Sieve Analysis of Coarse Aggregate: The Test Procedure

A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements. Data can also be used to better understand the relationship between aggregates or blends and to predict trends during production.

How To Do Sieve Analysis Of Aggregate

Nov 09, 2014 2. Reduce the sample to “Minimum Mass of Test Portion.” There are minimum masses that you would need to take corresponding to each size of aggregate that you are going to do sieve analysis.This time we’re going to use 20mm aggregate, so we will reduce the sample to 2 kilograms (minimum weight) but you can make it more than 2kgs as long as you will follow the process.

The Art of Sample Prepping for Coarse Aggregate Sieve

Aggregate and other materials sampled in the field need to be reduced to appropriate sizes for lab testing while minimizing the introduction of variability during handling. In some cases, a few particles on a sieve might affect a gradation enough to alter an interpretation of the field sample and consequently the entire site’s compliance with

Fine Aggregate Specific Gravity Pavement Interactive

If the aggregate slumps on the first Cone Test, it is assumed that the aggregate has already dried beyond the SSD condition (Figure 10). The aggregate can be restored by thoroughly mixing in a small amount of water and allowing the aggregate to stand in a covered container for 30 minutes. The drying process can then be resumed (AASHTO, 2000c [1]).
