Geotextile Fabric Filter Laboratory Testing Results

Provides information on woven and non-woven geotextiles used for filtering and drainage in geotechnical engineering. The design of such filters balances large pores for adequate permeability with smaller pores for proper soil retention. Of the 15 papers from a June 1995 symposium in Denver, Colorado

This publication, Geotextile Testing and the Design Engineer, contains pa◆pers presented at the international symposium of the same name held in Los Angeles, California on 26 June 1985. The symposium was sponsored by ASTM Committee D-35 on Geotextiles, Geomembranes, and Related Prod◆ucts. Joseph E. Fluet, Jr., of GeoServices Inc. Consulting Engineers, presided as symposium chairman and was editor of this publication.

Geotextiles: From Design to Applications presents valuable information on the high performance fabrics used in soil separation, drainage, filtration, reinforcement, and cushioning. These polymeric materials offer solutions for geoengineering and other civil engineering specialties due to their advanced physical, mechanical, hydraulic, and endurance properties. This important book offers comprehensive coverage of the manufacture, functions, properties, designs, and applications of geotextiles. Part One begins with a chapter on the history of geotextiles, followed by chapters giving detailed reviews of the types of fabrics and their manufacturing processes, from resin type, to fiber extrusion, to textile fabrication. Part Two covers the properties, behavior, and testing of geotextiles, with Part Three focusing on applications dealing with the specific primary functions of geotextiles. In Part Four, chapters offer numerous general applications of geotextiles, including those in waste containment, marine engineering, walls/slopes, agriculture, and erosion control. Finally, the chapters of Part Five address quality control and assurance for geotextiles, and the increasingly important topic of sustainability. Reviews the types of fabrics used for geotextiles and their manufacturing processes Covers the properties, behavior, and testing of geotextiles Contains detailed discussions of the primary functions of geotextiles and their wide range of applications

Geosynthetics in Civil and Environmental Engineering presents contributions from the 4th Asian Regional Conference on Geosynthetics held in Shanghai, China. The book covers a broad range of topics, such as: fundamental principles and properties of geosynthetics, testing and standards, reinforcement, soil improvement and ground improvement, filter and drainage, landfill engineering, geosystem, transport, geosynthetics-pile support system and geocell, hydraulic application, and ecological techniques. Special case studies as well as selected government-sponsored projects such as the Three Gorges Dam, Qinghai-Tibet Railway, and Changi Land reclamation project are also discussed. The book will be an invaluable reference in this field.

First published in 1990. Routledge is an imprint of Taylor & Francis, an informa company.

During the past decade, the use of geotextiles has increased significantly in a wide range of civil engineering applications: road construction, coastal engineering, stabilization of slopes and retaining structures, reinforcement of foundations, drainage etc. This work focuses on the factors which determine the level of long-term performance of these materials such as their mechanical and physical properties and physico-chemical ageing processes. (It includes contributions to an international seminar held at Saint-Remy-les-Chevreuse, France, in November 1986)

Geosynthetics can, and have, played a pivotal role in providing the primary functions of filtration, drainage and erosion control. Within each category this book counterpoints the design, testing and performance of the various materials against one another. The facilitation of filtration by a number of different woven and non–woven geotextiles is discussed. Design is centred around a balance between open voids [for adequate permeability] and closed voids [for proper soil retention]. This balance is compromised by long term clogging or soil loss from either the upstream soil particles or by the nature of the permeating fluid. This is a major focal area of the book. One solution to excessive filter clogging is to open up the geotextile's voids and allow sediments and micro–organisms in the permeating fluid to pass through. The challenge then becomes the design and potential clogging of the drain. The drainage aspect of geosynthetics is the second focal area. Erosion control is closely related to both filtration and drainage. The tremendous design problems, and equally large repair problems on all types of facilities, are addressed. Highway slopes, earth dams, landfill covers and solid waste daily covers are a few common situations.
