No. 10 gradation
AASHTO M43 and ASTM D448 define No. 10 by how much passes each sieve. Ohio DOT lists its nominal size as No. 4 to 0.
| Sieve | Opening | Percent passing |
|---|---|---|
| 3/8 in | 9.5 mm | 100 |
| No. 4 | 4.75 mm | 85-100 |
| No. 100 | 0.150 mm | 10-30 |
AASHTO M43-05 (ASTM D448) limits as tabled by FHWA.
How much No. 10 weighs
FHWA measured the dry unit weight of No. 10 at 115.8 lb per cubic foot loose and 146.3 lb dense. That is 3,126 to 3,950 lb, or 1.56 to 1.98 tons, per cubic yard. No. 10 is the screenings size (stone dust); FHWA measured about 11% of it passing the No. 200 sieve, against under 3% for the other sizes.
FHWA classifies No. 9 and No. 10 as poorly graded sands; the larger sizes are poorly graded gravels.
| Amount | Loose | Dense |
|---|---|---|
| 1 cu yd | 1.56 tons | 1.98 tons |
| 2 cu yd | 3.13 tons | 3.95 tons |
| 5 cu yd | 7.81 tons | 9.88 tons |
| 10 cu yd | 15.6 tons | 19.8 tons |
