Crushed Stone: Sizes & Uses
#57, #8, ¾″ minus — which crushed stone goes where.
Crushed stone is angular rock produced by crushing quarried stone. Unlike rounded gravel, it locks together when compacted, making it ideal for structural base and drainage.
How do I calculate how much crushed stone I need?
Stone sizes are graded by number: smaller numbers = larger stone. #1 is 2–4″ ballast; #57 is ¾″ (the workhorse); #8 is ⅜″ chip; #10 is stone dust. 'Minus' products (¾″ minus, ⅜″ minus) include the fines and compact hard.
Weight is ~2,700 lb per cubic yard. For a compacted base, order by weight and specify the size and whether you want washed (clean, no fines) or minus (with fines).
