Abstract: Expansive soils pose problems in design, construction and maintenance of civil structures. Lot of research is going on to improve the properties of expansive soils. The experimental results gathered over the past years show the potential for use of different types of fiber in improving properties of expansive soils. In this investigation effect of randomly oriented polypropylene fibers on CBR value, UCS value and shear parameters using direct shear test is studied. Fiber content is varied from 0.0% to 0.4% in steps of 0.1% (F0-F4 samples). Results indicate improved soil properties. UCS value increases from 7.4% to 24.43%; CBR value increases 23.55% to 59.88% ; cohesion increases from 5.9% to 26.80% and angle of internal friction increases from 24.84% to 53.79% with increase of fiber content from 0.1% to 0.4% compared to 0.0% fiber content(F0 sample).
Keywords: CBR Value, Cohesion & Angle of Internal Friction, Expansive Soil, Polypropylene Fibers, UCS Value.
Scope of the Article: Soil-Structure Interaction
