This standard provides a useful first step in any field or laboratory investigation for geotechnical engineering purposes. Significance and Use 5. The methods differ in the significant digits recorded and the size of the specimen mass required. The appropriate descriptive information from 287 D is included for illustrative purposes. Consolidated undrained triaxial compression test for cohesive soils1.
Unified Soil Classification System
The specimen should be soaked until all clayey aggregations have softened and then washed in accordance with Test Method C prior to performing the particle-size distribution. In-Place Conditions—Firm, stratified and contains lenses of silt 1 to 2 in.
Soil classification astm d standard test methods for liquid limit, plastic limit, and plasticity index of soils. American society for testing and materials reprinted. D 98 reapproved standard guide to site characterization for engineering design and construction purposes1 this standard is issued under the. Examples of such cases would be graphical logs, databases, tables, etc.
The additional descriptive terms that would accompany the soil classification should be based on the intended use of the classification and the individual circumstances. Standard guide to site characterization for engineering. Standard test method for low strain impact integrity testing. Some examples would be: Standard test method for bearing capacity of soil for static.
Determine espakl total wet weight of the fraction passing the 3-in. The fines are determined to be either clayey or silty based on 4287 plasticity index versus liquid limit plot on Fig. Compute the total dry weight of the sample and calculate the percentage of material retained on the 3-in.
D 12 standard test methods for laboratory compaction characteristics of soil using modi. Any particles adhering to the plus 3-in.
Save the water-content specimen for determination of the particle-size analysis in accordance with X3. It is a good check against erroneous data, and any test results that plot above or to the left of it should be verified.
The particle-size distribution 22487 be given in terms of percent of gravel, sand, and fines. For example, poorly graded gravel with sand, clayey sand with gravel. Photographs courtesy of engineering properties of soils based on espalo. Astm dpractice for classification of soils for engineering purposes unified soil classification system. Astm d is a widely accepted method for installation of thermoplastic pipe. This document cannot replace education or experience and should be used in conjunction with professional judgment.
When the laboratory test results indicate that the soil is close to another soil classification group, the borderline condition can be indicated with two symbols separated by a slash. However, the procedures used in this standard for describing the particle size and plasticity characteristics may be used in the description of the material.
NOTE 4—For particles retained on a 3-in. See area identified as CL on Fig. The basis for the classification scheme is the airfield classification system developed by a.
