Mechanistic approach for fibre-reinforced flexible pavement

Abstract

Soil stabilization is the technique used to increase the strength and stability of soil. It is done by reinforcing the soil with various reinforcing materials, such as geotextiles, geo strips, geonets and fibers. The fibers used in the previous studies for increasing stability are carbon steel, saw dust, wheat husk, polypropylene, etc. Soil stabilization is done by reducing the layer thickness and extending the service life of the pavement. From the previous study, soil stabilization is done mainly by mechanical stabilization, physical stabilization, and by using polymers. Physical and chemical properties of the fibers also plays an important role in soil stabilization such as specific gravity, optimum moisture content (OMC), maximum dry density (MDD), etc. Various tests were performed to decide the optimum quantity of fibers on reinforced and unreinforced such as compaction tests, unconfined compression (UCC) strength tests, CBR tests, etc. Soil stabilization is the better option in terms of economy as well as energy rather going for deep foundation or raft foundation, which depends on designer.
