Aggregate Texture and Shape, What You Should Know

The effects of the particle size and gradation of construction aggregates used in asphalt or concrete aggregates or on their own as compacted base materials are widely known, but particle shape makes a difference. The shape, aspect ratio, and texture of construction aggregates significantly influence the performance of the finished product.

Gradation of Coarse Aggregate by Sieve Analysis

The graded coarse aggregate is defined by its nominal size i.e., 40 mm, 20 mm, 16 mm, 12.5 mm, etc. For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel, …

applications. Gradation affects many properties of an aggregate such as density, physical stability and permeability. Therefore, the grain size distribution of a material can be important in understanding its physical properties. Gradation describes the distribution of the different size groups within a soil sample.

Most ready-mix concrete producers use their own methods, hire a testing lab, or rely on a vendor. These methods often include a concept of "ideal gradation.". From Fuller's maximum density curve, the .45 power curve, 8-18, gap grading to the latest "tarantula," the aggregate gradation has a major impact on performance.

A sieve analysis, or 'gradation,' measures distribution of aggregate particle sizes within a given sample. Accurate determination of the amount of material smaller than 75 μm (No. 200) cannot be made using just AASHTO T 27. If quantifying this material is required, use AASHTO T 11 in conjunction with AASHTO T 27.
