Was originally proposed by the Highway Research Board’s Committee on Classification of Materials for Subgrades and Granular Type Road. According to the present form of the system, soil can be classified according to eight major groups, A-1 through A-8, based on the grain size distribution, liquid limit and plasticity indices. -aashto -usda -mit -uscs

Soil engineering for highway design

Soil engineering is a part of geotechnical engineering that deals with the characteristics of soil. It also helps to understand the behavior of the soil in different conditions. The basic concepts of soil are studied to check the strength, compressibility, and porosity of the soil. This makes soil engineering an important topic for civil engineering.
