This note explores the rationale behind the unified soil classification system for coarse-grained soils. A few deficiencies in the system are pointed out. A density function plot of the grain-size distribution is proposed to supplement the grain-size distribution curve, which the author believes will minimize the ambiguities and give a more realistic representation of grain-size distribution.
