Influence of adding fibers on engineering properties of clayey soils

Recently, research into alternative materials and methods has been ongoing with the goal of creating cuttingedge solutions for building earth structures. In circumstances when other alternative materials are employed, improving the soft soils used for these structures, such as the subgrades of highway embankments, might be essential for implementing sustainable and cost-effective applications. In order to examine the utilization of Polypropylene (PP), Copolymer (CP), and Virgin Homopolymer Polypropylene (VHP) fibers to stabilize two separate high and low-plasticity clay soils, comprehensive laboratory studies have been conducted. To estimate how these mixes would behave during earthquakes, a variety of soils and the aforementioned fibers were created in the lab. The engineering features of these combinations were then studied. Investigations were conducted into the engineering behaviors of the samples as well as the results of the compaction, unconfined compression, CBR, and cyclic triaxial testing. The results of the laboratory study are presented in this work, with a focus on the usage of alternative materials that produce stronger soils during earthquakes, which has positive economic and environmental effects.
