What is AASHTO and USCS Soil Classification Guide about?

This document provides procedures for classifying soil samples using two systems: AASHTO and USCS. For AASHTO classification, data on grain size distribution, plastic limit, and liquid limit are used to determine the soil type based on tables. A group index value is also calculated to determine subgrade rating. For USCS classification, the same data is used along with coefficients to classify the soil based on tables. Procedures for USDA classification are also provided but not described in detail.
