Description and identification of soils visual-manual procedure

Test Procedure for MANUAL PROCEDURE FOR DESCRIPTION IDENTIFICATION OF SOILS TxDOT Designation: TexE Effective Date: August 1. SCOPE This method describes and identifies naturally occurring soils based on visual examination and simple manual tests. Perform the procedure in the field during sampling. Soils (Visual-Manual Procedure). Coarse-Grained Soils. Coarse-grained soils are those soils where more than half of particles finer than 3-inch size can be distinguished by the naked eye. The smallest particle that is large enough to be visible corresponds approximately to the size of the opening of No. sieve used for laboratory identification. Complete identification.  · Description / Abstract: ASTM D, Edition, J - Standard Practice for Description and Identification of Soils (Visual-Manual Procedures) This practice covers procedures for the description of soils for engineering purposes. This practice also describes a procedure for identifying soils, at the option of the user, based on the classification system described in Test .

Identification of soils by visual means in the field; Identification of soils by manual and handling examinations; Identification of soils by grain sizes, textures and shapes; Soil conditions, moisture conditions that become accessible during excavations, borings etc; Determination of approximate soil moisture as an indicator of existing soil conditions; and; Commonly used soil names and descriptions. The word-picture is the description of the soil sample as determined by the visual-manual procedure. Where applicable, the following are to be included in the word picture: PERTINENT INFORMATION EXAMPLE 1. Color of the sample Brown 2. Description of Soil Components Silty GRAVEL 3. Moisture Condition moist 4. Plasticity nonplastic 5. It shall be clearly stated in reporting, the soil identification is based on visual-manual procedures. When precise classification of soils for engineering purposes is required, the procedures outlined in Test Method D shall be used. In this practice, the identification procedures assigning a group symbol and name are limited to soil particles smaller than 3 in. (75 mm). The identification portion of this practice is limited to naturally occurring soils.
