast, reduce vertical and lateral stresses, and limit ballast movement. Stabilization within the geocell system provides a longer lasting track profile that extends rail service life, while also reducing maintenance cycles and recurring maintenance costs. Research has shown that geocells reduce settlement of the ballast foundation and can reduce required cross-section thicknesses by up to 50%. This is particularly advantageous where track beds must be constructed over soft soils. The reduction in thickness leads to cost savings, along with an accompanying reduction in carbon emissions due to decreases in aggregate processing, transportation, handling, and installation….

Designing Sustainable Ports & Yards with 3D Geocells

Stabilization for Higher-Performing Pavements Ports and intermodal yards in coastal areas are more prone to pavement problems due to inherent soft, unsupportive soils and high water levels. Heavy traffic patterns and the constant weight of loaded parked trailers and stacked containers at these facilities can accelerate the degradation of the paved or unpaved surfaces and subbase materials. The repeated pressure over poor soil conditions results in settlement, ruts, potholes, and even pavement failure. These surface problems require continual, costly maintenance and interruptions to facility operations. But the problem isn’t at the surface—it’s a base stabilization problem. Transforming Base Materials through 3D Confinement Creating and ensuring a stable surface supportive of the long-term, heavy traffic needs starts with better stabilization of the base materials. The GEOWEB® 3D Confinement System is built for this function. The system’s deep, cellular network controls both the horizontal and vertical movement of unstable base soils. When vertical loads are applied, active earth pressures in the loaded GEOWEB® cells push against passive earth pressures in adjacent cells to form a stable system. The benefits of confining fill are applied to both base reinforcement and unpaved surface applications. Permeable Unpaved Pavements Utilizing the GEOWEB® 3D system at the… Read more »
