#67 Crushed Stone: Uses, Coverage & Calculator
A slightly tighter-packing cousin of #57: angular 3/4″ stone with some smaller pieces mixed in, for driveways, drainage and concrete work.
What is #67 Crushed Stone?
#67 is crushed stone graded from about 3/4″ down to roughly 3/16″. It is washed, so it carries very little dust, but the range of sizes means smaller pieces fill some of the gaps between larger ones.
That mix gives #67 a slightly firmer, more stable feel than #57 while still letting water drain through. Contractors use it for driveway surfacing, drainage beds and as a coarse aggregate in concrete.
