ASTM D2487 Unified Soil Classification System - ANSI Blog
2018年3月15日 · ASTM D2487-17: Standard Practice for Classification of Soils for Engineering Purposes (Unified Soil Classification System) covers 15 distinct groups and abbreviations for gravel, clay, silts, etc under coarse-grained soils, fine-grained soils, and highly organic soils.
Plasticity chart for the Unified/ASTM soil classification 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.
