Modeling of Geotextile Reinforced Mat Placed on Soft Dredgings

Geosynthetics in Civil Engineering Construction

Geosynthetics: Cleanup Tools
In addition to their use in liners and drainage systems for new landfills, geosynthetics can be used in environmental remediation projects. In an early example, contaminated muck was removed...

Fly Ash Fills a Valley
The Pennsylvania Department of Transportation (PennDOT) recently placed narly 400,000 tons of fly ash in a structural fill along I-279 near Pittsburgh. The fly ash, believed to be the...

From Soft Soils to Heavy Construction
A new construction technique using geotextiles and upward flowing water is bringing heavy construction to soft shores. Two projects—a truck yard in Seagirt, Md., and a containment dike...

Reinforcement of Constructed Earth

Evaluation of Sand-Filled Containers for Beach Erosion Control: an Update of the Technology
The use of large, sand-filled geotextile containers for coastal erosion protection has increased along Florida's ocean shorelines over the past five years. Technological advances...

Design of Geosynthetic Systems for Waste Disposal
Geosynthetic materials (consisting of geotextiles, geomembranes, geogrids and geocomposites) are currently being used in large amounts to contain solid wastes in landfills, surface impoundments...

Geosynthetics Unearthing New Applications
Geosynthetics are now a $700 million industry. Called geomembranes, geotextiles, geogrids and geocomposites, geosynthetics complement or replace geotechnical designs. Five case studies...

Use of Fabrics in Highways

Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...

Seepage and Leakage from Dams and Impoundments
All major dams and impoundments are usually analyzed to determine the magnitude and location of seepage that can occur under, around or through the structure. More often than not, seepage...

Engineering with Fabric
Geotextiles are lending their strength to construction projects where conventional methods won't work. At Washington National Airport, an embankment was built into the Potomac...

Lining a Pond to Contain Uranium Tailings
Impermeable pond linings combined with geotextile fabric underlinings are a recent innovation in industrial storage pond construction. A case history of a pond site in New Mexico illustrates...

Filter Criteria for Geotextiles: Relevance and Use
Thm general requirements for filters, both granular and geotextile, in one-directional flow applications and the relevant geotextile properties affecting good filtration performance are...

Geotextile-Reinforced Unpaved Road Design
By providing reinforcement, geotextiles improve the performance of unpaved roads, and for a given traffic, the thickness of the aggregate layer can be reduced. This paper explores the...

Highway Applications of Geotextiles
The successful use of geotextiles on poor soils and water in highway subgrades and sideslopes is examined in this two-part article, In Lakeshore Resort Cuts Cost of Road Relocation with...

Synthetic Fabrics for Reinforced Embankments
Non-woven permeable synthetic fabrics have been used in engineering applications for the last ten years. Considerable research has been conducted throughout the world since the first geotechnical...
