quarry dust due to the high fines of quarry dust, requires greater amount of water. Lohani et al. [34] reported the slump and compaction factor of concrete made with quarry dust for a w/c ratio 0.55. The slump and compaction factor was measured for replacement of fine aggregate by quarry dust at 0%, 20%, 30%, 40% and 50%

Soosan et al. have studied the effect of different percentages of quarry dust on compaction characteristics of three different soils and observed an increase in MDD values and decrease in OMC values with increase in dust content in the soil-dust mixes. The optimum range of quarry dust content in soil was found to be 40–60%.

The influence of quarry dust on compaction characteristics of expansive clay is presented in Fig. 8b, c, respectively. It can be recognised that, addition of quarry dust to expansive clay increases its maximum dry density and decreases optimum moisture content irrespective of its percentage added to natural soil. The increase in maximum dry ...

50% quarry dust and 10% cement reduced the liquid limit by about 41.8% and the plasticity index by about 42%. The maximum dry unit weight increased with cement and quarry dust content, while the optimum moisture content reduced with the same. The CBR of the natural soil increased from 6.3% to 130% at 50% quarry dust and 10% cement content.

Once the pavers have been installed on top of the stone dust bed, use a vibrating plate to compact the bed and pavers even more. However, note that stone dust doesn't compact well due to its powdery texture. It can cause shifting of the pavers later on which is why it's not really recommended to use this for your installation bed.
