Compaction Characteristics of Red Earth and Quarry Dust Combinations

Quarry dust is a waste material obtained during the quarrying process. It exhibits high shear strength and good permeability. An efficient method to dispose it off is by using it in combination with red earth to strengthen the soil. This paper presents effects of addition of quarry dust on properties of red earth and the relationship between water content and dry density of quarry dust–red earth mixes. Preliminary studies concluded that the optimum proportion of quarry dust–red earth mixes was found as 40% and 60%, respectively. The optimum values of the mixes are defined with respect to the dry density of quarry dust alone. It is observed that there was an increase of 11.61% in the dry density when 40% of the red earth is replaced with quarry dust. The optimum value of quarry dust to be mixed with red earth so as to have maximum shear strength is also determined. The shear strength of the mix was found from direct shear tests, and it was observed that there is a reduction in the shear properties when quarry dust was mixed with red earth. However, quarry dust can be a sustainable solution to sub-base stabilization especially in case of highways.
