Gradation Test

The standard gradation and sieve analysis test is AASHTO T 27 and ASTM C 136 Sieve Analysis of Fine and Coarse Aggregates Background The particle size distribution or gradation of the constituent aggregate (Figure 3) is one of the most influential characteristics in determining how an HMA mixture will perform as a pavement material Get price

What is Fineness Modulus of Sand (Fine Aggregate) and

Sieve Analysis of Aggregates

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 Get price

Sieve analysis

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass Get price
