Permeability Evolution and Particle Size Distribution of
The permeability of crushed rock is determined by the pore structure, which has a close relationship with the particle size distribution . In recent decades, many related studies have been conducted to investigate the factors that affect the particle size distribution of granular materials [ 4 – 9 ].

Particle-size distribution
The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations. The log-hyperbolic distribution was proposed by Bagnold and Barndorff-Nielsen [9] to model the particle-size distribution of naturally occurring sediments.

THE DETERMINATION OF THE PARTICLE SIZE DISTRIBUTION OF AGGREGATES
The particle size distribution of aggregates is a determining factor for the wearing behaviour of asphalts and up to 2.0 mm. Dispensing with hand sieving should lead to a hypothesis that the material momentarily passing through the sieve is proportional to that material momentarily existing on the sieve and capable of passing through it
