The Concept Of Geotextiles
Meaning of geotextile
A geotextile is a synthetic permeable textile material applied with soil, rock, or any other geotechnical engineering related material. It is produced by synthetic fibers made in a woven or loose nonwoven form. Geotextiles, also named as geosynthetics, are normally applicable to high-standard all-season roads, can also be used to low-standard logging roads.
American Society for Testing and Materials (ASTM), describes geotextile as any permeable textile material applied with foundation, soil rock, earth or any other geotechnical engineering related material as an integral part of a: man-made project, structure or system.
Application
Geotextiles are mostly used for: Reinforcement of Unpaved Roadways, Paved Roadways, Separation applications in Unpaved Roadways, Paved Roadways, Sediment Control etc, as part of geo-composites.
Historical background of geotextile
Geotextiles are existed with more than fifty year. Though, the development of market and research work put in to practice in early 1960's. The first international conference on the application of fabrics in geotechnics was held at Paris in 1977.The Industrial Fabrics association International (IFAl) started geotechnical division in 1980.
The second international conference of geotextile was held at Las Vegas, sponsored by IFAI in 1982, where decision was taken to build an International Society of Geotextile (ISG) and later on ISG was created in 1983. ISG created a sub-committee SC-21 on geotextile (related to existing technical committee TC-38 on textiles); International Society for Soil Mechanics and Foundation Engineering (ISSMFE) agreed to formulate a technical committee on geotextile in 1983.
In 1992, The Indian Chapter of the International Geosynthetics Society (IGS) and the Committee for International Geosynthetics Society (India) - CIGSI were established and in 1998 the first Indian geotextile conference was held at Mumbai.
The basic functions of geotextiles
Geotextiles normally give the following functions:
. Separation/filtration
. Reinforcement
. Drainage
. Hydraulic or moisture barrier.
It is noted that due to wide changes in their characteristics of the materials for geotextile together with range of feasible fabric/grid structures, geosynthetics perform the above functions and provide considerable advantages over the conventional methods and materials.
Application-wise progression of geotextiles
Progression of the geotextiles can be generally classified into its various generations.
. The first generation geotextiles: The first generation of geotextiles used for such applications like carpet or industrial sackings.
. The second generation geotextiles: The second generation of geotextiles was made by the producers by selecting specific textiles with consideration of their appropriate geotechnical intention, but by means of conventional manufacturing techniques.
. The third generation textiles: The third generation textiles were then really intended and built up particularly for the purpose of geotechnical uses - specifically Directionally Structured Fibers (DSF), Directionally Oriented Structures (DOS) and composite products.
Geotextiles are performing progressively in civil engineering construction and are still growing as an alternative, economically viable material. In recent years, the utilization of geotextiles in the world markets has grown at extraordinary rate. In India, geotextiles have been specially used in road and airport flexible pavements and in overlays.
The growth of geotextiles in between 2000 and 2005 was grown at the rate of 4.6% annually, and during the next five years (i.e. up to 2010) it is predicted to 5.3 percent. The geotextile market is increasing in its growth rate, though these are now lower than previously forecasted and in compared to other applicators it has relatively little growth for end-user of textiles. In the quantity, geotextiles reported a little growth, more than 250,000 tons in 2000, merely 1.5 percent of the overall technical textile market. Furthermore, this sector with low unit values in small numbers gives a large margin.
Description of basic functions of geotextiles
The important functions of geotextiles as mentioned above are briefly described below:
Separation
The separation task means, the separation of two different soils, by avoiding intermixing of the two soils during the life of the structure. Geotextiles, when placed between fine soil and a coarse material (gravel, stone, etc), it averts the soil from blending and entering into the coarse material under the proceedings of repeated applied loads, hence it confirms mechanical nature of the coarse-grained soil is retained. Geotextiles are generally applied for separation when applied in roadway pavement sections. For separation, a proper geotextile must therefore be settled yet deformable; have a mass per unit area and strength that can resist mechanical stresses while installation without any damages and at the same time acts as a filter.
Filtration: As a filter, geo-textile permits liquid to pass to its own plane while avoiding the largest part of the soil particles.
For this two cases may be applicable:
. a geotextile put across the flow of liquid in the associated region between two types of soils having diverse grain sizes
. a geotextile positioned in contact with soil permits water leaking from the soil to pass through, while averting any transfer of soil particles, such as in drainage pipes.
