Alluvial soil stabilization using polypropylene fibers and marble dust in the embankment of flexible pavement

Abstract

A solid infrastructure is built in part by stabilizing the soil. Strength of the earth not only bears weight of load, but also rigidity, stability, and strength of structure. A crucial component for the construction of any project is soil with sufficient bearing capacity. Construction best practices include actual classification of strength criteria. Researchers have always had a particular interest in soil stabilization, and a variety of techniques as well as numerous additives'most notably cement, lime, fly ash, etc.'have been used to stabilize soil. Utilization of marble dust powder and polypropylene fiber is main topic of interest in soil stabilization research10%, 20%, and 30% of the soil weight as well as 0.1%, 0.2%, and 0.3% of PPF soil weight were extracted as marble dust. To understand their impact on soil stabilization, many soil characteristics were investigated. OMC-MDD, CBR, and UCS are the criteria this study took into account. According to IS 2720, test was carried out. Soil having 30% marble dust produced greatest results for OMC and MDD, whereas the soil containing 30% marble dust (MD) and 0.1% polypropylene fibers (PPF) produced best results for CBR. The investigation results an acceptable and significant improvement of soil properties.
