Geotextiles civil application

High performance fibers are generally characterized by remarkable unit tensile strength and resistance to heat, flame, and chemical agents that normally degrade conventional fibers. Applications include uses in the aerospace, biomedical, civil engineering, constmction, protective apparel, geotextiles, and electronic areas. 

Of particular importance in these application are the long lifetimes. Civil engineering structures can be designed for up to 120 years service. Safety is critical where the geotextile is used for reinforcement, such as in steep embankments, retaining walls, bridge abutments, and embankments built over soft soil or old mineworkings. 

Geotextiles have become one of the most important fields of application for synthetic polymeric fibers. In view of their great importance, we describe them in a separate section. Textiles made of synthetic polymer fibers are used in various applications to address a variety of solids-related problems in civil engineering such as soil support, stabilization, separation and filtration, reinforcement of... 

The design of a geotextile is of paramount importance for any civil engineering application. In the past, it has been suggested that the selection of a geotextile should be realised by the design by function route such that its properties are specified. Some... 

Geotextiles n. Manufactured fiber products made into fabrics of various constructions for use in a wide variety of civil engineering applications. 

Common name for all kinds of synthetic materials including geotextiles, geomembranes, geonets, geogrids, and so forth, used in geotechnical and civil engineering applications. 

For all other applications in civil and hydraulic engineering the test can be carried out at room temperature with a test period of 100 hours using geotextile protective layers with an increased load factor of 2. 

Nonwoven geotextHes are permeable geosynthetics made of nonwoven materials used with soil, rock, or other geotechnical-related material as an integral part of a civil engineering project, structure, or system. They are frequently made from synthetic polymers such as polypropylene, polyethylene, polyamide, and polyester, as well as natural fibres such as jute, sisal, and coir. The European standards (EN) for the specifications and performance requirements of geotextiles in 11 application areas (roads and other... 

Other countries in Europe also had individual investigators working with geotextiles in civil engineering applications but often lacked the impetus given by large chemical companies which had the resources in both personnel and materials as mentioned. 

The six main functions of geotextiles are separation, reinforcement, cushion/protec-tion, filtration, drainage, and barrier. These functions can be used in various applications in environmental and civil engineering and construction.
