KEY TO SOIL CLASSIFICATION V
CLASSIFICATION OF SOIL CONSTITUENTS
BY PARTICLE SIZE ASTM D 2487 and 2488
Category
Particle Diameter
Silt and Clay
Soil passing a No. 200 (75- m) sieve
Fine — Particles of rock passing the No. 40 (425-µm) sieve and
retained on the No. 200 (75-µm) sieve
Medium — Particles of rock passing the No. 10 (2.00-mm) sieve and
Sand
retained on the No. 40 (425-µm) sieve
Coarse — Particles of rock passing the No. 4 (4.75-mm) sieve and
retained on the No. 10 (2.00-mm) sieve
Fine — Particles of rock passing the %-in. (19-mm) sieve and
retained on the No. 4 (4.75-mm) sieve
Gravel
Coarse — Particles of rock passing the 3-in. (75-mm) sieve and
retained on the %-in. (19-mm) sieve
Particles of rock passing 12-in. square opening and
Cobbles
retained on a 3-in. (75-mm) sieve
Boulders
Particles of rock that will not pass a 12-in. square opening
