Crushed Stone and Gravel Sizes, Chart and Grades -

2021-11-30  However, the particle diameter and uses are very similar, so are their application. Secondly, grades don’t tell you which stone wash crushed, i.e., granite, limestone, sandstone, or slate, but rather the stone size. Usually, the small the grade number, the coarser or large the gravel particle size, and the larger the number, the finer it is.

Compaction and seepage properties of crushed limestone ...

Particle crushing during compaction is a main cause of size 0–2.5 mm materials, whereas some fine particles are washed away due to the effect of water seepage, which is a main cause of weight loss. Non-Darcy seepage properties of the crushed limestone are strongly influenced by compaction and particle size distribution.
