The liquid limit of expansive clay decreases with an increase in quarry dust content. It is observed from Fig. 7 a, the decrease in liquid limit is 22.35% and 29.17% for the addition of quarry dust content by 15% and 25%, respectively. The plastic limit of the expansive clay decreases from 24.66 to 18.87% (Fig. 7 b) at 20% quarry dust.

Quarry dust has particle sizes in the range of 0.05-5 mm and forms around 20-25% of the total output of rock crushing [6,10]. Large volumes of quarry dust are produced by rock quarrying industries which cause environmental problems. Only a little fraction of the quarry dust is used as filler in wearing courses of asphalt pavements [9].
