Colloquially, the term gravel is often used to describe a mixture of different size pieces of stone mixed with sand and possibly some clay. The American construction industry distinguishes between gravel (a natural material) and crushed stone (produced artificially by mechanical crushing of rock.) The technical definition of gravel varies by region and by area of application. Many geologists d

Crushed stone Wikipedia

Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. It is distinct from naturally occurring gravel, which is produced by natural processes of weathering and erosion and typically has a more rounded shape.

2 之The qualities of stabilized soil were evaluated using the Atterberg limit, compunction, and CBR test. Crushed stone dust was used to stabilize the soil in stepwise proportions of 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50% by dry weight of soil. The results suggest that adding crushed stone dust to the soil improves its geotechnical properties.
