A "good" gravel (Image 1) should have 40 to 70% stone, well-graded from 1/4" to 2-1/2" diameter; 20 to 50% sand; and 10% +/- fines. It should resist abrasion, shed water and be capable of being compacted. A "good" porous aggregate (Image 2) should be poorly-graded from 3/8" to ¾" diameter; with 25 to 40% porosity.
