Monitoring the performance of Louisiana’s first GRS–IBS bridge

June 1, 2018

Over the decades, soil mass reinforced by layers of geosynthetics has been used widely and successfully in a variety of earth structures, such as mechanically stabilized earth (MSE) retaining walls, embankments, slopes and shallow foundations. Due to the proven benefits of geosynthetic reinforced soil (GRS), including cost-effectiveness, simple and fast construction, and tolerance of differential …

Springtime failure of a cold-climate geotextile riprap slope

Geotextiles play an essential role in geotechnical projects. A significant use for geotextiles is as a separator and filter in drainage and erosion control applications (Holtz 2002). A temporary erosion control application geotextile, such as silt fencing, is used to prevent soil erosion by containing the soil and turbid water in a onetime operation. For …

Highway deep-patch geogrid applications

Deep patch is a repair technique that has been widely used on low-volume roads in the Pacific Northwest as a cost-effective mitigation technique to address settlement and shallow landsliding of side-cast embankment fill slopes and natural slopes consisting of weak soils overlying stronger soils (Cuelho et al. 2012). A deep patch consists of a subexcavation …
