ASTM D2488-17e1 PDF Download

ASTM D2488-17e1 is a standard practice that provides procedures for describing and identifying soils for engineering purposes. The descriptive information obtained through this practice can be used to evaluate the significant properties of soils. It is meant to supplement the classification of soils as determined by Test Method D2487.

This practice can be used to identify soils using the classification group symbols and names prescribed in Test Method D2487. It is important to note that the identification of soils based on this practice relies on visual-manual procedures, and this should be clearly stated in reports and other relevant documents.

The standard can be used to describe and identify soils in various settings, including the field, laboratory, or any other location where soil samples are inspected and described. It may also be used to group similar soil samples, reducing the number of laboratory tests required for soil classification.

Certain sections of the standard provide additional guidance and considerations. For example, the ability to describe and identify soils correctly can be learned under the guidance of experienced personnel, or by systematically comparing numerical laboratory test results with visual and manual characteristics. Additionally, soil samples that exhibit similar characteristics are not required to follow all the procedures in this practice, as long as at least one sample is completely described and identified.

The standard also provides guidance on working with frozen soils in combination with Practice D4083. It emphasizes that the competence of personnel and the suitability of equipment and facilities are crucial for reliable results. Compliance with Practice D3740, which evaluates such factors, does not guarantee reliable results on its own.
