AN EXPERIMENTAL STUDY ON STRENGTH BEHAVIOUR OF EXPANSIVE SOIL STABILIZED WITH POLYESTER FIBER AND LIME

Abstract

In vast areas the expansive soils are located along the central India, which foist enormous construction problems to geotechnical engineers.Expansive soil has a clay mineral Montmorillonite,can imbibe large amount of water and undergo volume changes causing shrinkage and seasonal heave in foundations, pavements, embankments, retaining walls that generate vandalization thestructure thatimplies loss of crores of money. To reduce its impact in fields there is necessary to improving the soil characteristics by stabilization.  Now a day’s synthetic fiber such as polyester fibers are used as stabilizing material those are fabricated from plastics. Plastics create environmental pollution as per 2018, about 380million tonnes of plastic produced worldwide each year.By recycling the plastic which can be used as stabilizing material in the configuration of polyester fiber. Here lime is also used as additive increasing plastic property to soil. The current study assign with the strength behavior of the expansive soil. The accomplishment of polyester fiber and lime for make better the strength attributes to expansive soil. The laboratory tests are bringing off and conclusion are noticeable in this research paper.
