Crushed Stone

 · Crushed Stone is a man-made construction aggregate typically produced in a quarry by passing stones through a crushing machine. (Gravel, in contrast, is produced naturally). The crushed stone is typically used as a base or underlayment, for example, where the concrete of a patio will rest. It's also used for drainage and landscaping.Boreholes were drilled to examine the depth of the crushed stones after soil improvement. One of the borehole logs is shown in Fig. 18.8.The stones were found to be present up to 9 m, in which the top 5 or 6 m was densely packed, whereas the remaining 4 or 5 m was embedded in clay.Below the crushed stone layer were a silty gravel layer and the weathered sandstone layer.Boreholes were drilled to examine the depth of the crushed stones after soil improvement.
