In this paper, polypropylene fibers including fibrillated polypropylene fiber (F) and multifilament fiber (M) were evaluated as potential stabilizers in enhancing volume changes behavior of bentonite. Two types of fibers and different fiber dosages were used in the tests. As a part of the research evaluation, a comprehensive laboratory experimental program was designed. The index properties and compaction parameters of bentonite, and bentonite-fiber mixtures were determined. Modified Consolidation Tests (Swelling Pressure Test) were conducted to assess the feasibility of using small particles of fibers as blended additive to mitigate the swelling potential of the bentonite. These experiments show that the bentonite can be successfully stabilized by two types of fibers. Test results were analyzed to establish optimum dosage levels for each of the fiber stabilizers.
