You asked, "Are compaction tests of #610 crushed stone reliable?" The answer is yes. If a proctor, either D698 or D1557, can be performed on the material then in-place density tests can be performed on it. My recollection of the gradation for #610 stone is Percent Passing 1 ½" = 100 1"= 85-100 ½" = 40-75 No. 4 = 15-40
