  • Why Geocells Outperform Geogrids for Road Construction

    Geocells (cellular confinement) offer a more effective and practical 3D design solution to load support challenges than multilayered 2D geogrid efforts. Geocells transfer applied loads instantaneously, delivering practical soil stabilization in a product that is fast and easy to install. How do geogrids work? Geogrids rely on rutting, displacement and lateral movement of the road ...

  • Hybrid Geosynthetic Solution for Rail Track on Expansive Clay, Geo-Americas 2016 Conference Proceedings, Kief (2016)

    Challenge – Reducing Track Maintenance on Expansive Clay Areas of expansive weak clay subgrades invariably change as a result of seasonal changes in moisture content. For rail track in these areas, the resultant heaving and shrinking causes severe degradation of rail alignment, requiring extensive maintenance. One such area is northern Israel, where the Israel Railway Authority ...

  • Commerce Park Giesen-Harsum-Hildesheim case study

    Building on an old dump The communities Giesen and Harsum along with the City of Hildesheim, Germany jointly planned the construction of a commerce park covering an area of 240ha. The section of the premises on which buildings were to be erected encompassed an area of 50ha. The only access road passed over a former garbage and building-trash landfill. Dumping in this area was ...

  • A grid for subgrade stability

    With research to back up quantifiable benefits and recognized design standards, the use of geogrids may be ready for wider acceptance among North American railroads. A product with a 20-year plus track record is rarely referred to as "new." However, this is a label those involved with geogrids find themselves tagged with when it comes to the prod¬uct's use on North American railroads. While ...

  • Effects of Sustained and Repeated Tensile Loads on Geogrid Embedded in Sand

    Design methods for reinforced soil structures under static loading conditions are relatively well established. Little research has been conducted on the behavior of embedded geosynthetics subjected to repeated loadings. Such research is needed to improve the design of reinforced soil structures subjected to traffic and seismic loadings. The study reported here is related to the long-term ...

  • Bearing Capacity of Strip Foundation on Geogrid-Reinforced Clay

    Laboratory model test results are presented for the ultimate bearing capacity of a strip foundation supported by a saturated clay layer reinforced by layers of geogrid. The tests were conducted in one type of clay. The average moisture content of the clay was varied, yielding varying undrained shear strengths. Laboratory tests were conducted to determine the critical nondimensional values for the ...

  • Ultimate Bearing Capacity of Rectangular Foundations on Geogrid-Reinforced Sand

    Model test results for the ultimate bearing capacity of rectangular surface foundations supported by geogrid-reinforced sand are presented. The tests were conducted using one type of sand at one relative density of compaction with only one type of geogrid. The length-to-width ratios of the model foundations were varied as 1, 2, 3, and 8. Based on the model test results, the maximum required ...

  • Enhancement of the Uplift Capacity of Buried Pipelines by the Use of Geogrids

    The paper presents the results of preliminary tests that were conducted to investigate the possible use of geogrids for increasing the uplift resistance of buried pipelines. The results of the preliminary experimental investigations suggest that the uplift capacity of a pipeline section can be increased quite significantly by the incorporation of geogrids at the crown region of the pipeline in an ...
