WebSoil Classification Systems 189 A.1.2 The ASTM System An advantage of the Unified system is that it can easily be extended to include more soil groups, giving a finer degree of classification if required. The American Association for Testing and Materials (ASTM 2006) has adopted the Unified system as a basis for the ASTM soil classification, WebThe Indian Standard Soil Classification System (ISCS), first developed in 1959, was revised in 1970. This revised version is essentially based on USCS with the modification that the fine-grained soils have been subdivided into three groups (low, medium and high plasticity) as against only two groups (low and high) in the USCS.

WebSoil Classification 3.1 INTRODUCTION Soils can behave quite differently depending on their geotechnical characteristics. In coarse grained soils, where the grains are larger than 0.075 mm (or 75 µm), the engineering behaviour is influenced mainly by the relative proportions of the different sizes present, the shapes of the soil grains, and the ...
