#### Gradation and Size - Pavement Interactive

This shows that even a small amount of particles passing the 0.075-mm (#200) sieve results in very low permeability. Therefore, for base and subbase aggregates where permeability is important for drainage and frost resistance, many agencies will specify a maximum percent-by-weight passing for this sieve.

#### Sieve Analysis of Aggregates - Civil Engineering

sieve analysis Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates.This is done by sieving the aggregates as per IS: 2386 (Part I) – 1963. In this we use different sieves as standardized by the IS code and then pass aggregates through them and thus collect different sized particles left over different sieves.
