  • AASHTO Soil Classification System AASHTO Chart

    01/10/2019· The AASHTO Soil Classification System classifies soils into seven primary groups, named A-1 through A-7, based on their relative expected quality for road embankments, sub-grades, sub-bases, and bases. Some of the groups are in turn divided into subgroups, such as A-1-a and A-1-b. Furthermore, a Group Index may be calculated to quantify
