Book Description
Geosynthetic materials have entered the mainstream in the professional arena and are no longer considered new construction material. Professionals need to keep up with the nuances of how geosynthetics work. Emphasizes design by function; overviews all types of geosynthetics, with stand-alone units on particular materials. Uses S.I. units for all problems and examples. Expands coverage of containers and tubes in the geotextile chapter. Discusses walls and slope design, including seismic analysis, in the geogrid chapter. Treats wet landfills, agricultural waste, waste stability, and dam waterproofing in the geomembrane chapter. Discusses new products and related performances in the geosynthetic clay liner chapter. Discusses new products and related behavior, including fiber reinforcement and wall drainage, in the geocomposite chapter. Adds a completely new chapter on geofoam. A useful reference for transportation, geotechnical, environmental, and hydraulics professionals and engineers.

Book Description
This Report to Stakeholders reviews some of our transportation research efforts in Wisconsin during the past four years. A few of these studies are already complete and have made a significant impact on the way we do business. Many of the projects will be finished in the coming months. For all of us interested in Wisconsin's transportation future, the report provides an overview of these diverse and laudable investigations.

Book Description
This volume contains contributions on advances in geosynthetics engineering. Soil reinforcement is a very useful technique to construct several cost-effective soil structures in an environmentally friendly and sustainable manner. The most commonly used reinforcement materials are galvanised steel strips, geosynthetics in the form of woven geotextiles, geogrids and geocomposites, and fibres from natural and waste products. In recent years, there have been advances in the area of soil reinforcement, especially in the utilization of the technique in field projects. The researchers have also been working to understand the behaviour of reinforced soil considering the field challenges of reinforced soil structures. The volume is based on the best contributions to the 2nd GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2018 – The official international congress of the Soil-Structure Interaction Group in Egypt (SSIGE).

Book Description
State departments of transportation (DOTs) routinely use geogrids and geotextiles for subgrade stabilization. There is a general consensus between state DOTs concerning the effectiveness of these geosynthetics for this application; however, there is a lack of understanding and agreement with respect to the material properties of the geosynthetics that most directly relate to performance. A full-scale field study using geosynthetics as subgrade stabilization was conducted to analyze the performance and transverse behavior of 14 reinforced test sections under vehicular loads. Insight into the mechanisms of support that geosynthetics provide was determined based on strain gage and LVDT measurements, and transverse rut profiles. Mechanical properties of geosynthetics were compared to truck passes at the transition from lateral confinement to membrane support as well as at failure to evaluate which properties best predicted field performance. The properties evaluated included wide-width tensile strength, cyclic tensile modulus, resilient interface shear stiffness, junction strength, and aperture stability modulus. The behavior of geosynthetics was primarily characterized by when they started to transition from lateral confinement to membrane support. The results indicate that in general, the geosynthetics transitioned between truck pass 80 to 300 at a corresponding average elevation rut of about 1.7 inches, or between 1.7 to 3.1 inches of apparent rut. Failure was defined as 3 inches of elevation rut, and in general, the geosynthetics that transitioned to membrane support before truck pass 80 to 300 failed early. The results from the field study indicate that junction strength and stiffness, and wide-width tensile strength at 2% and 5% strain may be the most pertinent mechanical properties of geogrids, and surface friction may be the most pertinent property of geotextiles, for estimating field performance when used for subgrade stabilization applications with 10 to 12 inches of base aggregate, CBR strength values between 1.5 to 2.2, and elevation ruts less than 3.0 inches (or less than 5.4 inches of apparent rut).
