Book Synopsis Advances in Geosynthetics Engineering by : Mohamed Meguid
Download or read book Advances in Geosynthetics Engineering written by Mohamed Meguid and published by Springer. This book was released on 2018-10-28 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Evaluation of Transverse Behavior of Geosynthetics when Used for Subgrade Stabilization by : Zachary Lee Morris
Download or read book Evaluation of Transverse Behavior of Geosynthetics when Used for Subgrade Stabilization written by Zachary Lee Morris and published by . This book was released on 2013 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book Synopsis Field Investigation of Geosynthetics Used for Subgrade Stabilization by :

Available in PDF, EPUB and Kindle. Book excerpt: The use of reinforcement geosynthetics in unsurfaced roads built upon a soft subgrade is known to provide benefit through better distribution of applied loads and increased bearing capacity. This report describes a research project where field test sections were constructed to evaluate the performance of several geosynthetics commonly used for subgrade stabilization. A sandy clay soil was prepared as a weak roadbed material to a CBR strength of approximately 1.8 and a 20 cm thick aggregate layer was compacted over the geosynthetics. Trafficking was provided by a fully-loaded tandem axle dump truck. Longitudinal rut depth, along with discrete measurements of displacement and pore pressure were monitored throughout the trafficking period. Post-trafficking excavations were conducted to evaluate damage to the geosynthetic, base contamination and deformation of the layers.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The implementation of geosynthetics in road construction in the United States dates back to the 1970s. Although the benefits of these materials are widely recognized, actual design and construction practices are not universal. Guidelines for use are often developed locally based on specific field experience. Currently, the Virginia Department of Transportation (VDOT) provides specifications (but no design guidance) for only one function of subgrade geotextile: stabilization. Pavement layer separation is not explicitly addressed by VDOT. This study reviewed corresponding practices at other transportation agencies, focusing on subgrade and pavement applications. In addition, observations gathered from field testing of two known sites with geosynthetics in Virginia were analyzed. Finally, life cycle cost analyses (LCCAs) were performed on two common secondary road designs, each with the options of separator geotextile and preventive maintenance, to estimate comparative costs under three different rates of subbase contamination by fines migrating from the subgrade. The LCCA employed actual VDOT cost data and conceptual pavement layer deterioration curves that are based on AASHTO curves augmented by differentiated subbase deterioration resulting from three hypothetical contamination rates. Unlike the current LCCA used by VDOTs Materials Division, the LCCA model developed in this study explicitly recognizes the fact of potential subbase layer deterioration because of contamination by subgrade fines, comporting with the widely recognized function of geotextile separator. The results indicate that separator geotextile imparts long-run cost-effectiveness relative to pavements without geotextile separators at contamination rates of 0.1 in per year and greater. At contamination rates of 0.05 in per year and lower, the addition of separator geotextile is not cost-effective, although the results vary slightly depending on the treatment of estimated pavement design life remaining at the end of the analysis period. The study recommends that VDOT revise its current specifications to include subgrade separation and subgrade stabilization geosynthetics as separate and distinct pay items, and it provides suggested specification language to effect this change. Guidelines to implement these changes are also enumerated.
