Improving the characteristics of dispersive subgrade soils using lime [PDF]
Heliyon, 2020 Dispersive soil arises significant problems that need attention in geotechnical Engineering. Such soils are easily erodible and keep apart due to the difference in moisture content and exchangeable sodium. This study focuses on enhancing sub-grade of the road by stabilizing dispersive soil with lime, and it provides better index properties, reduces ...

Hydrophobic Effect of Soil Stabilization for a Sustainable Subgrade Soil Improvement
Materials, 2022 The chemical process of using additives to stabilize soils is to improve soil that lacks strong engineering properties. In particular, the moisture susceptibility of subgrade soil through seasonal rains is still questionable. The presence of water in the construction is the cause of deterioration and premature distress of pavements and their supporting
