Unified Soil Classification System Wikipedia
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soilThe classification system can be applied to most unconsolidated materials, and is represented by a twoletter symbol Each letter is described below (with the exception of Pt):gravel classification procedure Understanding the Geotechnical Report as an This will usually identify the soil by classification of particle sizing such as cobble gravel sand silt or clay etc Most soils are a combination of these classifications meaning there is a gradation of material Sand and larger grains are often referred asgravel classification procedure V W Automation SA

cobbles, gravel, sand, silt, and clay Numerous grade scales have been developed to establish the limits of size for each of these classifications Table 3–1 shows some of the commonly used grade scales for comparison Note that the range in size for a particular class of particle may differ from one classification system to anotherJul 01, 2015· OnSite Identification & Classification of Soil The principle terms used by civil engineers to describe soils are Gravel (particle size larger than 475 mm) Sand (particle size within 475 mm to 0075mm) Silt & Clay (particle size less than 0075mm) Most natural soils consist of a mixture of two or more of these constituents and []HOW TO IDENTIFY & CLASSIFY SOIL ON SITE?
