In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.

Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.

In this grade, there are rocks the size of 2” to 4” in diameter. This grade is usually used for things such as filling wire baskets, and bases for access roads. #3 Aggregate: This grade contains stones that are somewhat smaller in diameter and is mostly used for lining drainage channels and railroad beds beneath the train tracks.

The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides are lative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact.
