Gradation Analysis A gradation analysis (or sieve analysis) is a procedure used to assess the particle size distribution (gradation) of a granular material by allowing the material to pass through a series of …

The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material.

The AASHTO numbering system labels aggregate specifications from 1 to 10 according to the largest stone size in the mixture, with 1 being the largest (all material passing a 4” sieve opening) and 10 …

Oct 5, 2019 · The proper grading of an aggregate produces dense concrete and needs less quantity of fine aggregate and cement waste, therefore, coarse and fine aggregates must be well graded to …

Oct 12, 2025 · What is Aggregate Gradation? Aggregate gradation refers to the distribution of particle sizes within a sample of aggregate. Essentially, it measures the range of sizes that make up the …

Apr 12, 2024 · The gradation of aggregates refers to the distribution of particle sizes in an aggregate sample. It is expressed in terms of percentages of the total weight of the aggregate sample retained …

Jun 21, 2025 · Aggregate gradation refers to the proportionate distribution, by weight, of different-sized particles in an aggregate sample. These particles may range from fine powders to larger gravel-sized …

The aggregate size, shape, and the way particles fit have an effect on the characteristic of the building material. The aggregate gradation describes the distribution of the particle sizes in a certain sample …

This guide provides a means to determine the optimal gradation of fine and coarse aggregates for use in the concrete mix using a set of tables. The tables are based on a computer model for the theoretical …
