Combined Gradation Example
For this example, two coarse aggregates and one fine aggregate will be combined into the final product. These aggregates meet the requirements of Section 701.01 AGGREGATE FOR CONCRETE of the Standard Specification with the exception of Coarse Aggregate #2. Coarse Aggregate #2 doesn't meet the gradation requirement of Section 701.01.
Fine Aggregate Angularity - Pavement Interactive
The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1: Fine aggregate angularity test.
Fine Aggregate Specific Gravity - Pavement Interactive
The fine aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the coarse aggregate specific gravity test.

A Detailed Guide on Grading of Aggregates. - CivilSeek
Grading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up.

Coarse Aggregate. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve and will pass through 3-inch screen, are called coarse aggregate. The coarser the aggregate, the more economical the mix.
Aggregate in Concrete - The Concrete Network
The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired. The dividing line between fine and coarse aggregate is the 3/8-inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate.
