Custom Soil Resource Report
potential, soils that have a high water table, soils that have a claypan or clay layer at
or near the surface, and soils that are shallow over nearly impervious material.
These soils have a very slow rate of water transmission.
Depth to the upper and lower boundaries of each layer is indicated.
Texture is given in the standard terms used by the U.S. Department of Agriculture.
These terms are defined according to percentages of sand, silt, and clay in the
fraction of the soil that is less than 2 millimeters in diameter. "Loam,"for example, is
soil that is 7 to 27 percent clay, 28 to 50 percent silt, and less than 52 percent sand.
If the content of particles coarser than sand is 15 percent or more, an appropriate
modifier is added,for example, "gravelly."
Classification of the soils is determined according to the Unified soil classification
system (ASTM, 2005)and the system adopted by the American Association of
State Highway and Transportation Officials(AASHTO, 2004).
The Unified system classifies soils according to properties that affect their use as
construction material. Soils are classified according to particle-size distribution of
the fraction less than 3 inches in diameter and according to plasticity index, liquid
limit, and organic matter content. Sandy and gravelly soils are identified as GW, GP,
GM, GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, OL, MH, CH, and
OH;and highly organic soils as PT. Soils exhibiting engineering properties of two
groups can have a dual classification,for example, CL-ML.
The AASHTO system classifies soils according to those properties that affect
roadway construction and maintenance. In this system,the fraction of a mineral soil
that is less than 3 inches in diameter is classified in one of seven groups from A-1
through A-7 on the basis of particle-size distribution, liquid limit, and plasticity index.
Soils in group A-1 are coarse grained and low in content of fines (silt and clay).At
the other extreme, soils in group A-7 are fine grained. Highly organic soils are
classified in group A-8 on the basis of visual inspection.
If laboratory data are available, the A-1,A-2, and A-7 groups are further classified
as A-1-a,A-1-b,A-2-4,A-2-5,A-2-6,A-2-7,A-7-5, or A-7-6.As an additional
refinement,the suitability of a soil as subgrade material can be indicated by a group
index number. Group index numbers range from 0 for the best subgrade material to
20 or higher for the poorest.
Percentage of rock fragments larger than 10 inches in diameter and 3 to 10 inches
in diameter are indicated as a percentage of the total soil on a dry-weight basis.The
percentages are estimates determined mainly by converting volume percentage in
the field to weight percentage.Three values are provided to identify the expected
Low(L), Representative Value (R), and High (H).
Percentage (of soil particles)passing designated sieves is the percentage of the soil
fraction less than 3 inches in diameter based on an ovendry weight.The sieves,
numbers 4, 10,40, and 200 (USA Standard Series), have openings of 4.76,2.00,
0.420, and 0.074 millimeters, respectively. Estimates are based on laboratory tests
of soils sampled in the survey area and in nearby areas and on estimates made in
the field.Three values are provided to identify the expected Low(L), Representative
Value (R), and High (H).
Liquid limit and plasticity index(Atterberg limits)indicate the plasticity
characteristics of a soil. The estimates are based on test data from the survey area
or from nearby areas and on field examination.Three values are provided to identify
the expected Low(L), Representative Value(R), and High (H).
