Geotechnical Characterization of a Clayey Soil Stabilized with Polypropylene Fiber Using Unconfined Compression and Resilient Modulus Testing Data

Source

This paper focuses on the geotechnical characterization of a clayey soil and its mixture with polypropylene fiber. The laboratory testing program was directed to: (i) analysis of the influence of fiber content and fiber length on the unconfined compression strength of a clayey soil in order to determine optimum parameters to be used in repeated-loading triaxial tests, and (ii) analysis of the influence of fiber on the resilient modulus of the clayey soil, according to the Brazilian Standard DNER-ME 131/94. The laboratory testing data support that: (i) the mechanical response of the composite is fiber content and fiber length dependent; (ii) addition of fiber to the soil improves substantially its unconfined compression strength; and (iii) addition of fiber to the soil is also responsible for substantial decrease in its MR values, and produces a composite that can be useful in road engineering practice.
