  • Soil-Geogrid Reinforcement Interaction by Pullout and Direct Shear Tests

    Pullout and direct shear tests have been conducted to investigate the soil-reinforcement interaction behavior in pullout and direct shear mechanisms. An apparatus—discussed in this paper—has been developed that is capable of performing both pullout and direct shear tests. Displacement measurements to monitor dilatancy on the backfill soil during pullout tests are incorporated in the apparatus. ...

  • Shear Strength Tests for Coarse Granular Backfill and Reinforced Soils

    In order to overcome the limitations of the current standard small direct shear box in testing the shear strength of coarse granular backfill materials, a large direct shear apparatus (1000 by 1000 by 940 mm) was constructed at Carleton University and a series of direct shear tests were conducted with coarse granular soils. In addition, several direct shear tests on soils reinforced with geogrids ...

  • Pullout Resistance of Steel Geogrids with Weathered Clay as Backfill Material

    The pullout resistance of welded steel geogrid reinforcement embedded in poor-quality, cohesive-frictional backfill material such as weathered clay was investigated. Laboratory pullout tests were conducted on various reinforcement sizes, mesh geometry, and compaction conditions of the backfill material. Field pullout tests were also conducted to investigate the pullout resistance of ...

  • 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 ...

  • How Strata’s Microgrid reinforced a roadside slope and saved 30-percent in costs

    Challenge The City of Fairfield in Solano County, CA has many beautiful parks and trails enjoyed by residents year round. One of roadways stretching alongside one of these natural areas was threatened due to unstable soils and a failing slope. This posed safety concerns for the area. The roadway had a right of way to a state highway and the county and city were in need of a cost effective ...

  • Clemson road bridge case study

    Background The South Carolina Department of Transportation (SCDOT) needed to provide a right-of-way for an access road adjacent to a CSX Railroad line. The proposed Clemson Road Bridge overpass was a challenging project and SCDOT had three choices: Option 1: Construct a 1H:1V Reinforced Soil Slope (RSS) at the northern bridge abutment. Option 2: Lengthen the northern ...

  • Titan Geosynthetics: A Major Solution for CN Rail - Case Study

    The Canadian National Railway (CN Rail) wanted to build an additional 6-track extension at the Transcona yard in Winnipeg, Manitoba. Heavy rail cars were expected to pass over this extension area and CN Rail was looking for an economical, fast, environmentally friendly and technically sound solution for their track extension. The site had swampy conditions with wet and soft clay soils. In fact, ...

  • Ämmässuo landfill, Finland case study

    Opened in 1987, the municipal landfill Ämmässuo in Finland extends over 50 ha, making it one of the largest in all of Scandinavia. Two test fields were set up to find a suitable solution for the surface sealing system and future slope reinforcement The structure of these fields consists of a mineral gas-drain layer, a mineral sealing layer, a geosynthetic clay liner, a protection ...

  • Case study - Log storage handling yard

    The logging yard at Canfor’s Fort St. John mill is subject to the heaviest loading operations in the worst soil conditions. Saturated peat with a CBR Cat 988H loaders weighing more than 43,000 kg, heavy hauling trucks, and other mechanical equipment created heavy rutting in the soft soil. The logs, stockpiled in huge, 6-metre high stacks, suffered from large settlement, which further ...
