Stabilization of Sub-Grade Material Using Quarry Dust

For pavements and other constructions to be stable and long-lasting, subgrade soil stabilization is essential in civil engineering. The application of quarry dust as an economical and environmentally friendly way to improve the qualities of sub-grade materials is the main topic of this study. It has been demonstrated that using quarry dust, which is a byproduct of the crushing process in quarries, as a stabilizing agent increases the strength and load-bearing capacity of soil. It has been noted that adding quarry dust to sub-grade soil improves compaction, lowers plasticity, and raises the California Bearing Ratio (CBR), all of which improve performance and workability under load construction. In this study, a sub-grade soil were collected for testing test. Compaction, CBR, and Atterberg limits test were among the laboratory studies used to evaluate how quarry dust affected the characteristics of the sub grade soil. The findings suggested quarry dust as a potential stabilizer for road building and other infrastructure projects since they showed a high degree of improvements in strength properties and decreased susceptibility to water. This technique offers a low-cost way to improve soil strength and lessen the environmental impact of conventional stabilizers, in addition making quarry dust waste a sustainable purpose.
