Favored the gradation of ASTM C-33 (Fineness Modulus 2.15 - 3,38), but with a narrower limit on fineness modulus (2.40 to 2.95), Mr, Gray also thought that 2,5 percent was too restrictive for the amount of material passing the 200 sieve (he preferred 5 percent). Much of the ensuing discussion with Mr, Gray was concerned with fineness.A. Crushed stone with 90 fractured faces, LA Abrasion 40 per ASTM C 131, minimum CBR of 80 per ASTM D 1883. B.
