INTRODUCTION
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 efficiently over the underlying subgrade, leading to a reduction in the required sub-ballast layer thickness.
Including Nilex’s geogrid and geotextile products in trackbed design improves the subgrade support – and ultimately the lifespan of the structure – by reducing and spreading the stress on the weak subgrade.
SUB-BALLAST STABILIZATION PRODUCTS
Biaxial Geogrids improve the structural integrity of roads and railways and Mechanically Stabilized Earth (MSE) Walls and Slopes by confining and distributing load forces. Geogrids provide support for the construction of access roads, highways and applications on weak subgrades that previously...
The EnviroGrid cellular confinement system (geocell) is produced from High Density Polyethylene (HDPE) and has three dimensional cells that contain, confine and reinforce a variety of fill materials including native fill, topsoil, granular or concrete. This material has excellent resistance to...
Nonwoven Geotextiles have a wide range of applications in civil environmental engineering and construction projects. Their uses include...
NEW - TriAx TX8 Geogrid Now AvailableTriAx Geogrid is a revolutionary product from Tensar. The triangular structure of TriAx Geogrid, coupled with the increased rib thickness and junction efficiency, greatly improves aggregate interlock and confinement – leading to optimal structural...
Nilex Woven and High Strength Woven Geotextiles are often used for separation and stabilization in the construction of roads. The woven geotextile’s separation action prevents the mixing of dissimilar soils allowing each soil layer in the road structure to function as intended. The high...
MARPOLE SPUR TRACK EMERGENCY SUBGRADE REPLACEMENT
An outage on one of CP Railway’s spur lines required a rapid response, including both design and product supply. The poor quality of material in the subgrade below the railway tracks was noted as the primary cause of the failure. The solution to stabilize this location would require subgrade…
