The USCS was adopted in 1952. In 1969, the American Society for Testing and Materials (ASTM) adopted the Unified System as a standard method for classification for engineering purposes. The system uses both the particle size analysis and plasticity characteristics of soils. In this system, the soils are classified into 15 groups. Examples on soil classification - SlideShareFrom plasticity chart with LL=30% and PI=12%, the soil is located above the A-line, therefore the symbol is C 5. The final classification of the soil is SC (Clayey sand with gravel) Example 11) Classify the following soil using USCS % passing sieve # 4 = 100% LL = 55 % sieve # 200 = 86% PL = 27 % Solution 1.

The Unified Soil Classification System (USCS) and the American Association of State Highway and Transportation Officials (AASHTO) system are the common classification system we use in civil engineering practice. Learning objectives 1. Background of soil classification 2. How to classify soil using the Unified Soil Classification System (USCS) 3. Soil Classification System - Soil Mechanics - Civil Unified Soil Classification System USCS ChartAnd now we can complete our Unified Soil Classification System chart. Symbols used in Unified Soil Classification system are more descriptive and are more easily remembered. This classification system has also been adopted by Bureau of Indian Standards, making the Indian Standard Soil Classification System.

A.1.1 The Unified System The Unified system is the oldest system to be widely adopted, and varia-tions of this system still represent probably the most widely used form of soil classification in the Englishspeaking world. It was developed from a system proposed by Casagrande (1948) and referred to as the Airfield Classification System. Soil Properties and the Unified Soil Classification Unified Soil Classification System (USCS). In 1952, the Bureau of Reclamation (Reclamation) and the U.S. Army Corps of Engineers, with Professor Arthur Casagrande of Harvard University, reached agreement on modifications to his "Airfield Classification System" and named it Unified Soil Classification System (USCS).

The Unified Soil Classification System (USCS) The Unified Soil Classification System is based on the airfield classification system developed by A. Casagrande during World War II. With some modification it was jointly adopted by several U.S. government agencies in 1952.

A unified classification of soils is the most commonly adopted classification system of soil for engineering purposes.. It is, in fact, the universally accepted soil classification system.

Unified Soil Classification System - USCS Chart

The liquid limit and plasticity index in the Unified Soil Classification System are determined and plotted on the plasticity chart. The vertical line at LL = 50 separates high-plasticity soils from low-plasticity soils. The A-line separates clay from silt. The equation of the A-line is PI = 0.73 (LL 20) USCS Chart Unified Soil Classification System Training Unified Soil Classification System Training Part B - USCS using Laboratory Data Dirty Coarse-Grained Soils If a sample has less than 50 % Fines And it has more than 12 % Fines, it is a Dirty Coarse-Grained Soil To Classify, follow the flow chart and the following steps Dirty Coarse-Grained Soil Determine whether there is a greater % of Sand or Gravel % G = % finer 3 minus # 4 % S = % finer Unified Soil Classification System USCS Chart
