Fractal scaling has recently been proposed as a model for soil particle- size distribution ( psd). In this work, the cumulative number of soil grains greater than a characteristic size, n( r > r), and the cumulative mass distribution, m( r < r), are developed and shown to be proportional to r 3- d and r 3- d, respectively, where r is the grain size, r is a specific particle size distribution soil mechanics book pdf measuring scale, and d. Particle size distribution sieve analysis is used for coarse grained soils. Wet sieve analysis is suitable if soil contains fines.
