Soil Classifications Introduction

After you've entered your grain size and Atterberg test information, you may want to check the soil classification values that the program has calculated for your data. Begin by selecting Test > Enter Classifications Data, then use the various menu selections underneath Window (e.g., Window > USCS or Window > AASHTO, etc.) to view the program's classification windows.

• Although the program will normally extract the sieve percentages and Atterberg limits values needed to classify your soil directly from your grain size and Atterberg test data, you can also opt to skip entering testing data and directly enter your own sieve percentages and Atterberg values into the program's classification windows.
