  • Crushed Stone Grades: A Complete Guide

    By definition crushed stone is a construction aggregate. It is created by mining a suitable rock formation and then using a crusher to break down the stone into different sizes. Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of FAA Gradation Requirements after compaction of P-209,FAA Gradation Requirements after compaction of P-209 DDBPE (Civil/Environmental) (OP) 30 May 13 13:13. On a recent project, the P209 met specs for material properties and gradation at the plant. Then after 100% compaction the specs require the gradation sample to be taken from the in-place compacted material.
