Reference: This is a classification of soil material for highway and airfield construction (Procedure M 145-73 in Am. Assoc. of State Highway and Transportation Officials, 1984. <br />COARSE-GRAINED SOILS, Sands, sands with fines, Clayey Sand. Reference: This is a classification of soil material designed for general construction purposes. It is dependent on the particle size distribution of the <75 mm, the liquid limit, and the plasticity index and on whether the soil material is high in organic matter (ASTM test D 2487, in ASTM, 1984). <br />4.23-14.11 5.1-7.3 <br />2 23-97 Loam Silt-Clay materials (more than 35% passing NO. 200), silty soils.

Assoc. of State Highway and Transportation Officials, 1984. <br />FINE-GRAINED SOILS, Silts and clays (liquid limit is less than 50%), Lean Clay. Reference: This is a classification of soil material designed for general construction purposes. It is dependent on the particle size distribution of the <75 mm, the liquid limit, and the plasticity index and on whether the soil material is high in organic matter (ASTM test D 2487, in ASTM, 1984). <br />4.23-14.11 5.1-7.3 <br />3 97-203 Sand Granular materials (35% or less passing No. 200), silty or clayey gravel and sand.
