#57 Stone
Vulcan Materials Company · No. 57
A single-sized coarse aggregate in the No. 57 size, the most widely specified drainage and concrete stone in North America: nominally passing the 1 inch sieve and retained above the No. 4, with almost no fines, so it drains freely and compacts poorly by design. The producer lists it among its coarse stone products; the gradation itself is defined by the standard size-number table rather than by the producer.
