Using Textile Fibers as Soil Stabilizers New Achievements

Using Textile Fibers as Soil Stabilizers New Achievements

Abstract Techniques of improvement and treatment of the physical and engineering properties of soils which are used for embankments, base, sub-base, roadbeds and also for the upper layers of roads are called soil stabilization or soil reinforcement. A physical method of such improvement is the inclusion of oriented or randomly distributed discrete elements such as fibers. However, randomly distributed fiber-reinforced soils have recently attracted increasing attention in geotechnical engineering for the second time. Although the behavior of fiber reinforced composites has been extensively discussed by several investigators, however, very limited information has been reported on the use of randomly distributed discrete fibers for soil reinforcement. It is important to know that, only recently, the natural fibers have been tried in the field of soil projects. Consequently the aim of this paper is to investigate why, how, when and which fibers are used in soil reinforcement projects. In addition, the problems of sample preparation and water absorbance, in the case of natural fibers, will be discussed. As a final point, a generalization of short staple fiber composite theory and/or slippage theory will be conducted into the
experimental results of fiber reinforced soil derived from some investigational projects. Keywords: Fiber reinforcement, soil stabilization, natural fibers, synthetic fibers
