Gradation testing, also called sieve analysis, is a fairly basic yet essential test that measures the gradation (or distribution of aggregate particles, by size, within a given sample) to determine whether it’s compliant with design, production control requirements, and verification specifications.
Based on rockfill construction experience and engineering studies on several large-scale test fills, a general set of guidelines can be established for rockfill placement and compaction as discussed below. Typical rockfill placement and compaction operations, as well as large scale rockfill density and gradation testing are shown on Photos 1 to 7.
Soil Testing Equipment We provide array of Soil Testing Equipment which are capable of providing static and dynamic tests.

Sieve analysis equipment is used to characterize and classify sand, aggregate, soils, coal, grains, and many types of fine powders. With our large inventory and wide range of ASTM (American Society for Testing and Materials) and ISO (International Organization for Standardization) Test Sieves, Gilson is the best source for your sieves and particle size analysis equipment.
We also provide a variety of hand shear vane testing equipment for determining soil shear strengths. Humboldt also provides probes and augers for in-field soil sampling, as well as soil resistivity testing and moisture testing. Humboldt provides a wide selection of soil testing equipment for field applications.
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.
Sample sizes in Table 1 are standard for aggregate sieve analysis, due to equipment restraints samples may need to be divided into several “subsamples.” For example, a gradation that requires 100 kg (220 lbs.) of material would not fit into a large tray shaker all at once.

Our testing equipment also includes abrasion testing, rock testing, moisture and specific gravity testing equipment.
Particle Size Determination or particle measuring, using test sieves entails the passing of particles through screens (sieves) of ever decreasing size. To effectively conduct sieve testing operations beyond the simplest manual sieve test, several components are needed. The basic element is the test sieve.
