Custom Soil Resource Report
Source of Sand and Gravel (Buckien Pit 11/2012)
This table gives information about the soils as potential sources of gravel and sand.
Normal compaction, minor processing, and other standard construction practices are
assumed.
Sand and gravel are natural aggregates suitable for commercial use with a minimum
of processing. They are used in many kinds of construction. Specifications for each
use vary widely. Only the likelihood of finding material in suitable quantity is evaluated.
The suitability of the material for specific purposes is not evaluated, nor are factors
that affect excavation of the material. The properties used to evaluate the soil as a
source of sand or gravel are gradation of grain sizes (as indicated by the Unified
classification of the soil), the thickness of suitable material, and the content of rock
fragments. If the bottom layer of the soil contains sand or gravel, the soil is considered
a likely source regardless of thickness. The assumption is that the sand or gravel layer
below the depth of observation exceeds the minimum thickness. The ratings are for
the whole soil, from the surface to a depth of about 6 feet.
The soils are rated good, fair, orpooras potential sources of sand and gravel. A rating
of good or fair means that the source material is likely to be in or below the soil. The
bottom layer and the thickest layer of the soils are assigned numerical ratings. These
ratings indicate the likelihood that the layer is a source of sand or gravel. The number
0.00 indicates that the layer is a poor source. The number 1.00 indicates that the layer
is a good source. A number between 0.00 and 1.00 indicates the degree to which the
layer is a likely source.
Information in this table is intended for land use planning, for evaluating land use
alternatives, and for planning site investigations prior to design and construction. The
information, however, has limitations. For example, estimates and other data generally
apply only to that part of the soil between the surface and a depth of 5 to 7 feet.
Because of the map scale, small areas of different soils may be included within the
mapped areas of a specific soil.
The information is not site specific and does not eliminate the need for onsite
investigation of the soils or for testing and analysis by personnel experienced in the
design and construction of engineering works.
