For this substantial number of soils, boundary classifications are used i.e. the groups symbols most nearly describing the soil are connected by a hyphen, such as GW-GC. Proper boundary classification of a soil near the borderline between coarse-grained and fine-grained soils is accomplished by classifying it first as a coarse-grained soil and Unified Soil Classification System. Soils are broadly classified into three divisions: Coarse grained soils: In these soils, 50% or more of the total material by weight is larger than 75 micron IS sieve size.

    The Unified Soil Classification System, as outlined in ASTM 2488 – “Standard Practices for Description of Soils (Visual – Manual Procedure)”, provides a conventional system for classifying soils. However, it alone does not provide adequate descriptive terminology and criteria for identifying soils for engineering purposes. Therefore, the ASTM Standard has been modified to account for Geotechnical Manual Wisconsin Department of Transportation . Chapter 3 Wisconsin Soil Development and Distribution Section 3 Soil Classification Systems . There are a number of systems and methods used to classify soils.
