Extraction and isolation of stevioside and rebaudiana A from Stevia Bertoni leaves

Tanzania Journal of Science 2025

Summary

This study explored soil stabilization in road subgrade layers using nano-coir fibers and microplastic particles, conducting extensive geotechnical testing across multiple soil configurations. Results from tests including UCS, CBR, direct shear, and swelling pressure assessments evaluated how nano-coir and microplastic amendments affect the mechanical properties of subgrade soils.

This study explores a novel approach to soil stabilization in road subgrade layers through integration of nano-coir fibers and micro-plastic particles.Extensive testing, including liquid limit, plastic limit, UCS, CBR, Proctor, free swell index, mechanical analysis, moisture content, specific gravity, direct shear, consolidation, tri-axial, and swelling pressure assessments, was conducted on various soil configurations: unaltered soil, soil amended with 1.2% nano-coir fibers, 8% micro-plastic particles, and a combination of both.Additionally, the potential impact of nanotechnology on enhancing the performance of these modified soils is investigated.
