GENERAL SOIL SAMPLE NOTES Unless noted, all terms utilized herein refer to the Standard Definitions presented in ASTM D653. Standard Penetration Test (ASTM D1586): A 2.0-inch outside-diameter (O.D.), 1-3/8-inch inside-diameter (I.D.) split barrel sampler is driven into undisturbed soil by means of a 140-pound weight falling freely through a vertical distance of 30 inches. The sampler is normally driven three successive 6-inch increments. The total number of blows required for the final 12 inches of penetration is the Standard Penetration Resistance (N). Consistency COHESIVE SOILS Approximate Range of N Unconfined Compressive Strength (psf) COHESIONLE SOILS Density Classification Approximate Range of N Very Soft 0 1 Below 500 Very Loose 0 4 Soft 2 4 500 1,000 Loose 5 10 Medium Stiff 5 8 1,000 2,000 Medium Dense 11 30 Stiff 9 15 2,000 4,000 Dense 31 50 Very Stiff 16 30 4,000 8,000 Very Dense Over 50 Hard 31 50 8,000 16,000 Very Hard Over 50 Over 16,000 CLAIFICATION The major soil constituent is the principal noun, i.e. sand, silt, gravel. The second major soil constituent and other minor constituents are reported as follows: Boulders Cobbles PARTICLE SIZES - Greater than 12 inches (305 mm) - 3 inches (76.2 mm) to 12 inches (305 mm) Gravel: Coarse - ¾ inches (19.05 mm) to 3 inches (76.2 mm) Second Major Constituent Minor Constituents Fine - No.4 (4.75 mm) to ¾ inches (19.05 mm) (percent by weight) (percent by weight) Sand: Coarse - No. 10 (2.00 mm) to No. 4 (4.75 mm) Medium - No. 40 (0.425 mm) to No. 10 (2.00 mm) Trace 1% to 11% Trace 1% to 11% Fine - No. 200 (0.074 mm) to No. 40 (0.425 mm) Silt - 0.005 mm to 0.074 mm Adjective 12% to 35% Little 12% to 22% Clay - Less than 0.005 mm (clayey, silty, etc.) Some 23% to 33% And Over 35% If clay content is sufficient so that clay dominates soil properties, clay becomes the principal noun with the other major soil constituent as modifier: i.e., silty clay. Other minor soil constituents may be included in accordance with the classification breakdown for cohesionless soils: i.e., silty clay, trace sand, little gravel. If sand particle size is greater than 11% by weight of the total sample weight, the adjective (i.e., fine, medium or coarse) is added to the soil description for the sand portion of the sample, provided sand is the major or second major constituent.
